The cold water inlet valve on the water heater was found to be corroded and no longer reliable. We proposed replacing the valve to restore safe, dependable operation and reduce the risk of leaks or potential water damage. Power was shut off to the water heater and the cold water supply to the building was turned off. The system was fully drained to allow for replacement of the valve. The corroded valve was cut out and removed, with the pipe cleaned and deburred prior to installation. A new quarter-turn shutoff valve was installed using a repair coupling. Water service was restored, the system was pressurized, and all work was tested with no leaks observed at this time.
