How a Pressure Tank Works and why you need a Cycle Stop Valve

[@steelman63weldandfab98]

Awesome well explained video! Im definitely getting a CSV. I have a pressure tank system (well x trol professional) 80 gal. Way oversized for the house but with a csv the pressure drop goes away,outstanding! This vid has excellent detail for the novice or trained professional (maintenance mech for large steel corp.) Thanx again for the info.

@@cyclestopvalves8380 I deleted my post for 2 reasons, I have only seen videos of why not to have a csv, They can be misinformation since I noticed a few sketchy things that make you doubt truth or lie. Common Sense tells you if you return the same water in a small test tank and cycle a pump, it's going to heat up so going to investigate further before making a statement that may not be right. Second, I do notice a big amp drop after start up so you may be right, keeping it running may allow it to run better and longer, Personal experience with jet pumps, I notice you can get double the life by just letting it run and I can say that with truth since I did just that, my old jet system never shut off on purpose, got tired of changing pressure switches and even a small issue, shut down, clear system, fix issue, waste time priming lines and rinse/repeat, I set it to run constant and had little issue's plus it stayed cooler, I switched to submersible and kept the same set up except my pump works so good, it fills the 30 gallon tank so fast it barely ever runs for 15 seconds every couple hours unless you use washer/tub/shower. Even then it barely cuts on, But if your csv does what it says, pump barely will ever run at even 50%, I would guess like jet pump, draw less power, never trip the pressure switch and still keep 33psi, the only question I have is what happens to back pressure from not using water, would that not build back pressure? My jet pump returned water in a loop but the sub has no return, what happens to back pressure? Pump would be pushing water with no where to go if nothing is being used.

[@cyclestopvalves8380]

@@Klemin2012 Thanks. You are starting to understand. There is no water being recirculated. If you are not using the minimum 1 GPM coming through the CSV, then the 1 GPM fills the pressure tank until the pump is shut off. Jet pumps don't drop much in amps, but are air cooled motors and doesn't make any difference on water flow for cooling. The back pressure will be as much as your pump can build when thinking the well is deeper, which is how the CSV controls flow. But no pump can build more pressure than it can stand. Back pressure is a good thing as that is what makes the amps drop and the motor to run cooler.

[@wpaul33]

My main concern on the Cycle Stop Valve is the increase in backpressure. I've read many positive reviews on your website about them but also many of those same positive reviews have had fittings blow apart and or leaks due to the increased back pressure between the pump and pressure tank. Although I see the need to try and reduce pump cycle's the last thing I want to do is have to dig up a water line or pull the well pump due to fitting failure from the increase in back pressure. My Franklin Electric Pump lasted 23 years before needing to be replaced on the traditional pressure tank and switch system.

[@cyclestopvalves8380]

Back pressure is good for the pump, cannot be any more than your pump can make, and the CSV itself has a limit. I only know of one idiot who blew off the incoming pipe, he just posted it on Amazon, which we do not do business with, so they keep that post up top. Lol. If your pump lasted 23 years without a CSV, it would last 40-50 years with one. We have only done this about a million times over the last 30 years. So, look at your pump curve, figure out how little back pressure it can build, get over your concern, and start enjoying strong constant pressure instead of seeing that pressure go up and down over and over and over.

[@h2omechanic]

So if my pump is capable of build 175psi, but my pipe before the cvs is 125psi pipe, wouldn't i need to worry about it blowing up the pipe? Older 1" black roll.

[@cyclestopvalves8380]

Yes. That is why we check those things when recommending a CSV. But usually there is only 30-50 PSI more on the pipe than the normal pressure that happens because of the depth of the well and the pressure on the pressure switch. If the pump is 260' deep when the pressure switch gets to 60 there is 175 PSI on the pipe at the bottom of the well, even without a CSV.

I have a well with a submersible pump but water comes out for only about 7-12 minutes depending on the time of the year. I am wanting to add a cabin on my property and plan on burying a water cistern near the house. I am going to buy a timer switch for the well pump so that it comes on multiple times per day and will fill into the cistern. Since I am only there on weekends or maybe once a month I should be able to capture enough water in cistern to service my cabin, sprinkler system and maybe a drip irrigation system. My plan is to put a submersible pump in the cistern and run it to a little pump house and then out from there. Your video makes sense and I am thinking I need your kit with the CSV. I have limited knowledge of these types of systems so I am wondering what type of submersible pump I need for my cistern (HP and GPM) to make all of this work using your system. Thanks.

[@cyclestopvalves8380]

How many GPM's do you have running for 7-12 minutes to pump the well dry? Even a well that only makes 1 GPM can still give you 1440 gallons every day. You need a Cycle Sensor for the well pump to protect it from running dry, and it will be your timer as it is built into the Cycle Sensor. You can use a Cycle Sensor on the cistern pump as well, so it shuts off if the cistern is run dry. Because of the price many people are using the 1HP, 33 GPM, Hallmark pumps in cisterns. I prefer the 230V version. Used in combination with our PK1A kit you can have all the water you want at a strong constant pressure. See this link. forum.cyclestopvalves.com/index.php?topic=1841.0

[@cyclestopvalves8380]

Thank you! All filters, softeners, and such should be placed after the CSV/pressure tank on the line going to the house. Keep in mind filters and softeners lose quite a bit of pressure through them. So, you may want to set up your system with 60 PSI constant from the CSV using a 50/70 pressure switch instead of the usual 40/60 pressure settings.

