Well Pump & Pressure Tank help needed

[buckle97]

I need some help with my well and I am a complete novice about them. I purchased this house last summer and the well worked fine. It would cut on around 30 psi and cut off around 50 psi. I turned off the breaker to the well and opened up all the faucets and left them this way for about two months. Now when I turn on the breaker the pump kicks on and the pressure, according to the gauge mounted on the tank, just keeps rising to above 90 psi and won't cut off until I turn off the breaker. With the power off and the all faucets open, the mounted gauge reads 50 psi. I had an extra square d pressure switch and put it on but it does the same thing.

Questions:
What should the pressure gauge read when there is no water in the tank?
If 50 psi is too much, how do I release the air pressure?
Any ideas what the problem could be?

Thanks in advance.

It won't have anything to do with the breaker. From what you wrote the breaker is working the way it should, applies power when ON, stops power when OFF. Your problem is in your pressure switch.

Are both pressure switches doing the same thing (reading 90 psi) or is it just your guage that is reading 90psi and the pump is not really getting to the actual 50 psi it needs to see to open up? If the guage is at 50psi and there is no pressure on the system then probably 90psi is incorrect and probably only actually only 40psi, not enough to shut off the pump. When to gauge reads 90psi does the water seem excessively overpowering? Try replacing the guage and see what happens.

Your problem is in your pressure switch.

I have two pressure switches and they both are doing the same thing. The one I put on was new in the box factory set to 30 / 50.

Do you have a bladder tank? If so, you release all the water, and add air to the bladder tank I believe 2 lbs below the cut on pressure. For the high setting, adjust it to cut off at 50 pi.

Ref data

Set the air pressure in the empty water tank to 2 psi below the well pump pressure switch cut-in pressure. Bleed air pressure out of the water tank, or add air pressure into the water tank, until the tank pressure. For example, if your well pump pressure control switch is set to "cut in" (start pumping water from the well) at 30 psi, then set the pressure tank to (30 - 2) = 28 psi.

There is usually a 20 lb difference between cut on, and cut off pressure on the pressure switch, such as a 20-40, 30-50, or 40 60.

Should the mounted gauge read 0 psi when the faucets are open? Right now it reads 50 psi and never gets below that even with the faucets open and the breaker off. The water pressure does seem really high when it reads 90 psi but it might just be in my mind.

How do I tell if I have a bladder tank?

Like this or smaller. On the top, there will be a air valve for testing or refilling. If the bladder will not hold the air, then a new bladder tank is required. Some tanks have a bladder that can be replaced.

If the gage reads any pressure with all valves open and the breaker off, then the gage is bad. They are only about $6.95

My tank looks similar, but I don't recall seeing an air valve.

If the gage reads any pressure with all valves open and the breaker off, then the gage is bad. They are only about $6.95

I'm hoping it's the guage; I'll stop on my way home today and buy one and see if that is the problem. Thanks!
