Customer had a pressure reading of 120 psi in the home. The prv was no longer working, the whole house shutoff was leaking when turned off, the thermal expansion tank had failed, and the heater was over 20 years old. Re0laced the heater with a new shutoff, pan, and thermal expansion tank. Installed a new prv and shutoff. Set house pressure to 63 psi. Tested all work to ensure proper function and no leaks. None were found. Left quote for Flo by Moen and under sink RO system.
