We recently lost water pressure from our submersible well. Upon inspection I found the pressure control switch to be completely blackened by soot. I assumed a bad switch, so I replaced it. The new switch cut in fine, but at cutout the switch started arcing rapidly, followed by a big flash and bang. So that's what happened to the old switch! Pressure settings are correct, bladder pressure is correct, tank has been drained, etc., but very rapid cycling at cutout pressure remains. Any ideas? Bad controller, low water, leak in pipe?
