I'm sort of suspecting "no" but I thought I'd give the pump a once-over tomorrow nonetheless. Likely though I'm buying a replacement ...

Question #2 ... why wouldn't it have tripped the GFCI if I have a grounding probe? Is there a minimum threshold for creating a ground fault?

I realize that the skimmer being in the sump that the ground probe should also have been in the sump, but I could feel the trickle of electricity in the display so I thought it would have gone to ground and thus tripped the GFCI? The GFCI trips pretty easily in other circumstances.

Just wonderin' .. thanks

Not trying to be smart here, but is the skimmer plugged into a GFI (I've got a mix of GFI and non-GFi receptacles around my tank) or could the GFI be faulty?

Also for GFI's aren't they to trip within a 1/2 cycle, so that if you did grab that hair dryer that fell into that un-grounded sink, as soon as you reached in and provided a ground path it would immediately trip?
