Review: works well - Good fit works well
Review: Perfect replacement - I needed a new pressure relief valve to replace the one on my Rheem water heater that the plumber broke during "routine maintenance". After doing a lot of searches, and finding that the original part number had been replace twice (the hot water heater is 21 years old and still going strong) I found out that the part is now made by Protech. This one was an exact match to my old one, and installation was a snap. It even came prewrapped in Teflon tape, which was a nice surprise. Some things to note if you are replacing 1 yourself: - Make sure you turn off the water and unplug the hot water tank to let it cool. If you have gas, shut that off also. - Pump the old release valve to slowly let pressure off before opening it full. It will reduce getting an air burst and potential hot water blast. - Opening the hot water taps in the house also helps after you shut it down. I was flushing mine at the same time, so it helped greatly.

### ⭐⭐⭐⭐⭐ Functions perfectly with easy diy installation.
*by A***N on July 12, 2021*

I sold my home and the buyers, rightfully, wanted a home inspection. The inspector decided to pull the lever on the pressure relief valve that was working flawlessly, even though the drip pan below the pressure relief pipe was totally dry. It immediately started leaking, although slowly. I ordered the new pressure relief valve and when it arrived, I turned the temperature dial on the water heater to vacation, closed the cold water inlet valve and drained about 6 gallons from the water heater. After removing the drip pipe and slowly turning the old PRV until there was no steam or liquid water leaking, the old PRV was removed. The new PRV was immediately installed and the drip pipe replaced. After turning the water back on and setting the dial to a warm temperature, the water heater fired up and showed no signs of leaks. I was sure the inspector caused the problem when just before closing, the buyer's agent asked to go into the basement to check on the water heater. If you are inexperienced with plumbing, I would advise shutting the water heater down entirely and waiting for the water to cool considerably.