Does the well pump continue to try and make water at the usual pump flow rate? There does not appear to be any current limits placed on the submersible pump by the CSV that I can see. There is no electrical control going on between the pump and the CSV. Correct me if I'm wrong but,I can understand how when there are several things using water at the same time, the CSV might eliminate a cycle on on and off , however how would this save energy, and save your pump from excessive wear? Putting a restriction on the flow of water leaving the pump seems like a dead heading measure. The pump continues to pump at it's usual force but is held back by the CSV regulator. If there were a lessening of energy sent to the pump , wouldn't that be a method of throttling it vs physically impeding the flow? Please explain and thank you for the video.

[@cyclestopvalves8380]

Those are very good questions. The CSV can never completely close, so it can never deadhead a pump. There is no electric to the CSV. Pumps just normally reduce in amperage when restricted with a valve of any kind. Here is a video to explain the technical stuff. kzbin.info/www/bejne/aXikc5uCgdmdl9U

One gallon of water weighs 8.33 pounds. It takes a lot more HP to lift 50 gallons a minute than is does to lift 1 gallon a minute. Restricting the pump to make this happen causes the impeller(s) to just spin in nice cool lubricant and not draw any load, as they don't actually touch anything.

I’m curious what the pressure would be on the line from an average submersible pump to the valve? And why couldn’t you use a larger pressure tank to reduce cycles when you only need say 2-3 gallons?

[@cyclestopvalves8380]

There is no average pressure from a submersible pump. Every pump is different and the water level in every well is different. It is not common to have more than about 150 PSI, but 90-120 is more common. Give me the size of your pump and the water level in the well and I can tell you exactly how much pressure will be before the CSV. And sure you can use as large a tank as you want with a CSV, if you just like wasting money, space, and waiting on the strong constant pressure to happen. It doesn't hurt if your pump cycles for every 2-3 gallons used, which is doesn't when you see how the CSV works. The CSV takes off so many cycles for the long term uses of water that you can't hurt the pump flushing a toilet even a hundred times per day. Pump companies labeled the CSV as a disruptive product almost 30 years ago as it makes pumps last longer and uses smaller pressure tanks. A product that is disruptive to the pump industry is the best thing you can do for your pump and your pocketbook. If pump companies don't like it, it is the best thing for you.

Even the new variable speed pumps just turn on and off all the time you are using water. But if you have a regular pressure switch it is probably not a variable speed pump and the Cycle Stop Valve will solve your problem and give you strong constant pressure in the shower.

[@r3tr0nic]

Interesting device, sounds like a special kind of pressure regulator. If I had to make an educated guess: It is like an adjustable high flow regulator (set to 50psi in this example), with a secondary, very restricted path (1gpm) that bypasses the regulator. This bypass path only allows pressure on the output side of the regulator to gain more then the regulator setting when the flow is less then 1gpm, and is critical in making this work. Very clever!

[@cyclestopvalves8380]

Thank you. Yeah so simple it is scary. Lol! We tried to see these to all the pump companies back in the early 90's. Took us several years to find out they blacklisted the CSV. Pump companies said the CSV is a disruptive product as it makes pumps last longer and use smaller tanks. Wow! Found something that makes pumps work better and last longer and the pump companies are doing everything in their power to discredit us and come up with variable speed pumps or Masscontrol flow switch controllers that don't make pumps last forever like a CSV does. Notice you don't hear from any of our customers from 20-30 years ago? The CSV made their pump systems work so well and last so long they forget they even have a pump system. When water comes out the faucet everytime you open it, you will never have to think about your pump system again.

[@OccamsRazor71]

In my basement, I have a 55 gallon pneumatic storage tank (20-40 psi, fed by typical submersible well pump/tank combo 100 ft away) prior to a Simer booster pump that increases pressure about 25-30 psi to around 65-70psi, feeding an 86 gallon bladder tank and house fixtures. The pump has its own (internal) on/off non-adjustable pressure switch. There are check valves and relief valves where needed, and a pressure reducing valve prior to the pump to prevent it from increasing pressure beyond 75 psi max. How might a CSV work in this system?

[@cyclestopvalves8380]

Wow! Sounds like a mess. A 55 gallon size pressure tank only holds 12 gallons of water. It is just a pressure tank, not a storage tank. You should be able to get all the pressure you need from the well pump, and not need a booster pump and all the other stuff. The 55 gallon pressure tank is much larger than needed with a CSV, but will work fine. Just turn up the pressure switch on the well pump to 60/80, and set a CSV1A for 70 PSI strong constant pressure to the house. Then you will not need the extra boost pump, 86 gallon tank, pressure reducing valve, etc. The CSV system will work much better. last much longer, and deliver stronger pressure to the house.

[@OccamsRazor71]

Thanks for the reply. The well pump and old tank combo serve two homes, with the tank likely not having much capacity after many, many years, and piping so old that to mess with it would likely require a complete re-do. Regularly, the well pump combo delivered no more than a trickle. Meanwhile, in the pneumatic tank (air over water), the capacity is actually closer to 50/50, providing sufficient storage draw for the booster pump, as the well pump, again, has low flow, low pressure. So, getting back to the booster pump and bladder tank, these have totally corrected a decades-long problem of having little to no water after short periods of use. One problem that remains though is correcting pressure ranging (40-70) still present, since booster pump only turns on once pressure sufficiently drops. So, back to original question, would a CSV work between the booster pump and bladder tank to keep pressure more steady, or is it a problem there is no pressure switch downstream of the booster pump?

[@cyclestopvalves8380]

Lol! Even 1-2 minutes of run time isn't enough. That is just the minimum. With a CSV the pump will run for as long as you are using water, then 1 more minute to fill the tank. You don't have to worry about "cycle duty" on a pump when it has a Cycle Stop Valve. Although you can use any size pressure tank you want with a CSV, even with the small tank there really is no way, as in no amount of flow for any length of time that will make the pump cycle repeatedly, which is what destroys most pumps. Cycle Stop Valves make pumps last many times longer than normal, not the other way around.

