Try turning off the power to the outlets and cleaning the plugs and
receptacle. Sometimes moisture can build up in dirt (usually spider
webs) and cause a slight leak of power to ground tripping the GFI. If
this does not work you may have a problem with one of the pumps, the
outlet or the GFI circuit breaker itself. Good luck Hank

Hi;

I have both of my pumps plugged into a GFI outlet. I know that I
should
have run 2 separate lines so that if one trips, the other will still
be
pumping, but I learned this too late. In the last month the GFI has
been
tripped twice. I go to the GFI switch in my garage that controls
these,
flip the switch, and the pumps come back on. What could be the
problem?
Fortunately, I have been home both times that this has happened.

Thanks-----
