dual T&P valves a good idea?
doing a remodel where I have extensively re-worked the plumbing. Water heater is in a walk-out basement, was plumbed with the usual 150 psi relief valve out the side of the tank, piped down toward the floor. There was also a 125 psi relief valve on the hot pipe shortly after exiting the tank, plumbed up and outside through the nearby exterior wall.
Is this a good idea, should I go a little out of my way to incorporate this into my new piping scheme? Or should I just keep the 150 psi valve and call it good?
now have a PRV/expansion tank
wasn't sure if the 125 psi relief was common or not. The previous owner had a solar panel/pre-heat system with all the attending pumps/valves/solenoids for the hot water that was defunct and is now gone. I wasn't sure if the extra T& P had something to do with that or not.