[@mrpush2532]

Hi, Ok so I have a question. Most pumps are not "regulated" due to flow demand. So if you have a standard jet pump or deep well pump, that typically provides a specific GPM at specified pressure, I see a problem at "low flow". Typically, the pressure tank handles the pumps capacity. With a CSV, there is no way for the pump to ADJUST to the low flow. You state that only "1 GPM" is required. How exactly is that possible without stressing the pump? My jet pump for example. When its on, its on, pumping at it max flow rate into the pressure tank. If I drop flow to 1GPM when that pumps wants to put out say 12 GPM, where is that "EXTRA ENERGY" being dissipated when my pump is trying to pump at 12 GPM? The pump is not a "variable flow" pump. That means that something is stressed somewhere. With low flow, is that impeller now cavitating because the pump is running full throttle and there is no where for the water to go? If so, that is going to cause PREMATURE failure somewhere in the closed system with pressure increases somewhere in the pump unless the pump has some why to overcome it. A CSV cannot throttle up or down a "NON VARIABLE SPEED" pump. How do you explain this? Thanks,

[@cyclestopvalves8380]

Lol! You would think so right? But that is not how pumps work. Pumps work on a curve. Your 12 GPM pump will produce 12 GPM at low pressure, or 1 GPM at a higher pressure. Submersibles will pump 12 GPM from a shallow well, but only 1 GPM if the well is deep enough. You don't have to slow a pump down to make it pump less water, just make it think it is in a deeper well by closing a valve to increase the pressure. The amazing and counter intuitive thing about pumps is that the amps or power needed decreases with flow, even though the pressure is increasing. Close a valve down to 1 GPM and the pump is only pumping 1 GPM. There maybe 100 PSI in the pump case, but the impeller is just spinning like a top in the perfect coolant and lubricant, and not drawing any load. Same thing happens when you put your hand over a blow dryer or vacuum cleaner. The amps don't go up, they are reduced when the flow is blocked off. You can hear the motor speed up because it it not blowing air and there is no load. Centrifugal pumps work the same way. The CSV just makes the pump think it is in a deep well when only a little water is needed, and makes the pump think it is in a shallow well when you open up more faucets to use more water. Proven science even though very few people understand how pumps really work. See the video about pump curves. Thanks

Interesting. How does the cycle stop valve respond to a low flowing well? I would surmise that it would only be able to maintain a constant pressure if the flow demand is less than the pump/well can deliver. If the flow demand exceeds the well's/pump's capability, will the valve close to the point that it flows only what the well/pump is capable of delivering, or will it start oscillating the pressure and cause short cycles? Also, what about winterizing? Does a bypass need to be installed to drain the house piping, or will water flow backwards through the valve? Lastly, what's required to winterize the cycle stop valve?

[@cyclestopvalves8380]

The Cycle Stop Valve will let you pump a weak well dry if you open too many faucets. The Cycle Sensor is designed to sense a dry well and shut the pump off. The pump doesn't cycle when it pumps the well dry, but it will burn out if not shut off fairly soon. The Cycle Stop Valve does allow you to use a very small amount of water without cycling the pump. So if your well only makes 4 GPM, and you only open 3 GPM worth of faucets, the CSV will make the pump only supply 3 GPM and you won't pump the well dry.

[@shofar-man]

The CSV sounds like a great idea. I also have some thoughts on the pressure tank. I think well tanks are poorly designed, possibly to avoid coating the inside of the tank. My thought is that the bladder should be for air rather than water. The bladder shape would not be critical and replacement could be through a port located on top of the tank for easy access so a homeowner could just pick up a replacement at home depot and install it w/o even fully draining the tank.

[@cyclestopvalves8380]

There are bladder tanks and there are diaphragm tanks. Some bladder tanks have the air inside the bladder, some have water. All diaphragm tanks that I know of only have water under the diaphragm. The most important thing to make a tank last is to limit the pump cycling. With every pump cycle the diaphragm or bladder expands and contracts. it is like bending a wire back and forth until it breaks. It is only going to take so many bends. You could use up all the bends in a short time by letting the pump cycle on/off too much, or you can make a bladder/diaphragm last many years by reducing or eliminating the cycling by using a Cycle Stop Valve. The second most important part of making a tank last is getting one where the bladder/diaphragm does not touch the sides when expanding and contracting. It is hard to make a bladder that doesn't touch the tanks sides, and easy to make a diaphragm expand and contract without touching the tank. Oh, and tanks with replaceable bladders are the worst, as they are made to need replacing regularly. In other words diaphragm tanks are better than bladder tanks, but any tank will last longer when working with a Cycle Stop Valve.

great video, and your assertion that even most plumbers don't understand the amp relationship to pressure.

I have a question about order of devices. Would it be OK if the first device once the water line comes into the house is a sediment filter?

The CSV125 valves do not like sand, but the CSV1A can handle quite a bit of sediment. However, it is always best to keep sand and sediment out of the CSV when possible. And as long as the filter is rated for the max pressure the pump can build, the filter can go before the CSV. Give me a pump model number and the depth to water in the well and I can tell you how much pressure will be on the filter before the CSV.

the well pump is 2ST52-12PLUS-P4-2 50' calculated head 200' distance to well with rise of 20' I was hoping to set csv to maintain 55. do think that would be possible?

