Review on Watts LF100XL DP TT 150 4 Inch Temperature Pressure by Charley Martinez

I had hot water from my kettle in the camper van. Upon opening the access door, I found that the pressure relief valve was leaking heavily. I just turned off the hot water heart on this trip and when I got home I ordered a 3/4 LF100XL. They took the old one off with a simple crescent wrench, used plumbers, caulked the threads, installed a new one and lightly tightened it with a crescent wrench. Problem solved, hot water and no leaks! Great valve.
