Hi. A little background...after converting my pool to SWG in 2013, my pool developed a 1 - 1.5 volt potential difference between the Aluminum coping, ladders, and the pool itself. To troubleshoot, I mechanically disconnected all power from the pump, SWG, and light...the voltage remained. The local power company came out to determine if there was an underground power leak. After disconnecting my transformer and two of the neighbors transformers, they could find nothing. They cleaned, and replaced several ground connections and bonding connections, but they found nothing.
Three years later, the 1 - 1.5 volt shock remains. I took care of the ladder issues by replacing my stainless with polymer ladders. The only remaining point of shock is the aluminum coping. My plan is to remove sufficient concrete from the coping, to attach a copper grounding wire to the coping with a stainless bolt, cover the connection with silicone, patch the concrete, and connect this wire to the bonding wire from the pool. As a last step, I'll mechanically join each section of coping with stainless screws.
Thoughts? I don't see that I have any other options short of tearing out all of the decking, and having the bonding redone.
