Condensation pipe (?) dripping

Hi, I need some help (again). We bought our retirement home, but not quite ready to retire, so our grown kids are living there. It is in North Georgia, and we are in Texas. They sent us a picture of a pipe out the back that has been dripping a lot of water. Here in TX our A/C condensation goes into a pipe, and down a sink drain, if it is leaking outside, it is because the other one is stopped up. But my daughter said she traced this pipe into the basement and into the hot water heater (???). Of course we don't have basements here on the Gulf Coast either. I'm guessing this is A/C condensation, since it is dripping so much now, and I know they are running the A/C a lot now. We didn't notice it when we were there in April. So, just wondering if they do the condensation pipes different over there. I am going to try to post a pic they sent. TIA for all your help.

Looks like copper pipe... May be coming from the relief valve of the HWH. If its tripping there is a reason. Too much pressure or to high of temperature.

This is a safety issue and I suggest you get it looked at ASAP.

Verify where its coming from and call in a pro.

I would shut down the gas or electric to the heater and shut the HWH water valve off for safety purposes.

If it goes to the water heater it is a safety valve or relief valve discharge. Some houses have a pressure only discharge valve set at slightly higher than the domestic water supply pressure and this valve will discharge if there is not an expansion tank on the water heater. Over time this valve will erode to the point where it will discharge a small stream continuously.

If the discharge is hot water then it is the safety valve that is leaking. This could be caused by several different reasons but in either case it really needs to be repaired. Pictures of where this pipe connects to the water heater would help in diagnosing the problem.

So you think we should call a plumber, not an A/C guy?

Yes...a plumber would be the person to call if it truly connects to the WH.

It is hot water coming out of the pipe. Can they shut off the water going to the hot water heater to keep it from continuing to leak till a plumber gets there?

Yes they can shut off the water, but be sure to turn off the gas or electric also.
