If somebody really wants to understand the CSV And what the true implications are you need to on A data recorder and log use use of the motor And how much draw it is taking over a 24 hour period with and without a CSV. That’s the only true comparison

outstanding video

Just buy a variable resistor and use your vary the speed. Can’t sleep with the light bulbs just as the noise Did.

This explains why I can cut straight with a circular saw! Thanks

My pump pumps water at the well head at 25 gallons per minute with no tank with a 240 hook up. And t fills my 35 gallon bladder tank in about 1.5 minutes. So my question is how does this thing work? There's no wires so it can't slow the pump down. My pump bypass pressure is 80 lbs so it can't be pumping through the bypass valve at the pump if the gauge says 50 lbs. And if I install one, and it's only supplying a demand of 1.5 gallons per minute, wouldn't that take about 15 minutes to fill my pressure tank back up? And if the pump is backing up through the 80 lbs pressure bypass, wouldn't that put an extreme amount of pressure on the motor? None of this makes sense.

I'd like to know what happens to the rest of the water being pumped. My pump has an 80 lbs bypass. This whole system sounds shady.

VFD’s are very expensive! CSV valves work great, I hav had multiple in use for over 15 years. I am sorry, your information is very wrong.

Thank YOU!!!

Conclusion: Old style SS tank is still the best. But its up to you to try new style 😂

For a true comparison, you would have to add all of these scenarios together. Nobody that turns on their tap 20 times using 1 gallon of water that’s ridiculous. Probably half of those maybe 1 gallon. So what you need to do is add all your scenarios together and average it out to see if the advantage of constant pressure outweighs whatever excess energy or pump cycling is. In the end I think you were probably even.

You are incorrect in your assessment as your simulation of a restricted motor does not translate into a motor that is attached to an impeller that moves water. The motor is only receiving the resistance from the impellers. If you shut the flow of water, then no work is being done. Thus the motor will spin faster and do less work, which will equate to less power consumption. As an example, it’s the exact same scenario as when you put your hand over the end of the vacuum and the motor speeds up. The vacuum is not pulling a vacuum that’s the motor is doing less work, which means less electricity being used.

Thanks a lot Larry! I couldn't figure it out myself.you help me a big time!

Thanks for sharing.

I don't know if this will help you Professor but with respect to string tension if the tension is low the strings will have a trampoline effect means the ball will have more pace (faster). Now when the strings have more tension the pace will be less pace (slower) With this understanding the balls could work the same way. In which case the ball that's newly open is more stable and that's what we call is an old ball is not deflated but more inconsistent in its bounce.

Your examples are way off base.

Best, most informative video on this subject. Hands down. Just inherited a lake property with a shallow well and need to get up to speed on that whole system. Thank you for all the good information.

Sometimes defensive driving is a bad things as we become more conscious than required, our focus is just on one thing but it increases the error possibility (especially true for those who can't handle stressful situations) as focus consumes a lot of energy and it also slows down our decision making capability.

Silly me i didn't know there's such as bladder tank thing. But thank you for explaining comparison. But what i did is with our stainless tank is i put tire valve on top then i just inflate it when ever the air inside is depleted to avoid draining the tank completely.

Lower the value of the capacitor it will works

Everyday Gold is a dark horse, i found them comparable to Rayovac and Duracell for its price

Love your stuff but this one didn't age well as the vaccine isn't really a vaccine and now everything is being labeled "long covid" when in fact it is vaccine related.

Excellent video deserves to be subscribed too. thank you.

Thank you! You saved me the world of frustration!

If we have a positive suction in the fire system(as an example, if we take the sea water as the main water supply for the fire system and the pumps are located at the 10m under the sea level) In this case, do we really need any type pressure tank? Could you pls reply to this? Anf Thank you for the video, very informative.

More less how many minutes do u spend ironing on each side cause my iron doesn’t have a heat light :(

Thank you so much Larry for your scientific method for underwear stretching. You like a mad scientist without the mad part...LoL. I have subscribed to your channel and I am going to see what other amazing secrets of the in-home & improvised scientist methodology/inventor like ingenuity that is available for mastering. Take care and happy labour day Larry!

Hi ​ @LarryElterman - solutions that use PRV, don't they require and expansion tank after PRV as PRV also acts as a check valve and creates closed system?

This video was made on my new computer, I had no proper software, I used Amcap, a free and low tech program. The voice did not even sync up, but hey, just treat it as an audio. Nothing to see anyhow haha. The quality of this video is embarrassing, but since I expect to make no money from it I will not bother to fix it.

Just add some heat with incandescent light bulbs?

L0L... You complain about him "picking" special pumps... then layout an unrealistic "water storage" system WITH NO WELL!

Thanks i enjoyed from iraqi kurdistan Thus video was one of the rarest vudeo

Lengthy but full details clearly explained. Worth every minute. Thanks a ton, @LarryElterman 👌👍

that table is SO shiny

Good sir, you are incredible at explanations. This is the first video I watched from your channel and you did a fantastic job! Thank you for the time you spent making this video.

Very informative. Thank you!

Test it or just try to pick something up

very nice!

Aggassi just used a fat rubber band with a single one half hitch. Pete used an a rubber grommet from fuse box. I use a pony tail hair tie.

Thank you! Very informative. I am about to install a new water well system and after watching your video I will not be getting a CSV as I was originally planning.

Also, why not just wire in a rheostat?

Does anybody know if it makes sense to take a 220 to 110 step down transformer to take 110v and step it down to 55 volts? In other words, if you fed 110v into a 220v step down transformer (a copper coil one in particular), would you get 55v out - and not create some other problem/hazard.

In your efficiency calculation you did not include electrical costs for pump. If your draw down is double with the diaphragm tank (for example) the pump would be activated half the time. This is an important consideration when determining total cost of ownership, not to mention wear and tear on the pump.

I went through the stages of grief because of this box cutter then finally my persistence worked 🤣

Interesting going to try this or something like it. Thank you so much.

What about leaving it on a stick with max stretch for few days instead of ironing?

Thanks alot..very helpful

I've only made it to #7 and your #7 and #8 reasons to not buy are exactly why you should buy a CSV. Every pump manufacturer will tell you that their pumps are designed to run 24/7 and you will get the best life out of pump the longer it runs because the starting and stopping action is what ruins a pump. Yes running a pump longer does use more power it's just not as much as you think and probably pennies a day at best. When a pump see's high pressure it actually reduces amp draw, so the pump isn't actually running at say the full 1/2hp, it's effective hp is now say 1/4hp which will draw less power. You should learn more about electric motors before making comments about them. Now a CSV isn't for every circumstance. They are designed for people who have irrigation systems or use a high amount of water with a much to small pressure tank.

Excellent job well done 😊

thank you

Thanks for the info. I've been trying to slow down antique electric fans that were designed to run on closer to 100 V instead of the 110 - 120 of today's lines. They do make transformers to run Japanese appliances (100V) on North American voltage and it works great for my 1916 12" GE but they are large and expensive. I am currently trying to slow down a tiny 6" GE from the 1920s and I'm looking for a simple, small and cost effective way to do so. I'll have to see if I can incorporate this method. I am curious why your house runs on 220V when you sound like an american and have american style plugs and outlets? I would expect 220V only for your oven and dryer.
