My well was working fine; new pump, piping, pressure switch, control box, and breaker. I did manage to reuse the wiring!!
I installed a SandMaster centrifugal filter today, between the pump and the tank, as suggested, and when I flipped the breaker to start everything up, the pressure switch constantly clicks on/off.
The filter is full of water at this time, with lots of pressure if I open the dump valve, but there is no water going to the tank itself. I did get some water at the house, but was afraid to leave everything going for fear of burning up that new pump motor.
I have not checked the bladder pressure on the tank (but it was working fine beforehand).
Could the pressure switch be set too low now for the extra "push" needed to get through the filter? Pressure loss is supposed to be a steady 3-5psi, if I remember correctly.
For now, I'm going to install a bypass around the filter because I need a shower (!!) but I can't understand what is wrong, other than it being a pressure problem.
The filter was sized according to flow, and as near as I can tell I have done everything correct.
Any suggestions, anyone??
