D.C. Voltage.

[Ltmoeller]

I periodically check my pool for stray voltage just as a precaution.I accidentally had my meter on D.C. And noticed 25v DC with one probe in the water on the other on the painted deck.No AC voltage.Maybe it's always been there.
Thanks Tom

That would be very unusual. Did you reverse the leads?

 

[Ltmoeller]

No

 

[JohnT]

I'd give that a shot just out of curiosity if nothing else

It’s dark I’ll do it in the morning.I have one of those shock alerts and it show no ac voltage.I’m going to check it tomorrow with a analog meter.

You should verify that the meter is working properly.

Are you sure that you mean 25 volts and not 0.25 volts?

Try testing a few batteries to see if the voltage reading matches the voltage of the battery.

Check to see if the voltage is zero with the two leads touching.

It looks like this is a continuation of earlier issues?

D.C. Voltage

Not sure if I have this in the correct section.I was having bonding issues last year so periodically I test the water for any voltage,all has been well.Today I tested it and by mistake I had my meter on D.C. And recorded .25 volts.Whats up with that?Salt system pool,using digital meter.

What's causing this voltage

I have a inground vinyl pool with concrete deck.I bought the house about a year ago pool was installed 10 years ago.Alabama is a non disclosure real estate state.We were told by a neighbor there was a tingle.We just started using pool 3 weeks ago no one has felt a tingle except my 4 year old...

Another bonding issue

I. recently purchased a home in Alabama with a in ground vinyl pool.It has a 3 foot wide concrete deck all around pool.I was not told by the seller their was a tingle in the pool.I can turn off main breaker to all of the system,put a volt meter probe in the water,the other probe on concrete deck...

25 volts dc seems very unlikely. If you can confirm that the voltage really exists, I would suggest a few tests.

1) Get a 24 volt LED light bulb and put it in series with the wire from the pool to the deck or ground to see if it lights up. Maybe put a piece of metal on the wire in the pool and in the ground to provide better contact.

2) Same thing but put a dc amp meter in series to see if current actually flows.

Based on your previous posts, it looks like you have had this issue from the beginning. Did you ever have a master electrician come out to evaluate and advise?

If you're really getting such high voltage, you should not allow anyone to swim until you can get an expert to verify that it's safe to use the pool.

I tested the pool this morning with a different volt meter and a analog tester and there is no voltage.Must have been a faulty meter.I had the pool completely retired after I bought the house by a journeyman Electriction and never an issue since.I just check it sometimes I guess for safety reasons.I have a safety alert you but in water used for around docks in lakes and pools and all checks out fine.

Glad for you. It seemed too odd to be real, but it seems like 90% of life is odd stuff.
