So this is interesting. I've been waiting to try hitting the pump but for the last three days the pump has started spontaneously. The only difference is that I set the pump to start a few hours later in the day. However, today I returned home from work to find the pump off. I took the opportunity to beat the living hell out of the pump while it was humming. Unfortunately, the pump kept humming and flipped the circuit breaker off 3 times before finally starting. Any ideas now?
