Claims " low pressure cut-off at 40 PSI" but that cannot be true. HOW LOW does the INPUT pressure prevent pump from working?

OK the way it works is= it goes in your main water line in parallel and you need a pressure gauge also so you can see what the pressure is and if it says 40-60 what that means is the pump will come on and pump the pressure up in the line with all water flow shut off in your house and it will pump up to 60 lbs and the pump will shut off then wihen you use the water the pressure will start droping and when it gets to 40 lbs the pump will come on and pump up to 60 lbs and the pump will shut off. There are two different kinds of these switches the one I just described and the one that ends in 24M4CP. This one works the same but if the pressure goes below the 40 lbs it dosen't keep pumping it shuts the pump off. You have to manually reset it with the little lever on the switch. The advantage to this one is if you pump your well dry the pressure will go below 40 and the pump will shut off and save your pump from burning up. The bad part is (Like with me, )Our power goes off in the winter a lot in snow storms and if its off long enough to loose pressure I have to walk up in the cold and snow to the well house and manually turn the pump back on. Both of these switches look the same except the on has a little lever sticking out the side of the switch for the reset. You should also have a pressure tank also in parallel with the main line and it works like a capacitor to smooth out the pressure drops. Hope this helps

I got mine working from 21 to 33psi aprox and it cut below 10 psi. Is easy to set it up

I agree it has to be lower than 40 psi. Probably between 20 and 30 PSA it is designed to protect the pump if the water supply dries up.

if it's working right, it should pressurize it less than a minute. I've had major issues with two of these pumps losing the ability to come to pressure. Haven't had much satisfaction with repair or customer service. I would advise against this pump if you haven't already purchased one.

This switch is adjustable. You can set the cut-in and cut-out pressures separately. It's set at the factory for 40/60, but you can make adjustments internally to lower (and I think higher) pressures, e.g., 30/50. (Note: I haven't done this and I don't work for the company and accept no liability.) The Square D web site is not very helpful, but the web site for Pumptrol (the Square D pressure switch brand) has a lot of info. If you look up the 9013 series of pressure switches, you'll probably find the info you're looking for.

The pressure rating far exceeds your pump. The connector is standard. At worst you would have to add an adaptor.

the pressure will not reduce unless the capacity of the pump is not sufficient. most of the time these pumps are way more efficient than the size of the hose so I wouldn't worry about it

Hmmm.. Did you know this compressor is sold all over the internet? Many different brand names but the same compressor. I just bought mine so I can't confirm the complaints, but it seems to me that there is a tank associated with this one. It's supposed to cut off after the pressure reaches the limit that is set. If you don't know anything about compressors, you should really read up on them before operating.

This pump simply doubles the input pressure. In my case, 40psi becomes 80psi.

Hi, Im not sure what the pressure is on either side, we have it to step up low pressure coming in. there has never been a problem with to much press. on the out side, this is the second pump we have used over several years.

Okay the pressure switch wall shut the pump down about 65 pounds also to start to pump it has to see flow considerable amount of flow when you open up the Fossett it will sometimes drop down the 40 before the pump kicked so very smooth then whenever you shut the faucet off it will shut the pump down and about Katie three seconds

I have a zone controller that turns the pump on and shuts it off based off the time period I set. I do not think it has a pressure switch, though I may be wrong. Research the specs on it. Hope this helps!

this is not a good choice if you put the pump 200 feet down, as the pump will stall (zero flow) at 221 feet of head.Subtract your setting depth from the 'shutoff head', and multiply the difference by 0.433 to get the maximum pressure at the tank.Set your cutoff switch somewhat below that max pressure or the pump will run continuously....

The PSI rating is not stated, neither in the manual or on the unit. The pump does however has a pressure switch that shuts the pump of when the flow is zero.

This pump works fine as an inline pressure booster. As far as a pressure shut off, I believe the only factors are; it is not self priming, and if the start up head pressure is to high the pump is unable to perform.

One of your pumping pistons isn't re-extending for the next pump and so it's only pumping at half pressure. That's how mine died, I haven't figure out a fix yet.

That's a tough one. Seems I have to actually start using slight force at about 30 PSI. My tires need 50, so from 30 to 50 it gets a bit tiring. Still not hard, just a lot of pumping. Also seems the faster I pump the better it works. Slow and steady doesn't seem to move the gauge.

Line vs. load- I usually use the center two screws as load and the outer two as line in. You are getting power to the pump or it wouldn't be working. Try backing the cut out control nut out to reduce pressure "the one with the short spring located off center". If all else fails remove the switch and unscrew the backing plate, remove the diaphragm. You can test the switch manually by pressing on the center of the mechanism with your thumbs. Also while you have it apart look through the inlet pipe. The actual water inlet hole is quite small and can become clogged. Reassembly doesn't require any kind of sealant.

I can tell you what it does for me. I have about 30 psi without the pump. With the pump I get 70 psi. I have the pump before the ro unit and I measured the pressure after the ro unit
