Excellent video. We had a new well pump installed a few years ago and the pressure just didn't seem right. So now I have it at 65/55. Perfect. I'm old and forget things quickly if I don't use them all the time. Audio and visuals were spot on. I don't see how you could have explained things better. It was a quick video not drawn out with useless information. I am now a new subscriber. Great job !!!!

I have a learning disability(Auditory processing disorder) that has been a real struggle my whole life. When you talk I hear you but it makes no sense and I don't create any imagery or understanding. It was extremely helpful how you touched each mechanical part when you spoke and turned them while you said what you were doing. Still even then I had to replay that several times to get the idea. At 6:30 you present the graphical of what you have said and that made sense in a split second. I really really appreciate these videos done this way.Puts me on the verge of tears to have had this made easy for me. For those that think people like me are just stupid it is actually most often the exact opposite . We are forced to think outside of the box that most people understand and that is a blessing in disguise.

@@pietpompiepompiepiet940 Check the pressure gauge and see what the cut-on and cut-off pressures are (like in the video above). If it's not that, maybe check the pressure in your pressure tank. It should have about 2 PSI less than the cut-on point I think?? My pump was doing something similar and I found out the pressure tank had zero pressure, I pumped it up with an air compressor and now the pump stays on longer.

[@virgil5361]

I will try to explain what I have been doing the past three months, I got my dad's old water pump out of the garage to attempt to hook up some sort of a constant water source to the cabin have here. The main problem with anything my dad had was that he was not able to read or write so anything he did that required some sort of reading or whatever always got messed up. The water pump will sometimes run up to 40 PSI and when the pressure falls to 30 PSI it will kick back on to build up, I have been trying to get it set to 50/30 meaning to build up to 50 and run at 30 to build pressure back up. But the main problem I am really having is the only source of water I have is a 55 gallon drum of water which in most cases runs out in a day so I have not been successful yet to get it dialed in properly for those settings. On the pressure switch on the adjustment poles I do see some white like some sort of marking which I had thought was a factory setting but when I have the nuts set to that marking it will not build up pressure or shut off, constantly runs and never builds pressure. Today I was able to adjust it to get up as high as 40 PSI but I like to get it up higher but I will not attempt to do it now until I can get more information on what i am doing.

Excellent how to video. Been out of work for several months and cash is tight, was hoping we wouldn't have to buy a new pump. This was a great help, our water pressure is excellent now! THANK YOU!!

[@omegamega1973]

Very professional explanation. I have lived in another place where I had installed a high and low level float switches connected to a relay to turn the pump on and off. The pump will not turn on so frequently but on the other hand we had very low pressure in the line. I was considering that turning the pump on and off so frequently would not be good for the motor. The pump turns on every time you flush the comode or open any faucet.

[@DizzLexic]

Thanks for the clear demonstration. at 5:12 .. it actually took it to around 70psi not 66 .... so looks like each full turn on either nut adjusts it up or down by 2-3psi as stated in the manual.

[@JamesZ1025]

Exactly what I needed, had new pump installed and installer said had too much air in tank. Lost water pressure once he let out air. my 40/60 was working at 30/50 :-( By far, the best explanation of how a pressure switch works that I've seen.

[@eddiedeleon2425]

there are many variables

[@RickyG1953]

If you change the pressure settings adjust the well tank precharge air pressure to 2 psi lower than the cut in of the pressure switch. For preventative maintenance annually check the precharge and adjust it if necessary. The measurement is made with the water pressure at zero.

I have low water pressure in my home. I have a 20/40 pressure switch, 220 gal pressure tank and 5hp (63gpm) pump. The pump kicks on at 15psi and off at 40psi, runs about 3.5 mins to fill the tank (formerly used to run a 2" irrigation system.) The water line into the tank has a valve stem (similar to automotive type) that leaks water when the pump is on, it also blows (or sucks?) air for a couple minutes after the pump shuts off. I need to adjust the pressure switch to turn on at higher pressure and replace the valve core in the valve stem?

Thanks Chris, this was very helpful! Your videos are always clear and easy to understand. I have a pressure switch that’s come out of adjustment over the years. I’ve struggled trying to adjust these switches before by trial & error, so this took the guesswork out & I’m now confident I can go out & get this thing re-adjusted!

