Big Mistake!! help

If a water line in a house received 240volts would the gas valve on a hot water tank be save to use

Probably but do NOT use it until it is tested for safe operation. The line could ONLY receive 120 volts, unless there was an EXTREME failure inside the house.

Every appliance in the house got fried. Any braided supply lines touching metal got fried and bursted. The ground wire melted and caught and started a fire. Transformers blew. There was 240 to the water lines. Someone messed up hooking up a transformer to the house

So I'm thinking the tank got 240 to. If the tank did the gas valve did

You have to understand WHAT 240v is. I do not know how it could have gotten into the plumbing system because the wiring is SELDOM connected DIRECTLY to the piping, except through the ground wire, and that, by definition, is attached to the GROUND/EARTH.

The ground wire was attached to the copper water line. The main ground and live wire was wired wrong.

still only 120 v. then if there was only ONE live wire attached, but still enough to cause damage.

It's my understanding that metalic water pipes should be bonded to ground, but not be THE grounding source. As HJ said, wiring one leg of the transformer to the ground should only have 120vac potential IF a proper ground was installed at the entrance (usually, ground rod(s)).

The transformer before the house was hooked up wrong. Sending 240 or more

Doesn't matter neighbors gas hot water tank fried to.

 

[Plumber69]

You guys don't get it there was a cross connection between live and ground before the house

Trying to figure out what exactly is being asked here. There was an electrical accident, and some stuff got burned up. Check. Presumably
that is now cleared? If not, then it is unsafe to touch anything in that house until it is. There's no indication that the gas valve on the water heater was damaged, and there's really no reason to think it was affected in any way. Gas lines are not necessarily connected to any system ground,
and water heater connections typically insulate the heater from the water pipes anyway. I would just try the valve and see how it works. Of
course, I would be aware of where the house gas meter shutoff valve was. Just in case.

240volts got transfered to the water lines. The gas hot water tank is all metal. Therefore the gas valve would of got 240 volts to. The neighbors gas hot water tank wouldn't fire up either. That house got fried to
