-The pool has a Salt water generator (220vac) which is connected in parallel with the Hayward pump (2hp), wired for 220vac, i.e., both are on the same ckt breaker and swithed on together. There is no timer.

-My understanding is that the only way the copper bonding loop ever connects electrically to the pool water is through the pool pump.
I extracted a few things that might be worth thinking about:

Wells can contribute to stray voltage issues if they have any wiring issues. Sometimes they are wired by people who aren't electricians.

Your pool is somewhat unique in that your water is truly insulated from everything by the polymer walls and lack of a ladder.

Is your SWCG connected to the bonding system? This is a system designed to electrically contact pool water, so it could be a source.

The water should never come into contact with the electrical system ground via the pump unless there is a seal failure in the pump.


When you pull the bond wire from the pump case, barring a leaking pump, you are only disconnecting the pool bonding from your electrical system ground. It would appear that in your case, your bond wire is actually energizing your paver decking. That's not too surprising since you are somewhat remote. Your utility's service is probably poorly wired allowing significant difference between the ground and neutral.

Based on what you've said, I have to assume you don't have a light in the pool either, as this would tend to bond the water as well. If you do have a light, I'd bet it isn't bonded.
