Water Pressure Control Switch Adjustment Range

How can I get a pressure switch that shuts off at a pressure above 50 psi?

I have an artiesan well 600 ft deep and would like to increase my water pressurs. I have a 1hp submersable pump with a 30 gal bladder tank.

Someone told me that they mfg a swith with a higher on/off pressure paramiter, is this true.

I currently have a swith that is a 30/50 on/off. Can I increase my pressure with a higher swith, thanks Ron. On 2014-07-16 by Ron Brown -

by (mod) - A 30/50 switch can be set higher but watch out for burst pipes or leaks

Ron,

Most water pressure control switches can be adjusted within a range, allowing you to up your cut-out and cut-in pressures above the factory 30/50 cut-in / cut-out pressures.

We explain how to do this

at WATER PRESSURE REGULATOR ADJUSTMENT

Watch out: However you need to watch out: setting the pressure too high may

1. cause the pump to run indefinitely if the pump can't reach the new high pressure

2. cause plumbing leaks

Be sure that your water pressure tank has an appropriate pressure-relief valve installed.

Question: pump used for lawn irrigation shuts down after a minute but I can force it to run.

I use my pump for irrigation for my lawn. Lately, The pump engages and provides enough pressure for the sprinkler heads to start.

After about 1 minute, the pressure switch cuts out and turns the pump off. If I go to the switch and hold up the lever on the left side, the pump engages again and holds pressure 30-40 psi for the remainder of the cycle. Bad switch? Any help is appreciated, thanks. - Dean G 8/20/11

Additionally, no adjustments have been made since the system was installed 4 years ago. It has been working fine until recently.

Question: irrigation system pump short cycling on and off

(Jan 24, 2014)Ron said:

Hi. After reading through all the info here, I am reasonably sure I could make whatever adjustment is necessary, assuming it is only an adjustment. I am just not sure of which adjustment to make. I do not know the size of my tank but it is 41" tall and 49" diameter.

The well runs only my irrigation system and a couple outside spigots. It is short cycling, assuming the guage is correct, in cuts in at 65 and out at 85. It does this as soon as I turn on a spigot or the sprinklers come on and keeps doing it every 3-5 seconds.

What I have done so far is: Check the cut in and cut out as mentioned above, made sure tank is not waterlogged(water level sounds as if it is about 1/3 or so up tank), checked the pressure in tank via valve on top at 37.5.

When I checked the pressure in tank, I did not drain anything, just simply checked with tire guage when pump was idle and water not running. Any advice what to do next would be very much appreciated. Thank you.

Hi Ron.

Take a look at the detailed instructions at

PUMP PRESSURE SWITCH STANDARD (PSI) SETTINGS

Basically you want the pressure tank (internal bladder type) pre-charge to be just a few psi below the cut-in pressure.

A pump that uses a cut-in and out of 68/85 psi is higher than we normally see in a residential application - one would worry about faucet drips and toilet leaks. Factory pressure settings are typically 20/40 or 30/50 psi. But for an irrigation system of unknown specs the pressures you cite may be fine.

The fact that your pump comes on immediately when you open a faucet and that it is short cycling - that is turning on and off rapidly means that the pressure tank is not doing its job. I'm guessing that if the tank is really not waterlogged then water entry into the tank may be blocked (e.g. by a collapsed tank bladder).

I suppose it's also possible that there is large diameter water piping and an under-sized pressure tank.

Short cycling is a different problem.

see WATER PUMP SHORT CYCLING : How to Diagnose "Water Pump Short Cycling" & Restore Air in a Building Water Tank" to read how to troubleshoot and fix that problem.

(Jan 24, 2014) rd36mnm

Thanks. What if I bump up the tank pressure to 60? Is that too much for the tank?

Reply:

Normally not. Check the specs on your tank, and be sure you have the required pressure relief valve installed too. A burst water tank can injure or even kill someone.

Pressure Control Switch Cut-in Adjustment

Comment: clarifying the differential nut adjustment range

7 March 2015 Andy said:
Near the top of this article, it says: 'Watch out! If you loosen this nut too much you can set the cut-off pressure below the cut-on pressure and the pump will turn on and run forever (or until it burns up.)'

This doesn't make sense. If you back the differential nut off 'too much', all that means is that the differential will be at its minimum which might cause short cycling. shortcycling is of course damaging too, but the pump can't fail to shut off if the main spring is set anywhere near the standard and all other things are normal. What am I not getting here?

Reply:

Thank you Andy, you're right and we're deleting the confusing text. We appreciate your careful eye and can use all the editing help we can get.

After adjusting nut #2, the smaller nut that in most of these controls adjusts the differential between cut-in and cut-out we kept this warning

Watch out: After adjusting nut#2 you may need to check the actual operating water pressures in your system and adjust nut#1 to be sure that you are not pushing the cut-out (upper pressure) so high that the water pump never turns off (dangerous).

