Electrical question

[Delphinus]

One of my skimmer pumps is leaking voltage..

Is there anything to look for in terms of seeing if the pump can be salvaged?

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
