ECN Forum Forums General Topics of the Trade General Discussion Area Pool pump question.

If it was water I would expect the problem to clear if you ran the pump for a while ... at least until it rains again.
I know the drill I use to mix mortar and grout will trip the GFCI if I get it a little wet but if I take it to a non-GFCI and run it for a minute or two the problem goes away.
