The issue: When entering or exiting the pool through the shallow end, and you grab the railing you are feeling like you are being shocked. This is not happening anywhere else in the pool. The deep-end ladder isn't demonstrating this issue.
Info: The pool was built in 2003 and is bonded with a #8 copper wire from the pool motor, over to the four corners of the pool, hand railing anchors in the shallow end, deep end ladder anchors, pool light, and the concrete rebar; it all passed inspection. This issue has never happened until this summer, June 2021.
Testing and isolating: Voltage from the railing to the concrete is about 1.5V and railing to the water is around 1.9V. When we disconnect the ground wire to the house, the voltage drops to .0023V at the railing in the shallow end, and the shock goes away. This is the closest point to the pool motor from where the bonding begins.
We have solar panels on the house. We had them come out to verify that there isn't a voltage leak or grounding issue on their equipment. With all of their equipment unplugged, power off, main breaker to the house turned off, we still had the voltage in the shallow end. Over by the pool motor, we were seeing around 3V on the ground. Absolutely NOTHING was turned on at this moment. All of the solar equipment checked out. The next course of action, check with the power company to see if there's a load issue. They came out, performed a load test, and everything checked out. The house grounding rod is secure and reads 0V. We've taken out breakers, disconnected all of the wires for the pool motor, timer, outdoor outlets, checked the GFCI's. Nothing, absolutely freaking nothing is leading us to the source.
We've never had this problem, but it's only isolated at the railing in the shallow end. I'm planning on removing the railing, cleaning up the bottom section for better contact, then taking a wire brush and running it inside the anchors to see if that helps.
All of the bonding is encased in concrete. However, is there a possibility that the anchor lost its bond? Any insight would be helpful. Thank you!
