Good day to all first off, I have a problem that happened all the sudden last night. My water pressure is very very low. The equipment that I have is a 3/4hp submersible in a 60ft deep well, a 44 gallon holding/pressure tank, I have very little pressure and the gauge showing about 20psi. I replaced the pressure switch with a new one and also replaced the control box with a new one, the pump will not turn on or off, cant hear the "clicking" sounds, what could possibly be the problem, thanks in advance, Matt.
