2017年9月26日 · Place one wrench on the TPR valve, to prevent the valve from moving (a pipe wrench works well). Place the other wrench on the drain tube. Use the first wrench to hold the TPR in place, when you use the other to unscrew the drain pipe. Cut the new pipe to length. Apply PTFE tape (or your preferred pipe dope) to the threads of the pipe.

2016年9月2日 · Good Afternoon, Been coming across several TPR discharge pipes that are very close, if not touching, the bottom of a water heater drip pan. What is the minimum distance from the bottom of the drip pan? Should’t there be some air gap? I understand the 6 inch rule for discharging to a waste receptacle but how close can the pipe be …

2024年4月26日 · To me #6 in that list is the fall safe needed to detect a problem with the TPR valve. In my area hard water will leave deposits on any valve or leaking pipe joint. The hidden deposits inside a leaking TPR valve could prevent it from working. I always make a point to tell clients water should NEVER drip out of the pipe, if it does call a plumber.