As your comment points out, an additional caveat could be added: don't set the differential between cut-in and cut-out too close or the pump will short-cycle.

A different error would be to set the Nut #1, the larger adjustment, cut-out pressure too high. That's a common mistake that some folks make in trying to get the highest water pressure possible in their building. The result could indeed be a pump that never shuts off and that burns up.

 

Pressure Control Switch Differential Adjustment

Question: where is the differential adjustment nut

I do see the cut in big spring and nut, but i couldnt find the differential cut off nut, is this indicating that my pump is a very old one? - Old Pump 5/9/12

Reply:

Old Pump: sounds more as if you are describing a different type of pressure control switch that does not give all of the adjustments we describe - the switch may or may not be the same age as the pump itself.

Improper differential nut on pressure switch can cause short cycling of the water pump

In adjusting the pressure control switch differential nut#2, if you completely loosened the smaller nut #2 (differential adjustment) so that the pump differential between cut-in pressure and cut-out pressure is very small the water pump may short cycle on and off rapidly when water is being run in the building.

Re-adjust the pressure control switch.

SeeWATER PRESSURE CONTROL SWITCH ADJUSTMENTS

Improper differential nut setting on pressure control switch might also cause water pump to fail to shut off

Question: pump runs forever if the cut-out pressure is raised above 38 & differential set too low

I have a Goulds 1/2 hp J5 deep well pump with a 20 gal pressure tank. I am operating with a differential of 14 psi (20/34 cut-in/out).

Due to well limitations, the maximum pressure generated by the pump is 38 psi (pump runs forever if the cut-out pressure is raised above 38).

At this setting, the small nut is completely loosened.

I would like to operate at 24/34, but if I increase the cut-in pressure to 24 (large nut), then the cut-out pressure is also increased, and the pump runs forever (small nut still completely loose).

It seems that I am limited by the Goulds pressure control switch (which is attached to the pump and monitors the pressure by a plastic tube from the pump housing).

Any solution to this? It is a fairly new pump, so simply replacing the Goulds pressure conrol switch does not guarantee a solution, since the specs of the Goulds switch apparently do not allow one to operate with a cut-in/out differential of 10 psi. - Antony 9/14/12

Reply:

Anthony

You're right that the "range nut" (see article above) shifts the whole water pressure cut-in/cut-out range up or down, while the "differential nut" widens or narrows the cut-in to cut-out pressure gap.

I SPECULATE that Goulds and other water pump pressure control manufacturers don't allow the range width to be less than 10 psi because you'd find that when running water in the building the pump would be cycling on and off too rapidly.

You'd be better off to set the range so that the cut-in is at 20 psi, and then you can set the cut-out up to 34 psi

Low Water Pressure vs Pressure Control Switch Problems

On 2017-03-18 16:25:34.800026 by (mod) - clean faucet strainers, shower heads, washer hose screens if water pressure and flow are poor

Smart tip, Queenie.

Good tip for other readers: check those clogged faucet strainers and shower heads first. Another clog point is a small strainer found in the hose connector or at the hose connector fitting on both hot and cold water at washing machines.

Indeed anything that disturbs the well or plumbing system can send a shot of fresh debris that can clog faucets and strainers.

Once you've experienced the embarrassment of calling a plumber who just unscrews the faucet strainer and shakes out the dirt to show great water flow rate after that step, you won't forget it. At least that's my case.

On 2017-03-18 16:19:47.430151 by Missqueenie71

We recently had a slight freeze which caused a lack of water from the well. After the thaw out water pressure was horrible.

I found removing any faucet or incoming water lines to check for sediment build up. This (fortunately) solved almost all of our issues? Hope this is useful?

Question: low water pressure after replacing a pressure control switch

Replaced the pressure control switch on a 30/50 unit as well as pressure gauge. Water pressure has been very low since. Turns on at 30 and shuts off at 50 so its working. Had no water pressure problem before replacing. Replaced once we found a leak that tied back to the pressure switch. Do I need to adjust pressure on/off or is it the pump? - Eric Det 10/9/12

Reply:

Eric, if the pump turns on at 30 and off at 50 psi, then your pump, control, and waterpressure are normal. I suspect that we're mixing up water pressure - something you measure with a guage when no water is running - and water flow rate - how fast and hard does water come out of the tap.

Bad water flow rate (that people may indeed loosely call call "water pressure") can be caused by lots of different problems ranging from a poor well flow rate or clogged building piping to simply clogged strainers and shower heads.

Take a look at WATER PRESSURE DIAGNOSIS for WELLS for a procedure that should get to the bottom of this problem.

