HELP!!! Plumbing Question!!!

[txrdkng]

I have hot water flowing (not dripping) out of a drain line on the side of my house. There are two drain lines side by side (obviously one for each heater) but only one is flowing. I am no plumber and don't know what's causing this. I shut off the heaters and turned the water off to them and it stopped but we will start gettin pretty stinky soon . Who's the expert here?

Thanks

No expert but sounds like a pressure relief valve or tank rusted out and overflow pan draining. Is there water in your pan under the heater? If not, I'd bet it's the pressure relief valve

Pan is dry as a bone. Pressure relief valve makes sense.

T&P Valve(Temperature and Pressure) You can buy a new one at Home Depot, Lowes or Ace. All you have to do is drain down the tank below the line of the T&P, unscrew the old one, screw in the new one and re-connect the drain line.

Sounds like your T&P line. I assume you mean Water heaters? If so isolate witch one it is. There is a valve either on top, or on the side of the water heater that is designed to release pressure if to much builds up. you can replace it, it just screws in. You will obviously have to cut the drain line, and hook it back up to the new one. Good luck

And obviously I type slow as ....

Thanks, and that all makes sense. Found what you are talking about....and yep, no easy "unscrew the line from the valve". All cemented together. Darn.

Could this be an AC overflow condenate pipe? Is the water hot ?

It should have some stop leak dope on the threads but not cement. They can be a real bugger to get out but it should break loose. Only other option is a new water heater.

If the one with the problem is over 10 years old I would replace it anyway. Spend $50 more on one with a really good energy rating and save some dough on your energy bill from now on.

How old is the water heater?

Is anyone on here, or do you know of a good, reliable, honest plumber in the Tomball area? Quickly?

A relative's did the same thing. Problem was that they have a pier and beam foundation and they had no idea that the water heater valve had been draining for a long time and I didn't either. Thankfully a gas company employee was over to adjust the gas pressure at the meter and went to relight the water heater and heard the water draining. The water drained under the house. I went to Home Depot and bought another and installed it in a short while. Had to unsweat the drain pipes and reattach.
It stayed very damp for a long time under that house.

The water bill was shockingly high that month.

If its a metal valve/pipe connection you can try to heat the threads with a flame to loosen the dope up for removal. If anything is plastic....dremel.
