Hi, just joined today and excited to be a part of this.
I have a sump pump, new within a year, and the float switch was getting caught against something so I adjusted it so it moves freely. When I first looked at it, lifting the switch I could hear the ball inside the switch "flop over" to complete the circuit, but the pump was only humming, not pumping. After playing with it a number of times the pump finally sucked all the water out. First time ever seeing one of these work, very fast. So I adjusted the float switch, tested fill/empty/fill/empty 5 times and ran every time.
1 week later I check water level and operation of the float switch - AGAIN, I only hear humming, but it is not pumping the water. It is like the pump is not getting enough voltage, or some contacts have become resistive. I do have a multimeter and electrical is my forte. Has anyone had this humming before? Is the problem likely switch, or pump?
