Voltage present in BRAND NEW fiberglass pool

Good morning Pool Peeps, hope your both well.

We are new pool owners with what we consider a serious problem. The pool installation was completed 2/23 so needless to say this is our first season with a pool. Upon initial uses we noticed a rather unpleasant feeling when touching the wet concrete from in the pool. Checked voltage and sure enough .900 VAC on the house side and 1.6VAC on the back side facing the woods. I informed the pool company about the issue but I also wanted to get the city involved due to a wire relocation that took place prior to the install. It was weird since the voltage increase was much closer to the tap location behind the pool, I hoped one of the taps was bad and voltage was leaching. I went ahead and killed the disconnect at the main and voltage was still present.

First round of city electrical. Pulled the meter and checked for a neutral issue, all good, no problem found there. At the transformer killed the 2 hot legs and voltage still present, killed the neutral and bingo, voltage goes away. They went ahead and changed the transformer, added additional ground rods at the transformer and still voltage present. Found some stray voltage back feeding from some cable providers in my neighbors houses but after isolating those issues voltage still present. They even checked several transformers in my community to verify no issues and they then found no issues. These guys even tested running new wires direct from the transformer to the house to test verify the splices weren’t compromised and the voltage was still present. The city head guy made a comment about the water not being bonded.

Second round pool company electrician. Guy told me the water is bonded along with the pump and the heater, however. He mentioned something I was also quite worried about, the concrete not being bonded. These guys didn’t use any rebar nor bonding grid, just a wire, we have 8ft of concrete on 3 sides with 20ft patio running to the house. The steel hand rail that doesn’t extend into the water, shows zero voltage.

The pool is fiberglass, salt water and heater.

Super concerned about needing to rip up and redo the concrete and wanted to get some input from a fresh perspective. I did watch your episode about a relatively identical scenario but I wanted to add some additional detail.

Thanks you in advance.

From what you describe it would be worth pulling up the concrete to ensure you have proper bonding and grounding. You don’t want to take any chances with voltage and electricity. It sounds like it’s the next necessary step.
