Review: Fits the RV water heater we needed it for - It works! Quite easy to install. It looks a bit different, but fits and performs as it should.
Review: Perfect replacement for my motorhome's water heater - The relief valve on my motorhome failed and would leak really bad when the water was fully heated. I was concerned that maybe it was getting too hot or too much pressure. But this was the first logical part to replace. Fixed my problem.