Question: Low water pressure in just some areas

(Aug 16, 2014) Greg

I hope this hasn't been answered already... I looked and couldn't find the answer...

The pressure in the kitchen is good (usually), but in the two bathrooms it is very low. I want it to be higher. Currently it seems the pressure cuts out around 60. Can I just increase it to 70 to help this problem, realizing it won't fix the problem entirely, or will that risk possibly doing some kind of damage to something else?

Thank you for any help!

Reply:

Greg

When pressure is good in some locations and bad at others, the best approach is to find and remove the blockage in the supply piping. Pushing the pressure to 70 psi may reduce the complaint, it won't address the cause, and it slightly increases the risk of fixture leaks.

(Aug 17, 2014) Anonymous

Thank you for the reply/help! I'll try to figure out the blockage, although not sure I'm going to be successful there.

Question: water pressure switch goes crazy clicking

We had someone install and new pressure switch on the water holding tank thought it was bad turns out that was not the problem. We ended up needing a new pump in the well and now have great water pressure. Water in this area is not a problem there is plenty of it. Our issue now is everytime you run water, flush a toilet etc the holding tank/pressure switch keeps clicking and the pressure gauge goes crazy and this keeps happening until the water is not in use anymore.

Water Pressure Too High: unsafe pressure switch or control settings

On 2016-10-10 by David

AUTHOR:Davidb (no email)
COMMENT: Do well pumps have safeguards for excessive head pressure?

If someone turns off the water supply line which feeds the supply tank, does the pump cut off or got into a bypass mode?

by (mod) - warning about excessive well or water pump pressures & mis-placed control valves

David,

Watch out: if some fool installs a shutoff valve between the pump outlet and the mounting point of the pressure control switch, closing that valve can cause the pump to continue to run until it is damaged, destsroyed, or worse, until high presusre blows a water line or water tank. A plumber in New Paltz, NY was killed by just this problem many years ago.

Residential pump controls include a pump CUT OUT setting that turns off the pump at a specified pressure measured typically at the water tank. In a proper installation the tank or water piping near the tank also include a pressure relief valve designed to open at a pressure below the tank's rated or burst pressure limit.

Head pressure inside the pump is not protected in a residential water pump.

If the outlet of a water pump is closed off there can be no trouble or big trouble: it depends on where the pressure switch pressure conducting tube is connected (to the pump housing vs. on water piping or at the pressure tank or at a tank tee) and where the shutoff valve is located.

The type of pump matters too: submersible in the well vs. above ground jet pump.

A submersible pump that is turned "on" and is isoltated from its pressure control switch and whose output is blocked by a control valve will probably blow a pipe, or more dangerous, it could blow the pressure tank. I know of a fatality involving just such a situation. Plumber working on pressure tank, pump in well is left on, valve is closed, tank bursts, plumber is killed by shrapnel.

Pump runs but will not hold pressure..what can I do. ? On 2016-12-19 by Lorraine

Last night I lost water pressure. Everything was fine while showering then it slowly lost pressure until it was basically just not coming out at all. However, if you go and reset the pump at the breaker box... you get the pressure back but it will happen again...

After about 3 or 4 minutes the pressure dissipates until practically gone. Any idea what could be causing this and how to fix/troubleshoot?? We can verify that the well pump has electricity running to it and we can watch the gauge go down as you use water, then watch it return after we reset the breaker.. any help would be appreciated! - 2016-11-11 by Jody Davis (jody.davis57@gmail.com)

Reply by (mod) - Water pressure takes too long to build-up or pump can't hold pressure

Steve and Lorraine, & Jody Look for:

1. Low pump voltage
2. Damaged pump motor or impeller assembly
3. Leaks in well piping
4. Low water in the well combined with a well tailpiece or other pump protection device

Sediment in the tank won't change building water pressure - that's created by the pump; but sediment in the tank may be a clue to other sediment clogs throughout the plumbing system.

On 2021-02-07 by WelcomedRain

Oof... Thanks... Since I draining the tank (when testing the air pressure in the tank, cut-in/cut-out pressure, etc.), the flow has definitely decreased. I'm thinking maybe tank sediment is to blame but could just be an exasperation of the flow issue that started the investigation. Thanks again.

On 2021-02-06 - by (mod) -

Normal people would call that weak water pressure but in fact since your pump is able to pump up to 62 PSI It's actually a flow problem. If the problem is the same for both hot and cold then there may be clogs in the cold supply to the building. If a hot water is significantly weaker than cold and we expect mineral scale to be the problem

On 2021-02-06 by WelcomedRain

Thanks very much. That is helpful. Since the general flow is weak at all fixtures, it seems not to be valve-fixture specific unless the prior owner reduced them all (I'll check that next).

