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?
