### ⭐⭐⭐⭐⭐ Exact Fit OEM R.V. Water Heater Relief Valve
*by R***1 on July 13, 2014*

I Installed this part for our Travel Trailers hot water heater that began to leak on our last trip. It is an exact factory part that installed very quickly and easily. Only had to remove the old leaker which was in tight but a large pair of Channel Lock pliers worked to get loose and I taped up the threads with some heavy duty Teflon tape to seal up the connection. Used a large crescent wrench to tighten up which worked well with the valves construction. I am sure it will do it's job and protect the water heater and not leak. Very good parts to choose from on Amazon and the prices and selection can't be beat. Thanks
