Stray Current??

[adesalvo]

I agree about the possibity of the bond wire, but the wire also attaches at the pump (it is in a crock under the deck) and the voltage is essentially 0 at the bond wire that I can test at the pump.

I tested it today with my voltmeter, I lead in the water and on lead on the concrete deck with a puddle of water....between 5 to 7 volts...

I will try to call the electric company and see what they have to say...

My guess is that the rebar in the deck either wasn't connected to the bond wire or that corrosion of the rebar has caused the connection to fail. I don't know of a good solution.

First, find the source of the current and fix that. Defective well pumps are a common cause, but most any kind of defective or miswired electrical equipment, even a neighbor's equipment, can cause it. Also, poor grounding practices by your utility can cause stray voltage as well. Once you get that figured out, then you need to figure out why your bonding system didn't stop it from affecting the pool.

If you are in an area that has dairy farms, your power company will probably be familiar with the problem. Otherwise, you may not get any help from them even if it is their fault.
