My water source is a well and it was put in in 1999. This year the circuit breaker for the pump has started to shut off with no set pattern. I had someone over and he thought it was the pressure tank and we replaced it. But it is still shutting off at the breaker. It might go off several times a day, but lately just once per day with several days (two to three weeks in-between). I usually shock the system with chlorine to combat an iron bacterial oder problem once every month or two and it seems to occur right after that but that doesn't seem to be the only things setting it off. Sometimes it occurs the day after a heavy laundery day, but then again by flushing the toilet. As I said the frequency has no pattern.
Right now, I reset the breaker per occurrence and wait for the next time or until it shuts off completely. Any ideas?