[@HauntedBranch]

How did the re-adjusted go ? I'm scared to try on our pressure switch.

[@TomWylie]

@@HauntedBranch I didn’t actually end up adjusting it because I found the contact points were badly pitted. I cleaned them up the best I could, but it still kept working very inconsistently (not allowing the pump to shutoff). So I just replaced the entire pressure switch, which went very smoothly and now our system is working perfectly! I also found the pressure gauge to be off by 10psi (I tested with a gauge that connects to a garden hose thread, and put it on a hydrant to compare against the existing gauge). Glad I did, because I discovered that the new pressure switch was working perfectly (pump on at 40psi, off at 60psi, which is what it was set to do) even though the old installed gauge reads 50-70psi operating range. Now that I know that, I’m just leaving the old gauge in place until I re-plumb the entire system when I remodel the pump house when I get to it. Good luck with yours!

[@YouToobeism]

Nice, well-done video on pressure switches. Nice to know the 2-3 turns per 2 psi rule of thumb for the range. However for the cut-out adjustment, the new cut-oui pressure shown at 5:20 or so is just above 70 psi, not 66 psi.

[@josephdurso297]

I think you did not mention that before changing the psi cut-on setting, if there is a bladder tank, you should change air pressure in tank to be about 2 psi below the new cut-on setting. The water pressure should be zero when you check the tank air pressue. The spring adjustments you explained were very helpful. Thanks.

[@kevinfeldhaus8238]

😊😅😊😅a

[@blitheringrando1410]

Great point! Since the bladder tank and switch have to be 2 psi apart, it would be important to check your tank pressure before you assume the switch needs adjusting.

Thanks for a very informative and easy to understand video. Factory setting for my pump is 30/50. I am currently at 40/60, but I would still like more water pressure. Can I safely go to 50/70? As seen in other answers, should I turn up 1-2 full turns to see if my pump can build the pressure? Thanks!

[@suprabunny]

Okay, this video is the only one on KZbin that's given me any degree of hope in the dilemma I'm having (or rather, my girlfriend). I've watched this video 7 or 8 times now just to be sure I haven't missed anything. My gfs pressure tank is in her basement, so from what I've gathered from this and other videos probably 40/60 would be the better setting as her pressure is GOD AWFUL! Rain has more psi than her shower. I check the pressure within the tank (membrane) it was at 18..... So I pumped it up to 38psi (since I wanted the 40/60 setting). I turned the cut-out nutt clockwise a fair amount hoping it would show me some kind of change. The best I can see is we've gone from 10/30 (yes, it was that bad) to 20/40, but I cannot seem to get it go above that. That spring is quite compressed as I'm not sure it should be screwed down that low to only achieve 20/40. Before I start cranking the spring any lower, I need help, I dont want to blow this tank up. The COLD water does have a noticeable difference, however once the pressure gets on the lower end, its VERY noticeable, the HOT water barely drips from the taps, any tap at all. This is a boiler system setup, so am I missing something else that has an effect on shower/sink psi?

[@RCworstwater]

First thing you should do is replace that old pressure switch. If you're sure her pump is able to produce enough pressure to run 40/60 then a new switch might solve all your problems (if you're not sure find the model and give us a call). If that doesn't fix the issue then you need to trace the hot water line and see what it's going through. I'm not too familiar with boilers, but if that's the only thing in-line with the hot water that must be the culprit. See if you can find an owner's manual for yours to troubleshoot. Here's a link to the pressure switches on our www.rcworst.com/Pressure-Switches-c172.html

[@jackb1803]

Besides replacing the pressure switch, I'd also replace the gauge. I've had bad gauges that showed too low of a pressure or none at all. You will need an accurate gauge if you plan to change the settings on the pressure switch. For the boiler, it might be clogged with calcium deposits or rust. A flushing might help. Also check to see the aerator on the faucet is not clogged. Finally I had to re-pipe a house because the galvanized pipes where all clogged with rust.