[@cyclestopvalves8380]

That pump can only make 103 PSI max. If your water level is 75', that pump can only deliver 70 PSI to the surface. So yes you can run the CSV at 55 PSI with a 40/60 pressure switch. However, at 75' lift plus 55 PSI that pump can only produce 7 GPM. If you use more than 7 GPM the pressure will be lower than 55 PSI. As long as the filter is rated for 100 PSI or better it will be fine installed prior to the CSV.

[@allenjangula5869]

CSV sounds like a great way to blow you pipes apart or cause leaks as the back pressure greatly increases from 125 psi to over 300psi CSV sounds like a great way to increase your energy usage, it takes a lot more energy to increase water pressure from 125 psi to over 300 psi. CSV sounds like a great way to wear out your pump as the water vanes have 300PSI vs 115psi wearing against them. If you want constant pressure, invest in a freq drive pump.

[@cyclestopvalves8380]

All that was debunked over 30 years ago, which is also how long we have been using Cycle Stop Valves to replace VFD's or Variable Frequency Drives. I thought VFD's were great as well back in the late 80's and early 90's. Then I got smart and figured out pump amps will drop naturally without varying the speed. When I figured out a simple, inexpensive, long lasting, mechanical (no electric) valve was a better pump control than a VFD I never looked back. Someday maybe you will get smart too. All you have to do is research or test it for yourself to figure out everything you said is incorrect. You can't get a better pump control than a Cycle Stop Valve.

[@cyclestopvalves8380]

The pressure gauge has nothing to do with the function of the pump. The pressures switch will still turn the pump on at 40 and off at 60 even if there was no gauge. But gauges are like everything else in a pump system which is destroyed from the pump cycling on and off too much.

It seems that the pump runs all the time, even to maintain pressure but at different RPMs. Can you please clarify.

The CSV is just a simple valve. It cannot and doesn't need to control motor speed, just water flow. The pump only runs continuously when you use water, as compared to cycling on and off while you use water, which is bad for pumps.

Great explanation and thank you for the video. Do you run the risk of cavitating your pump blades by sending variable flows? Most pumps are designed to operate at a pretty strict flow and net head (pressure) range. Is the assumption here that you would need a pump that can effectively process a wide flow range?

[@cyclestopvalves8380]

The CSV can never close quite enough to cause cavitation. Most centrifugal pumps can handle a much wider range of flow than some people might think. Really as long as there is enough flow to keep the pump cool, cavitation is not an issue. Restricting the inlet line to the pump would cause cavitation, restricting the discharge of a pump only increases the head pressure, reduces the work the motor has to do, and even makes the motor run cooler.

@@andrewbenjamin3687 There is plenty on how the CSV works. It is just so simple you didn't realize that was all of it.

The minimum bypass in the CSV is what keeps the motor/pump cool, determines the rate that fills the pressure tank, and also determines the minimum usage rate at which the pump will not cycle.

First off great video, I have a few questions tho...So as the csv reduces the flow as needed, I can see the pressure go up on the pump discharge. How does the pump conserve energy if only the flow rate is reduced? The pumps output should be the same no matter the flow which is why the discharge pressure increases as the flow to the system is reduced correct? I understand the concept, but am wondering what kind of stess a csv would put on the pump and if it would reduce the life of the pump any. Thanks for the video and I look forward to getting my questions answered!

[@cyclestopvalves8380]

It is just the opposite of what you might think. Counter intuitive is the word. You can see as the pressure goes up on the pump discharge the amperage or power required goes down. The amperage is the "work" that the pump has to do. So when the amperage goes down the work goes down, which is easier on the pump, not harder. Most pump guys don't even know amperage or work goes down as pump discharge pressure increases. If you find a pump man who understands this counter intuitive fact about pumps, you found a good pump man. If a pump man doesn't understand how a pump really works he will try to sell you a VFD. But a VFD is just trying to trick a pump into doing something it already does naturally. Just most people don't know restricting the flow from a pump makes the pump draw lower amperage and last longer than normal.

Do you have a current meter test showing how much current pump is drawing using CSV and not using it, I know when I stall my tablesaw it blows breakers and draws much more current, can't be any good for pump motor to restick flow to almost nothing by creating a huge back pressure?.

[@cyclestopvalves8380]

You would think so right? I love showing people something they don't think is possible. You are right on the fence of figuring this out. A centrifugal pump is completely different than anything else, except some fans. With the heat off, put your hand over the discharge of a blow dryer. You can tell by the sound the motor speeds up. That is because there is less air being moved and less load on the motor. Put an amp meter on the blow dryer, and you will see the amps go down even though you can hear the motor speed up. Sticking your finger in the blow dryer and completely stopping the fan will have the opposite effect. The amps will go up the same as when you bind up a circular saw. Yes I have other videos showing the amp draw of several different pumps. There is even a video showing the horsepower on pump curves to better explain how a centrifugal pump works. The back pressure is never more than the pump can produce or withstand. The back pressure is like putting your hand over the blow dryer. It makes the amps decrease, which makes the motor run cooler. Back pressure is good for the pump even though it is the opposite of what our brains are telling us. Adding back pressure is a common fix for large irrigation pumps that are drawing too much current and tripping the breakers as it will decrease, not increase amps.

I am going to ask some questions that may also benefit others. If I bulk up the channel too much I think you can delete them. I have a 35 gal bladder tank that I just recharged. I will check run time occasionally to determine if the bladder is bad. I am thinking that with a CSV the short cycling experienced with a leaky bladder would not be a problem as it would still provide a buffer to allow the pressure switch to activate the pump and eliminate the short cycling. If that's the case tank replacement could be put off until a more convenient time or maybe forever if one were willing to keep check on the air.

