Arrived to the home to fix the existing flu for the power vent water heater. A special fitting is required to connect the pvc piping correctly. I have arrived back on site to repair the flu piping properly. Cut out existing pvc piping. Supplied and installed new solid core pvc pipe, fittings, and special exhaust adapter. Secured all my connections and turned the power vent back on to check for leaks. There are no leaks at this time.
