Review: Direct replacement for my RV/Travel trailer Water heater pressure relief valve - 100% percent match and direct replacement. My existing one was starting to drip after ten years of service. I did test it every year as directed. This new one was a direct specification match and resolved my issue. tested ad looks to be good for a while. Quality looks identical to the OEM valve.
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.
