well pump- pressure switch question

Posted by kendoo (My Page) on

I just replaced my pressure switch with a new square D 40-60 switch. When I turned on the power the switch did not cutoff at 60psi. It went over 100psi. The last switch was acting flakey with high pressures that I could not lower with the adjustments on the switch. I have no idea why I am having this issue. I verified the high pressure with a hand guage on the pressure tank. Why would 2 switches not cutoff at the high limit?? Thanks

Have you checked to make sure the pressure line is not kinked or clogged? It might be clogged at the tank connection.

I'm going to take it all apart and check again. The cut in pressure is suppose to be 40psi. I had my tank set at 38psi, yet the pressure still goes to zero for a few seconds before the switch turns the well pump on. I even lowered the tank down to 30 psi hoping the pump would kick on before all loss of luck. This baffles me.

All fixed- Thanks Randy. The pressure switch is thread on a little 2" copper pipe that was completely clogged. Wasted $20 on a new switch, but the education is priceless!!

I have seen that before myself... sorry about the switch, but you know that part is new now.

Thanks for posting back and saying how it was resolved.