[@cyclestopvalves8380]

Several things. If the system had a CSV to start with, the pump would not have cycled on/off enough to destroy the tank bladder. But yes if you have a water logged tank, the CSV will still keep the pump running while a toilet is filling or a shower is running, compared to clicking on and off rapidly several hundred times as it would without a CSV. Delays the need to replace the tank, but doesn't eliminate it. A good tank is needed, just not a large one. The CSV fills the tank at 1 GPM above its set point. So, no matter the size tank we try to set the CSV/pressure switch to get a minute of run time. This can be done with as small as a 4.5 gallon size tank that only holds 1 gallon of water. The CSV filling the tank at 1 GPM makes the tank more of a mechanical timer than a water storage vessel. The 1 minute of run time (which with the CSV only happens after you stop using water) is to make sure you are finished using water before the pump shuts off. As long as you are using more than 1 GPM the CSV just keeps the pump running continuously, water goes right past the tank, and the size of the tank is a moot point.

From these things I can back into which pump you have and find a curve. You can also use a pressure gauge before a ball valve and close the ball valve long enough to get a max pressure reading, which is really all we need to know if the CSV will work. Most pump systems are fine with a CSV. However, occasionally we run into a pump someone incorrectly installed that was made for for a 800'-1000' deep well, and the well water level is only 10'. That causes more back pressure than a CSV can handle, and is why you can't just put a CSV on without knowing something about the pump.

I am noticing that when I flush the toilet too many times in a row, too rapidly, the water turns off and I have to cycle the GFCI connected to the water pressure booster and then it turns back on. Similar behavior when I run a load of laundry with a front load washer (the valves opening and closing for the washing machine seem to trip up the water pump and the pump turns off, and then I have to again reset the GFCI it's connected to). I think I have a CSV installed in my system because when I turn on the kitchen sink, or the shower, the pressure starts low, then builds to the highest pressure and stays there the entire time it is in use. Recently though, I have noticed (and I am not sure if it is because of a heat wave we are experiencing) but I will be using just the kitchen sink and the water will die.

Don't think you have a CSV. The type pump you have uses a flow switch type control and electronic sensors. Probably doesn't even have a pressure tank, and wouldn't help much anyway. There needs to be flow through the pump or the pressure needs to drop pretty low before the electronics trigger the pump to start. Usually by the time the pressure gets low enough to trigger the pump there is no flow to help either. However, you shouldn't need more than one pump anyway. Just up the pressure on the first booster until you no longer need the second booster. A small pressure tank and a CSV on the first booster would let you set it to any pressure you want.

[@cyclestopvalves8380]

The CSV would have nothing to do with that problem. If your well only makes 7 GPM and you are letting out 23 GPM, the well will be pumped dry as soon as the extra water stored in the wells static level is depleted. Can probably only run 23 GPM for 10 minutes or so before you pump a 7 GPM well dry. Now if you have a 23 GPM pump and the well only makes 7 GPM, then if you only open up 7 GPM or less, the CSV will make the 23 GPM pump only put out 7 GPM or the exact amount you are using, so in this way the CSV can help keep from pumping the well dry. In low yield wells the Cycle Sensor will protect the pump if the well runs dry. Using the Cycle Sensor for protection and in combination with a Cycle Stop Valve will let you get the most out of any low producing well.

[@cyclestopvalves8380]

My math shows 400 gallons in 10 hours is 0.6 of a GPM. A jet pump with a CSV1A will stay running with flows down to about 0.5 GPM, and a submersible will stay running with as little as 1.0 GPM. So, if you have a submersible just use a little larger tank than normal with the CSV. Although it will still cycle, it will be a very slow cycle. With a 40 gallon size tank that holds 10 gallons of water, you supply pump will be still have to come on every 30-40 minutes.

Thank you for adding the back pressure valve in the illustration. People need to know/see that there is excessive back pressure being restricted to this side of the pumping system.

Good valves though, I use them in a few different applications.

[@cyclestopvalves8380]

There can never be "excessive" backpressure with a Cycle Stop Valve. The CSV itself cannot handle "excessive" backpressure. The only time you would have excessive backpressure is if you have a 100' deep well with a pump designed for say 500'. And that is not going to happen because the CSV will not even work in an application like that. The CSV will only work with less than 125 PSI differential pressure. So if you have the CSV set for 50 PSI, there cannot be more than 175 PSI coming from the pump. Many pump companies want you to think the CSV causes "excessive" backpressure. They don't want you to get the benefits of a CSV, because it will make your pump last longer. So they try to scare people talking about "excessive" backpressure, which in reality CANNOT happen.

[@Justinofalltrades1]

About how many years will this add to the life of the pump? Very curious, thanks

[@cyclestopvalves8380]

Believe it or not the CSV has been documented to increase the life of pump from 4 to 10 times. Our first test 30 years ago were on systems that cycled the pump to death every 2 years or so. Those systems last over 20 years with a CSV. Other systems where the pump lasted the normal 5-7 years the CSV has made last 30 years so far, and most are still working. You would not believe how long a pump will last when you reduce or eliminate the cycling on and off. That is why pump companies have labeled the CSV a "disruptive" product, as it makes pumps last much longer than the manufacturer wants it to.

[@hananhaganan8823]

restricting flow by applying reverse pressure heats the winding , in turn, may damage their insulation. the pump needs to work at it capacity unless its an inverter.

[@cyclestopvalves8380]

You could not be more wrong! Restricting the flow decreases amperage and heat in the motor windings, not the other way around. The pump can work almost anywhere on its curve without varying the speed. Fact is the high voltage spikes and rapid rate of switching from an inverter "VFD" cause high temperature in the motor windings and shorten motor life. Cycle Stop Valves make motors run cooler and last longer, which is why VFD or inverter companies feed you so much BS, trying to keep you from trying a CSV, which will make your pump/motor last 30+ years.

