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
Any thoughts on what might be contributing to this increased length of
Could be that some crud has built up inside the pump over time, and is
now clogging up the water's pathway. If it looks like a simple task to
take apart the pump housing, you can have a look inside it you'll
easily see the crud if that's the problem.
Can't say why the delay. I have never seen a sump pump that didn't
begin pumping instantly when the switch activates. True, it might take
a few seconds for the water to reach the drain pipe outlet but that is
a function of filling the pipe up first. Now if that is what you are
referring to, then yes, it is a crud up problem.
It is still pumping once the float mechanism activates the switch,
however the total time for it to complete its activity (until the pump
shuts off) has increased.
Thanks for your thoughts and the other considerate responses.
Oh, believe me I've had my fill of sump issues. With two in the basement
and a spring under the slab, I've been through 7 pumps in 23 years. BUT, I
don't worry about them as long as they're pumping water and shutting off now