Excellent tutorial. It clears the "mystery" of pressure switches. I have a question thought. My guess is the previous home owner messed with the switch before watching your video. I have a Cut-on=20 and a CUT-OFF: 58. This is a two story home and the CUT-ON of 20 is not enough to maintain good pressure in the upper showers. and I'd like to bring it back to the factory setting of 30/50. My guess is to adjust or lower the CUT-OFF to 40 and the adjust or raise the RANGE to end up at 30/50 TO 30/55. Does this makes sense to you or do you have another suggestion? Highly appreciate your input.

You're spot on in what you need to do! Give us a call if you need any more assistance: 855.329.4519

[@jackb1803]

Since the adjustment is messed up, I'd turn down the differential first - no need to be exact. Then adjust the main screw to establish your cut-in pressure. Then go back to the differential screw to adjust your cut-out pressure. After all of this, you will likely need to adjust the air in your pressure tank.

Now I'm starting the well up for this year and the needle is at "50" and the pump runs up to "100" before I freak out and turn the power off. I bought a replacement but am curious about resetting this one that has the "50" starting point. There are 2 phillips head screws on the back and am wondering if these are needle adjusting screws? Again I have a new one but if this happens for other folks... Many thanks from Idaho.

This is the only video in internet that i learned how to adjust pressure switch and tank now after i set to 40/60 and 38 psi tank Thank you million time

[@robg2049]

Great video it told me exactly what I needed to know. Done very well too. Thank You very much. I'm going to subscribe.

[@mikeinigo2728]

Excellent video. Helped me diagnose and solve our water problem. You are a true asset to all.

[@RCworstwater]

Thanks for the kind words!

[@thefarsideoftherails7415]

Thanks for the video Chris now I'm tempted to try to raise the range but I'm not sure if my pump can handle the 40/60. I rented this property before I bought it my landlord had to replace the submersible pump and he's really cheap so I think he drove 200 miles and bought some pump at Lowe's and had a well guy install it. I think the old pump was a 40/60. Split. My question to you is if I raise the range too high and the pump doesn't have enough balls it will just continue to run and not cut out❓ maybe I should try raising the range to 35 cut in and see what happens. I will also adjust my pressure tank to 33 Psi. Nevertheless I'll wait for your response before I waste a bunch of time. Thank you again for the video have a great day👍

[@RCworstwater]

Thanks for the question! You are correct, if the pressure is adjusted above what the pump can build it will not be able to reach the "cut off" pressure to turn itself off. The best approach would be to increase it in intervals of 1-2 full rotations and cycle the pump to see if it can build to the new pressure. When you're done adjusting empty the system and set pressure in the tank. If you'd like to discuss this at depth contact us by phone or email.

You can also turn down the differential. So changing it from 20 to 15 may allow your pump to get to the cutoff pressure point, but it will cause it to cycle more frequently.

[@billyreynolds1013]

After many years of trying to understand pressure switches this video was very good in explaining how to adjust the range of the pressure switch, just one question, if I change the range on pressure switch from 30-50 up to 40-60 do I also have to increase the pressure in the pressure vessel from 28ib to 38ib? Thanks again.

[@RCworstwater]

Yes, you will need to adjust the tank air pressure to 2 psi below the cut in pressure.

[@claragary]

Thanks, very good explanation!

[@jollyharami816]

Good

[@myfreedomblueprint]

This was very clear and I appreciate the multiple ways and pictures used to explain the process. Thank you for this.

[@RCworstwater]

Glad it was helpful!

[@codanni]

I have 2 pressure tanks, Aqua Air V60 & Gould V200, both charged at 38 psi. I removed a retention tank from the system and now the new pressure switch will not turn off, its a 40/60 switch and I manually have to turn pump off at 80 psi to be safe. I adjusted cut out with no success on the new switch. Changed the new switch back to the old working switch (no adjustments) and still the same. Any suggestions?

[@RCworstwater]

Just got off the phone with Danni, for everyone else reading this: we believe it is sediment/calcium buildup in the piping that the pressure switch is connected to.

[@HauntedBranch]

Did you find out what was wrong ?

[@codanni]

I did find out thank you 🙂

[@kolankprof]

Excellent Video ... great close ups of the two adjustment screws and very easy to understand summary slides. Thanks for sharing your knowledge on this topic!

[@stephenzies8867]

Great Video. Thank You Very Much . Very Helpful.

[@GarethJones-vf2st]

Thanks for making the video - very helpful... the instructions on my pump gave no guidance on how to change the pressure switch, so this is invaluable!

