Need help diagnosing a problem if anyone here has experience with it. Rental house is getting 2volts to the shower knobs according to the tenet (dude). Did some preliminary research and found that it could be as simple as voltage coming from the tankless hot water heater or even just that the pipes are not grounded. Any advice on how to go about diagnosing?

Call an electrician to check this out.

That could be from what you said, but also a lack of solid house ground and a hot wire shorted to your house ground.

Chasing elevated grounds is not easy.

Is it shocking him? I'm just curious how he noticed 2 volts? I guess you can feel it?

One way to diagnose it would be to put the volt meter on it and then turn off the main breaker to the house. That should stop it. Then turn it back on, and work through the breakers until you find it. Go from there.

ETA: now that I think about it I can't believe someone that was capable of measuring 2 volts wouldn't have thought to turn the breakers off until the voltage stopped.

Most likely a ground problem, but at only 2V it's more probably a bad connection rather than a missing ground connection. If you have access to metal plumbing just look for ground straps and check for good clean contact. Also look for pipe sections where new pvc interrupts an old copper connection. If you find that, run a copper ground wire across the pvc gap. More likely in an old house.

Years ago had a house where tub plumbing gave me a 25V tingle. Inspection found a dangling ground strap in basement. When ceiling tiles installed ground wire was in the way.

Had this problem in my dad's house when I was a kid. It persisted for years until the AC condenser unit went out.

A rat had climbed in the breaker box for the AC and euthenized himself. His carcass shorted the ground and caused occasional shocking when using the tub or kitchen faucet.

Problem ceased after the rat carcass was removed.

Rental house


Call an electrician.

If it was my house I would maybe try to find it, but with it being a rental, you really don’t want something crazy to happen and you get sued.

I would troubleshoot by turning the main breaker off to the house…if the voltage disappears, the problem is somewhere in the house.

After that, flip the breakers one by one to see which circuit it is on.

How does he know its 2 volts? 2 volts to ground or between the knobs? If it is between the knobs its a meter problem. If it is to ground it may be an actual electrical problem but probably not. If it was a tradition tanked water heater it would the element going or gone bad.

Update: called electrician and it was a grounding issue with the bathroom outlet. Problem solved for $150.

Thanks all for the good advice.
