This is one I couldn't find any other posts about:
We had an inground Vinyl liner pool put in last July. Well after the cement was poured we had guests over and the wife got shocked on the cement while in the pool. After experimenting ourselves with one foot in the water and one out for example we could feel the "shock" or electrical current on the metal handrails and on the cement on one side of the pool. We experimented with the pump on and off and could always feel "something." we usually could only feel it on a scraped part of our skin or open wound. Went and bought a more sensative voltage meter and were able to measure about 1 volt of electicity between the cement and the water. Our contractor who put the pool in came and retrenched all the wire from our well pump to the meter......our well is on a meter by itself and the pool electrical equipment is wired to that. I guess I should have held the contractors feet to the flames a little more than I did because even after the retrenching of newer wiring from our well pump to the meter we could still feel current.
I personally haven't felt it since opening up the pool this year but my children say they do. The tell tale sign is when they dip one foot in the water and keep one on the cement they say it feels like stinging.
I know this is an odd problem to post, but I thought I'd throw it out there. It is a problem that never seems to have gotten worse so I was likely to ignore it. If anyone has experienced this or has thoughts on it, please enlighten me.
