I have a submersible sump pump, just under one year old, which recently has changed its behavior somewhat. By this I mean up until a few days ago, the sump pump would take seven seconds to fill and discharge once the float mechanism was activated. Now, the sump pump takes 14 seconds to fill and discharge once the float activates the switch.
Any thoughts on what might be contributing to this increased length of time?
Thanks,
