Pool pump mechanical timers. They are very reliable until they are not. In this case, the ON tab slipped off the wheel and moved all the way to 8:45PM. So the pool pump was basically running from 8:45PM to 6:45PM, 22 hours a day. They say moving water is happy water. I understand that but the owner is not so happy about the high utility bill.
