Removed drywall in the upstairs hallway bathroom and kitchen ceiling so we could find the source of the water leak in the kitchen ceiling. All water piping behind the shower valve in the upstairs hallway bathroom is nice and dry at this time with no issues. The leak was coming from a 3/4x3/4x1/2 quest tee located in the kitchen ceiling. Installed new 3/4x3/4x1/2 pex tee with all new quest by pex adapters, existing water line is now working as it should with no issues or leaks. Vern’s plumbing will NOT warranty this work due the condition is the existing piping, the homeowners are aware of this. Highly recommend we return to pull/reset the upstairs hallway bathroom toilet and install a new 1222 Moen shower cartridge in the upstairs hallway bathroom. Also spoke with them about replacing all of the water piping in the home. They don’t want to do that at this time because they’re in the process of selling the home. Homeowners had no other plumbing questions or concerns at this time.
