Customer had a leak on 3/4 cold line coming off the water heater in the garage. Pipe was located in the wall of master bathroom near the shower valve. Cut out and repaired section of pipe, and replaced the prv in the box outside because the pressure was high. Read pressure at 110 psi. Checked on another water source with another gauge because the pressure reading had been 60 the week before. Still had a high reading with a different gauge. Thermal expansion tank is still working properly. Noted an old shutoff leading to the exterior of the home. Found it was for a hose bib that was no longer installed. Capped the line as a courtesy. Checked all work to ensure proper function and no leaks. None were found.
