    i put a new pressure switch on my well and it worked fine a few times but stopped. If i push the points together, the pump comes on and the tank will fill up. if i use the water it will not turn on and i have to go back down the cellar and push and hold the points together again. This is the 2nd switch i put on in 5 days the first one fell apart. Are they just junk switches from lowes, name brand is proplumber. thats all they sell. Thanks for your time laurie

    Gary Slusser That's all folks!

    What type of pump do you have; a submersible in the well or a jet pump above ground?

    What was the original reason you replaced the first switch?

    Have you checked to see if the nipple or fitting the switch is installed on is blocked with rust or open so water can flow through it?

    i have a submersable pump. The points on the original switch fell apart. The switch was about eight years old. The 6 inch nipple is clear, when i connect the points together the water comes right in.
    thanks for the help

    Do you get water when you open a faucet?

    If so, when the pressure falls to the turn on the pump setting, do the contacts close and does the pump come on?

    If not, did you adjust the switch at all or not? You shouldn't have to, so if you did, adjust it back where it was.

    Otherwise you will have to tell me more details than you have or I can't help any more than I have, which so far is nothing.

    I get water from the faucet. when the pressure falls the switch doesnt turn on unless i go and hold the contacts together. then it will fill up and kick off and i let them go and use that water untill it runs out and i start all over again. the contacts will not close on there on. when i took off the old one, the water came shooting out of the pipe so i know that it isnt clogged. I didnt adjust the switch because the say it comes factory set for 30 / 60 . even if it came from the factory a little off it should not be able to drop all the way down to a few pounds. can the switch be bad.

    It should be a 30/50 switch, I've never heard of 30/60.

    Have you checked the air pressure in the tank, it may be too high. Or you could tighten the tall screws nut like 3 full turns and see what that does.

    If you check the pressure, you must do it with no water in the tank, and set the pressure to 29-28 psi.

    I got sick of playing with that pressure switch so I went to home depot and bought one from them. It looks like its made a little better. Anyway, i put it on and it works great. All that headach over a faulty switch. It is a 40-60. Im not very good at typing and i hit the wrong #. Thanks for all your time, I appreciated it , laurie

    Strange a new switch would be bad but now you fixed the problem.

    You check and adjust the air pressure in the tank now, you must do it with no water in the tank, and set the pressure to 39-38 psi.

    hi gary,
    you say to check the pressure in thed tank but you gave me 2 different answers. which one should it be , 29 or 39 and how would that effect things.

    It has to be 1-2 psi less than the turn the pump on setting of the switch. So 30/50 gets 29-28 and 40/60 gets 39-38 etc.. If use an air compressor, the air will be warm to hot and when it cools, the pressure will be less, or we could say there will be less air in the tank than there should be. Of course you do this with no water in the tank; drain it first.