Mostly, when I flush the toilet or have water running anywhere in the house, the other fixtures have especially weak flow. Thanks again.

On 2021-02-06 - by (mod) -

Welcomed

You can leave the pressure switch where it is if that works ok for you, but then you'd set the tank air pre-charge to 38 psi.

The procedure is at WATER TANK AIR, HOW TO ADD

It's causing a pump to cycle on and off rapidly that is most wearing; as long as the pump has no trouble reaching the cut-off pressure then it's ok to use the higher pressure setting.

But let's don't mix pressure and flow; if the actual flow rate at fixtures is weak then it could be that there are clogs in the piping system or a valve partly closed, or the well flow rate could be limited.

On 2021-02-06 by WelcomedRain

I purchased my home in May and it has low water pressure. The well's tank air pressure is currently 28psi.

Pump controls say the switch should be set to 30psi cut-in / 50psi cut-out (pump 3/4 hp); but the actual cut-in is set to 40psi and cut-out at 62psi.

To address the low pressure, should I reduce the settings back to the 30/50psi or increase the tank pressure to 38psi?

Would the differential (28psi tank pressure vs cut in psi set to 40) cause low water pressure? Will the switch settings being increased by 10psi (cut-in and cut-out) eventually cause an issue with the pump's or the tank's longevity? Thanks!

On 2021-01-27 - by (mod) -

That makes me suspect debris clogging of the pressure control switch or the tube that feeds water pressure to its sensor. Replace the switch and clean the tub or pipe.

On 2021-01-27 by cdl

Our residential well is possibly 700' deep. Pump control relay set 40/60. Usually works fine.
Problem: Pressure gauge sometimes continues slow rise after pump relay cuts out at 60psi. Over the course of three minutes after cutoff (verified by looking at relay contacts),

water pressure reading rises to 85 psi, and is correspondingly very high at faucets. Air valve at Welltrol pressure tank reads 87 psi air pressure.
Possible Cause : static head pressure from standing column after rain? Other causes? Fixes?

On 2020-11-02 - by (mod) - When I smacked the switch it would turn off however.

Kathy,

Usually when a pump will not turn off and cannot reach the cut-off pressure set on the pressure control switch the problem is not the switch but rather that the pump and water supply are not able to deliver that pressure. That's particularly true if you're cut off pressure is at a normal level of a say 40 or 50 psi.

Your comment "When I smacked the switch it would turn off however." suggests that the pressure control could be debris clogged. You should have that control replaced.

I am only able to speculate as I'm not on the scene possible that you are what are you straight exceeded the wills flow rate so the pump in fact simply couldn't get enough water to send into the pressure tank to reach the cut-off pressure. When you then leave the pump off for a time that gives your well a chance to recover and that in turn might allow the pump to operate normally.

So why don't you do an experiment letting the pump system rest for several hours or longer when it's misbehaving.

Then turn it back on to reach a cut off pressure I suspect the problem is in your well and the well flow rate and it would just be a waste of ex's time and energy to change switch.

On 2020-11-02 by Kathy

Just replaced a 30/50 switch because the 1 hp jet pump could not get above 37 and would not turn off. The pump, tank and pipe with foot valve are 1 year old. No problems until a few days ago, would not shut off. I was manually turning the pump on and off at the breaker. I am a senior lady living alone.

When I smacked the switch it would turn off however. Then the next day, it made it to 50 and turned off by itself. Yay! Fixed? No, a few hours later stuck at 37. My ex installed a new switch yesterday.

Adjusted the tank by a couple pounds (to 28) and it came on at 30 and off at 50. Only once though.

Now it is back to 30/37. No leaks, pressure stable unless using water. Ex wants to install a 20/40 switch. I don’t understand what this could be?

One day it pumps up to 50 and then only 37 with no stopping. This new switch doesn’t turn off when I try and flip the contacts either. I have to use the breaker to turn it off. Help!

Robert: a water pressure gauge installed literally anywhere on the water supply system will tell you the water pressure. Note that the pressure reading will vary but will be at its maximum when you are not running water and when the water pump has just turned itself off. Usually we install such a gauge right at the water tank.

You wouldn't use a "Reducing valve" at the pump; normally the water pressure boosting pump either has an adjustable output pressure right at the pump or if it's a conventional pump and pressure tank the pump pressure control switch sets the pressure range by turning the pump on and off appropriately.

Weird issue, water pressure was fairly constant in house until 5-6 days ago, then sudden drop off.

Had someone out to repair and said the galvanized line to the pressure switch was clogged and was replaced. Water is back to normal except in the morning when pressure is again low and we used to be able to shower and run the laundry machine at the same time but now the shower pressure is too low when the washer is running.

Also seems to be low after no water usage overnight but then improves after we start using it. Any tips or advice?
