State select gas water heater with a expansion tank on the top

possibly leak from a rusting tray?

Any advise about repairing this?

Approach the gas utility?

lot's of good advice in this thread.
You might want to consider direct vent wh
also
for all gas water heater owners, once in a while run a lit match around the diverter above the wh while it's running. If it blows out you have carbon monoxide spillage. It's odorless.
Call your plumber if this occurs.
If this occurred say in ny the wh would be tagged off and isolated from the gas piping system.

It does look like an improper installation in the picture because the expansion valve doesn't drain into the drain pan. Water will leach up into drywall over a period of time

We had the exact same thing last year. Since the dry wall is already wet and has to be replaced anyhow, I pulled out the wet drywall to expose the area. It wasn't my hot water tank, but one of the drainage pipes(pvc), from the HVAC that goes through the wall to the exterior, had disconnected at a joint and the water was running down the pipe through the pipe insulation to the interior of the wall. Easy and inexpensive fix, but a pain. So I guess my first thought is tear out the wet drywall and look for the source.

Thanks to an earlier post, I now have captured the water coming out from the pressure release pipe and the previously wet area is now dry,

Thank you

We have arranged for a new water heater and expansion tank to be installed
The installer/plumper will allow me time to repair the damage between the old out and the new WH install.

The State Select WH has a 2006 build date….so it is time for new

Many thanks to all responders

Stay safe

Can’t tell directly from the picture but it looks like the water temperature on your gas water heater is too high. Temperature should not be set above 135 degrees because of scalding hazard. If the temperature setting is causing the water to boil, this may be the cause of over pressure, thus the pressure relief valve could be going off occasionally. Water shooting down the pressure relief pipe could be splashing back up from the pan and making the wood and drywall wet. Also suggest you pour some water in the pan to see if it has a hole in it, which would then have to be replaced. Lots of work to replace pan ! I’ll have my friend who use to repair these gas devices look at this picture and see if the temperature setting is too high. Get make to you!

Recommend gas rebate for new gas water”heater. Gas to gas $350 to $ 500. Maybe more for Electric to Gas. Check Seco Rebate for Electric water heater and tankless rebates.

change everything, you got your money's worth.

Water Expansion tank …BUT it looks like yours is mounted on the hot side rather than the cold supply side! ANYBODY ELSE SEE THIS

[RICH1]

Great … I left a comment about expansion tank

[RICH1]

It should ,,,,,

Maybe. The recommendation is the cold side, but it will work either way. I have seen it done both ways. I think they recommend the cold side because the expansion tank will be more durable with cold water in it.

Talked with my friend who looked at the temperature setting on the water heater. He said it looks like the temperature setting is on the very high side. If you look at the temperature control knob you can see where the arrow is on the knob. That arrow is where it should be. He suggests turning the setting back to that arrow. If that doesn’t do the trick it may be a weak pressure relief valve on the top of your water heater which means it would have to be replaced also, and if neither of the two option he mentioned don’t work then the temperature control mechanism could be bad. Hope this helps.
