Homeowner had a previous leak due to defective Nibco Pex. Handyman found leak between the hallway bathtub and master shower. The 1/2” pex connected to the hot side of the bathtub was leaking. Handyman had already made access through sheet rock. Due to the wood blocking I was not able to access and replace all of the piping. I replaced what I was able to access. Pressurized the system and verified connections. No warranty on defective piping connections.
