Well pump pressure switch
SE United States.
My parents have a well pump that stays under a shelter, but I have had to put 3 different pressure switches on in a year and a half. My dad always wants the mechanical with contacts, despite me telling him there are may be other options.
My only day off this week and they called me today to tell me it's broken again. Before I head out and repeat this process AGAIN, is there something that could be causing them to fail so quickly?
It's covered. Out of the weather. The only thing I can think of is wiring...it's got braided wire running from the house to the pumphouse but Romex from the feed line to the pump. I've wondered if the voltage could be dropping and messing them up early.
Any thoughts or advice?
