Hello everyone,
I recently installed a new electric water heater. The pressure relief valve keeps popping off non stop within seconds of water starting to fill the tank. Please note there is no expansion tank installed and there is no pressure reducing valve installed on the plumbing system. Also no back flow device.
I checked the pressure coming into the house and it's averaging around 130 to 140 PSI. My understanding is this is high and a pressure reducing valve would fix this. Would this also be the reason the pressure relief valve on the water heater is popping or could it have shipped with a bad pressure relief valve?
Should I go with an expansion tank first or the pressure reducing valve?