[@stevenfrazier8939]

Will this work with a Harbor Freight shallow well pump?

[@cyclestopvalves8380]

Yes, except some of those motors say "not for continuous duty". Only pump/motor I ever saw that says that. The Cycle Stop Valve takes all the jerking and cycling out, but I think these pumps are still made for light use. I wouldn't leave it running for hours on an irrigation system like with other pumps.

I own a trailer court and I have 3 trailers that is occupied. Can I use one of this to maintain better pressure when 1 or more is using water?

[@cyclestopvalves8380]

Yes you can. The CSV makes a big pump act like a small one when needed. So you can have a pump or pumps large enough to supply a huge city, and the CSV will make it act like a really small pump when only one shower in one house is being used at the time.

[@scottyoung8145]

Is the back pressure bad on my submersible pump?

[@cyclestopvalves8380]

Absolutely not! Back pressure makes pumps last longer for several reasons. I am sorry you have not got this from the many videos on my channel showing how it works. So I will just say it plainly. Back pressure reduces the amps and makes the pump/motor run cooler. Back pressure can also reduce the amount the pump is putting out. This is how a CSV makes the pump stop cycling, as cycling is the worst thing you can do to a pump.

[@RudyNortz]

I still don't get it. I'm thinking the pump puts put a fixed amount of water per minute. If the pump puts out more volume than is being used what happens to the excess flow? In other words, how does the CS valve vary the volume to regulate the pressure? Seems like there is a narrow range where flow rate and water usage would be close enough to reduce the number of pump cycles. The diagram seems to show there is a balance between flow rate and consumption. Wouldn't think this would be to common. There is still going to be pump cycling but at a lesser amount...?

[@cyclestopvalves8380]

I am sorry you still don't get it. As you can see I have tried many ways to explain this simple valve. And it is a simple valve. It just closes to reduce the flow from the pump, making the pump think it is in a deeper well, which makes it pump less water. The CSV just cannot close to less than 1 GPM. So as long as you are using more than 1 GPM the pump NEVER cycles. When you are no longer using any water, the 1 GPM coming through the CSV has no place left to go except the pressure tank. Then the pressure tank is filled to the pump shut off pressure and the pump is shut off. The next time you use water you cause another cycle. The pump only cycles for each individual time you start using water. But the pump NEVER cycles as long as the water is running, like systems without a CSV do.

what about the head pressure on the pump? 150 ft well plus two story house?

[@cyclestopvalves8380]

"Head pressure" is what a pump does. Even though your well is 150' deep and the pump maybe set at 145', it is still only lifting from the actual water level. So lets say the water level in the well is 100' at the lowest. Then you need a pump that can produce a head pressure or lift from 100', plus deliver the pressure needed in the house. With a single story house I would only use a 40/60 pressure switch. But with 2 stories I prefer a 50/70 pressure switch setting, which with a CSV will give you 60 PSI constant while the water is being used. This 60 PSI needed can be converted to head in feet by multiplying 60 X 2.31 for an additional 138' of head. The 50/70 setting is already making up the extra needed for the 20' elevation of the 2 story house. So adding the 100' of actual lift in the well to the 138' of head needed to make the 60 PSI for the house, gives a total head needed of 238' the pump must deliver. Now picking a pump that will do maybe 10 GPM at 238' means you need a 10 GPM, 3/4 HP pump. When using a CSV the head pressure on the pump will increase when you are using less than 10 GPM. When the CSV makes the pump produce only 1 GPM, because you are only using 1 GPM at the time, the pump will be seeing a head pressure of 310', which is the same as 134 PSI. So when using 10 GPM the CSV lets the pump draw from 100' and produce the 60 PSI needed in the house. But when only using 1 GPM, the CSV makes the pump think the water is 310' deep, which is how the CSV make the 10 GPM pump produce only 1 GPM when needed.

[@cyclestopvalves8380]

Look at your pressure gauge while you are experiencing low pressure. If the gauge is going from 50 to 70, and 70 to 50 over and over, a CSV will hold a constant 60 PSI, which believe it or not is much stronger shower pressure than the average 60 you get when cycling between 50 and 70. But if the gauge just stays low like 30, 40, PSI you just don't have a large enough pump to supply as many taps as you want to run. If the pump is cycling, a CSV1A would solve the problem and give you better pressure.

[@MrVinnied]

Cycle Stop Valves My gage does exactly that, cycles repeatedly. Not to be a cheep skate, would the CSV125-1 60psi solve my problem?

[@cyclestopvalves8380]

Yes the CSV12560-1 will work with that pump. And it maybe the one you need anyway as it is really designed to install in the well for systems that have a water line teed off the main before it comes into the house and to the pressure tank. But you can also install it close to the tank. If you have sand, iron, or sulfur in the water the CSV1A is a better choice. The CSV125 is also not adjustable, so you can't turn it down if that is needed. Also is there a chance you have a filter clogged up, as 50/70 should still be good pressure, just fluctuating.

[@MrVinnied]

Cycle Stop Valves I have a regenerative water softener, high iron. I have read reviews with similar situations, all positive results with the 12560-1. Will it matter where in line between pump and tank I install it?

I have 2.5 baths, and 7 faucets, washer and dishwasher, two hose bibs.

[@cyclestopvalves8380]

YES THEY DO! They hate it that the Cycle Stop Valve makes pumps last several times longer than their planned obsolescence date. So they will tell you anything they can to keep you from using a CSV, including saying that it will void the warranty. BUT they will not put that in writing. They know if they put that in writing I would own their pump company. Because not only can they not disallow a warranty for using a CSV, they have never seen a pump damaged in anyway in all these 25 years the CSV has been in existence. Restricting the flow from the pump reduces the amp draw and makes the motor run cooler. Plus restricting the flow is how the CSV keeps the pump from cycling itself to death, which is why pumps using a CSV last many times longer than those without a CSV.