[@RCworstwater]

Glad it helped

[@ItAintMeBabe99]

Very excellent explanation! Thanks for sharing !

[@michaelj1232]

great video , i have a well pump for my irrigation system, in one zone the pump short cycles at times, which adjustment would i need to adjust, the pump is 30 /50 ????

[@ebieinstein]

Thank you. This was so helpful

[@bluesky90010]

This video is from someone who knows not someone who has an idea.Thanks.

[@wallystewart1979]

great video love the way you explained it

[@ignitiusmwale7069]

thanx for the video ...buh I think range bolt does not alter the range of cut off and cut on buh raises or lowers the cut on and cut off points with the range constant and the differential alters the range since it changes one value either cut off or cut on

[@snutz213]

When you said it got up to "66", it was actually 70-71 so that would affect the math you had on the amount of turns on the nut. Just an fyi.

[@chrisworst7315]

I did misread the gauge there, good call. The differential switch is a much lighter spring than the range adjustment so it does not often line up perfectly within the 2-3 psi mark. Additionally, if you ever need to lower the differential I recommend removing the nut completely and stretching the spring out a little to give it some tension when you reapply the nut.

[@stfuplsok]

snutz213 a* fyi

[@hikerdude5265]

This is what I was looking for; second floor pressure was the issue. Copper pipe house with a 40-60 pressure gauge and looking to add another 10 psi. I also learned that after it's set to 50-70, you must set your bladder tank pressure to 2psi less than pump engage psi, i.e., 50psi kicking on is 48 bladder (Bladder is measured at null water pressure state). Correct me if I'm wrong but I ran this and it seemed to work.

[@drum6560]

‘This is an outstanding video!

[@doug900S]

My pump is set to to 30 to 70 psi. Looks like I need to back off on the range trim adjustment, then adjust the center adjustment, to set 40 to 60 psi That should take care of the sudden drop in pressure that I am getting, even after adjusting the air bladder to 2psi below current pressure. Nice video!

[@RCworstwater]

Thanks for the comment and for watching! :)

[@donniecorrigan8519]

Great Video, well explained/

[@hokehinson5987]

Does the differential pressure always need to be 20 lbs? Can one adjust to say 25-55?

[@MM-kr2ih]

thanks a lot, u really helped me adjust the pressure very easily.

[@jeflorezkko]

Excelente video ,thanks.I would like to know if is enough a pump 3/4 HP for get this pressure with a presure switch 40-60 PSI

[@RCworstwater]

What is the model of your pump?

[@celtichongy]

Excellent, very helpful info.

[@fatemehg4083]

Thanks for your good video. Is it necessary to use a pipe to install the key in 5 ways?

[@norsefan3276]

don't forget to increase the pressure in your tank if you increase the cut in pressure!

[@dannyrenkiewicz9551]

Good thought.

[@tonu115]

Thank you!!! I was scratching my head wondering how I can get my threshold to be tighter. I’m having a pump problem so I need 35-45 range to get us by until we get a new pump!

[@bobbyleblanc6112]

Great video! Had a new well pump installed last year and pressure hasn't been right since. I work away but due to covid finally annoyed me enough to want to fix it. Video was spot on, saved me a call to a plumber.

[@RCworstwater]

Nice work!

[@joe96787]

we got a new pressure switch last summer 2018 and was fine till now . It doesn't turn on till it's down to 20psi and dose not turn off at all . Plus the smaller switch ( the cut off ) dose nothing at all . I've turned it all the way down and all the way off and it dose nothing .

[@JRPittman]

GhettoJoe check the line feeding the switch. If it is clogged with mineral deposits the switch an not sense the pressure in the system and will not work properly. It is not uncommon for minerals to form here the tubing fitting or nipple is screwed into the body of the pump on et or shallow well pumps on submersibles the nipple Nader the switch can become clogged, especially with a galvanized nipple... change that to a brass nipple; brass doesn’t build mineral deposits as bad

[@dino246gts]

Thanks a lot, so basically, the pressure switch for the water pump serving for the car engine works automatically up and down, right ?

[@paranormalnightmaretv]

Great Video thanks for making it. Very informative on how to make the adjustments.
