Great info but has anyone found the same culprit or has it been a different solution for all? My pool is in Sandbridge in Virginia Beach. I have noticed a very mild tingle for a few years and no one else ever complained. Now fast forward to 2012 and the shocks are much worse to the point where the kids will not enter (probable a good thing)! The pool is about 15 years old, vinyl liner, saltwater, new pump. I use this house as a weekly vacation rental during the summer and need some help ASAP.

You need to call an electrician immediately. If you are renting the property out your liability is enormous.