Great animation. I am on a shared mutual well with about 70 homes. The pressure is ok, around 40. The house came with an old irrigation pump and two large tanks to accelerate water to farm and home. I replaced this with a Goulds constant flow variable pressure pump running 60/40 with a tiny ten gallon tank. The set up works great but i have a thump thump that occurs randomly throughout the day even though the breaker to the pump is off and I had a new brass ball check valve installed between pump and main line (to the shared well). When I bypass the pump entirely i have no check valve and can hear and feel vibration throughout the house as neighbors water their homes, yards, etc. The thumping only occurs when the pump is in line on or off electrically. My guess is the tank is making the noises. But why? What is making my tiny tank thump in the middle of the night when no water is being used, the pump is powered off by breaker and there is a new check valve?

[@cyclestopvalves8380]

Bladder tanks will thump when the pressure decrease below the air charge in the bladder. With 38 PSI air charge, the bladder hits the bottom of the tank anytime pressure falls below 38 PSI. Reducing the air charge in the tank will probably stop the the water hammer thump. Then all you need to do is get rid of that Tar Baby of a variable speed pump, install a regular jet pump with a Cycle Stop Valve, and you will have a pump system that will last 30 years in stead of maybe 3 years. Also, we make larger CSV's for larger pumps. The shared well for 70 homes could use a CSV even more than a small pump. The CSV would deliver better pressure to the 70 house, make the pump system last much longer, cut expenses greatly for pump control equipment, reducing cost to all concerned. We would only need an 80 gallon size pressure tank to do 70 homes with a CSV.

With a 40/60 pressure switch, the pump should come back on as soon as the pressure drops to 40. The CSV really has nothing to do with that. Either the pressure switch is not turning the pump back on for some reason, or the overload in the pump is tripping on startup. You might also have a low pressure cut off lever on the side of your pressure switch that you must hold to get the pump started. If that is the case, you could have too much air charge in the tank, causing the pressure to bottom out before the pump starts. 40/60 switch , needs 35 PSI air in the tank when empty of water.

KZbin needs to be fixed and do what they say they will do!!

I understand the long term use (Taking showers), but what about short term, flushing the toilet once wash your hands, seems like the pump will kick on filling the small tank rather then not kicking on having the bigger tank that will supply the water, not having the pump kicking on just because you flushed the toilet one time.

[@cyclestopvalves8380]

It is not the small things that cause cycling problems. It doesn't hurt if your pump cycles on for every toilet flush, although it doesn't. What hurts is repetitive cycling during long showers or watering the yard. Your water doesn't come from the tank, it comes from the well/pump. Pressure tanks are only to reduce the on/off cycling, and when you have a Cycle Stop Valve to do that for you, a large tank is just a waste of money and space. See this chart for number of cycles with or without a CSV for just house use only. The CSV and small tank still cycle less than a large tank with no CSV. Then if you have any long term uses like yard watering, there is no comparison as the CSV will cycle the pump only once, while without the CSV the pump will cycle hundreds of times.

Hi need your help i'm planning to buy a pump with pressure tank. my question is if the CSV will make a pump always on then i can get a more energy, (electric bill?) i am using the pump with pressure tank together the air compressor for my main washer instead the pressure washer for the stationary car wash business my purpose is to save energy or electric bill. please let me know what do you think if CSV is good for a carwash business hoping for your reply thanks.

[@cyclestopvalves8380]

The pump only runs when you are using water. Open a hose, the pump comes on and runs. Turn off the hose, the pump shuts off. Cycling the pump on/off actually uses more energy because it takes 6 to 9 times the running amps to start the pump. Lots of car washes using Cycle Stop Valves. Gives better pressure and makes the pumps last longer.

[@darbats]

okay where to buy the CSV send to philippines. do you have online shop for CSV?

[@darbats]

my pump is 1hp Self-priming Jet Pump pressure tank 100 liters.

[@cyclestopvalves8380]

You can find our on line store here. cyclestopvalves.com/pages/csv1a But you might need to call us so we can figure freight. Thanks

[@TheRainHarvester]

Yes, it might take 9 times more amps to start, but it doesn't take very long to start, so the power used isn't very much. I don't think you'll save electricity.

[@thebarn2730]

I don't get why my faucet doesn't do the same thing. I have read all of the explanations and looked at the videos and I still don't get how it works. Unless it is some combination of the faucet running, the tank filling, the spring moving and the cut off switch set between 40 and 60 psi. It took me a while to understand a ground fault interrupter too. I guess I will just have to get one and hope it works.

[@cyclestopvalves8380]

A faucet is after the pressure tank/CSV and only controls how much water you are using. The CSV is before the pressure tank/pressure switch and controls how much water your pump is producing. The CSV knows how many faucets you have open, and makes the pump produce exactly the same amount. Without a CSV the pump is always producing more than the faucet is letting out, which causes the tank to fill and the pump to cycle on and off. The CSV just matches how much the faucets are putting out so there is no extra water to fill the tank. You could do the same thing as a CSV with a ball valve before the pressure tank if you stood there and manually controlled it. With a 40/60 pressure switch the CSV would be set to 50 PSI. So if you saw the pressure drop below 50 you could open the ball valve a little and if you saw the pressure increase above 50 you could close the ball valve a little. The CSV will automatically keep the system at 50 PSI no matter how much or how little water you are using. You can't do that with a faucet.

