Water Heater Relief Device

I had the same problem with my Suburban WH and no procedure worked to fix it. There is nothing wrong with your valve most likely, it is a design issue with the water heater IMO. Suburban knows it’s a problem, says so in their manual, and has no plans to correct this feature. I struggled with this issue for four years and finally took Suburbans work around their problem solution.The only solution is to install a small pressure tank inline with the water heater. The pressure created by the heating of the water is absorbed by the tank and not blown out the relief valve.

I never had this pressure relief issue with an Atwood in five other motorhomes.

Thanks to all. I will try to re establish air pocket.

OUR suburban was doing the drip from the relief valve , did a complte flush ,no help, changed the thermostat , fifteen minute job , no more issues

"1- open and close the valve a few times, sometimes a small piece of debris will be stuck there allowing for a leak."

We think too much alike!

2- more likely you will have to replace the valve, which is quick, easy and painless.

That’s the first thing I did, open and close. Mine had just got bad would not seal . Yes it’s easy and inexpensive to replace . I didn’t mess with mine much , just replaced it .

Once tripped, they will often leak a bit. My trailer is an outdoor dog, so it’s not a big deal. If you are anal, replace it — and in due time, it too will dribble.
