Have you checked for stray voltage lately?

[Camlor]

A few months ago the no name feed pump for our reactors wasn't preforming very well so I took it out of service & ran it in a pail of vinegar hoping to clean it. It definitely put enough voltage into the pail of vinegar to get my attention, we now check for stray voltage every water change. Great Safety topic, we are now looking for a rid-volt grounding prob, thanks for bringing it up!