[@bientrinidad8364]

how about i use 20/40psi what is the pressure when running continuesly

[@cyclestopvalves8380]

The CSV keeps the pump from reaching the shut off point as long as you are using more than 1 GPM. So, with a 20/40 switch the CSV would be set to 30 with a small tank, or 35 PSI constant if you have a larger tank.

[@dfossilo]

Wonderful video. I’d love to see a video with a holding tank and dual float switches. We are buying a home with a well that produces 3.6 GPM. The pressure tank is bad and we have to do some work. I wanted to have a 400 gallon plastic holding tank in the basement with a jet pump. Any information on this kind of system would be greatly appreciated. I love the animation. Thanks again.

[@cyclestopvalves8380]

I don't have a video but I do have several drawings of a cistern pump set up. Here is a link to one in my forum. forum.cyclestopvalves.com/index.php?topic=1840.0

[@Protek1]

Thanks! Well done, flow control, and pressure control. Much better system.

[@joulesramiro9513]

Wow, how do i purchase this device? Im from the philippines. Thus will solve my problem. Great product

[@cyclestopvalves8380]

There are several cities in the Philippines that use the large Cycle Stop Valves instead of a water tower. We ship to the Philippines quite often, one just last week. Call us or email and we can get one headed your way.

[@joulesramiro9513]

Cycle Stop Valves just wondering if you have like a package? With the pressure tank, csv etc....?

[@cyclestopvalves8380]

Yes that would be our PK1A kit, which you can see on the "Eliminate Big Pressure Tank" video on this channel.

[@rickgordon1701]

? I take water should not come out the air valve? Leaky bladder?

[@cyclestopvalves8380]

Correct. If water comes out the air valve on a pressure tank the diaphragm or bladder is torn.

[@russ320]

What about the new Variable speed pumps? Do you need a cycle stop valve? My neighbor has a VSP pump and a looks like a small

[@cyclestopvalves8380]

The Cycle Stop Valve or CSV was designed to replace Variable Speed Pumps or VSP's or VFD's, etc, etc. Variable speed pumps are not new. I was doing them back in the 80's. They have been around since 1964. However, VFD's have been "upgraded" or "de-bugged" every 18 months or so since VFD time began. They told me in the 80's that the newest model was going to solve all the problems of the last model, and they are still saying that today. They have made a LOT of improvements over the years, but laws of physics will never let them solve all the problems that happen when you vary the speed of a pump. VFD's are a good thing however, in the fact that they will deliver water at a constant pressure and allow the use of a very small pressure tank the same way a CSV does. It is just that when you have two ways to accomplish the same task, the simplest way is always the best way. A simple little valve (CSV) with only one moving part is going to cost much less and last much longer than any computerized VFD with thousands of electrical components. Plus using a CSV is much easier on the pump/motor than the pulsing power supplied and resonance frequencies created by a VFD. Pump manufacturers are in the business of making money selling pumps and VFD's. Why on earth would they even mention or condone a product that is disruptive to their industry because is cost very little and makes pumps last much longer than designed? Constant pressure is an excellent idea. And a CSV is a much better way to get it than a VFD.

[@bibitoigo2092]

What software that you use in the video?

[@cyclestopvalves8380]

It is a really old Flash animation program. It use to be an animation you could play with and see how the system works. Flash is no longer supported, which is why I had to make it into a video. I have someone working on a new animation, but it maybe a while.

[@deepakk1347]

01:06 That's why they use a tank If it didn't have a diaphragm then why would you even consider wasting you asset (time)

[@mailagaylord2843]

Hi, will the CSV work with any type pump?

[@cyclestopvalves8380]

Any pump with a centrifugal impeller. This includes submersible well pumps, jet pumps, mutil-stage booster pumps, turbine pumps, split case, and end suction centrifugal pumps. The only pumps a CSV will not work with are positive displacement pumps like piston, gear, and rod pumps like windmills.

[@MikeTuason]

How many horsepower of pump should I use with the CSV?

[@cyclestopvalves8380]

There are CSV's sized to work with any pump. Your pump is sized to the depth of the well, the pressure that you need, and how many GPM you want to use. Then the CSV is sized to fit the pump.

[@MikeTuason]

Thank you @@cyclestopvalves8380

[@cpufrost]

I'd love to install one but the poly pipe from my home to well is 45 years old and as I found out when digging down FOUR FEET to fix a leak, it's thin wall 100PSIG irrigation pipe! The NEXT time there's a leak I will hire a ditch witch and replace with proper 260PSIG 1 1/4" pipe and install a CSV set at 60 psig. My switch is set at 55/75 to keep my RO/DI watermaker happy. It's too large for a booster pump to be practical so there's that. Our Amtrol 87 gal tank only has about 22 gallons drawdown due to the higher pressure as well.

[@cyclestopvalves8380]

You probably only need 160# poly pipe. But they do make 250# if needed. First things first, you need new pipe. Then a CSV can hold a constant 70 PSI working with your 55/75 switch and 87 gallon tank. A constant 70 PSI will be much stronger than when cycling on and off between 55 and 75 as it is now.

[@cpufrost]

@@cyclestopvalves8380 Yes when there is a leak (and I'll know immediately as the system check valve is on the pump), I do plan on replacing the line. I want to overkill things as our soil is rocky and I believe that's where the problem lies. Even with careful backfilling, just don't want to deal with a break! I even thought of running conduit and pulling the pipe through that but that may be a bit much. The cycling is noticeable but not as bad as before when we had a 20 gallon tank with 4.8 gallon drawdown (55-75)! And if a toilet is flushed during a shower the water probably gets 15 degrees warmer for a few sec.
