View Full Version : Eheim return pump cord shocks

I noticed tonight messing around in the sump that whenever I touched the cord for my return pump it would shock me. It wasn't a really really bad shock but when I nipped it with my fingernail it gave me a little zap and my reflex jerked my hand away real quick. Why is it shocking me?

not grounded?

no. How do you do that? Is that the problem?

Grounding won't help. You need to disconnect it and check for exposed wires.

IMHO, that's not good. None of my Eheim pumps have ever done that.

"It wasn't a really really bad shock" just means you got lucky! Don't mess around with it. Turn the power off and unplug it. If you don't know how to safely test it for a current leak and safely fix it, you should toss it. Also, if the spot where you touched the cord was slightly wet in any way, then you should also be concerned that it might be something else in your sump (like a heater) that has a current leak into the sump, so you should check those as well. And don't check them by dipping your finger in the sump!!
