Used this to replace faulty check valve in a friend's motorhome. Works just like it should.

I needed a check valve for my travel trailer's water heater. It is needed for winterization. It worked as it should. The brass body is what drew me to this check valve over other options.

Used this to replace the flimsy plastic check valve that cracked just behind the threads going into the hot water outflow. I have the 12 gallon Suburban DSI WH and it fit perfectly once I cleaned the plastic out of the threads (very tedious). Do yourself a favor and examine the back of your WH to see if it has the plastic check valve and replace it with brass if it does. A friend also had this happen on his Solitude (although it’s not unique to that model or Grand Design products). It’s not a matter of if it will crack, but when!

Our RV lost hot water pressure, it would give a very short blast, than nothing. I searched on the issue to find this pressure release valve was the problem. They were right, the little cap that held the spring was gone. Apparently the pieces fall into the tank and will flush out at some time, nevertheless RV has constant hot water pressure. Good quality, sealed right up and works great.
