Hello,
I know similar threads are posted often, but I'm trying to understand what I should do with this.
I have a 2018 home in TX built using cold expansion PEX. Recently, I discovered a small leak in an inside wall between the garage and the house, just behind the water heater. After removing the heater and section of the wall, I found the PEX pipe was squirting a tiny stream of water. Attached are the picture. I replaced the section myself with PEX and clamps, and there is no leak for now, as I did not want to try cold expansion for possibly already brittle pipe. The rest of the pipe looked good (nice red color) as far as I could see in the wall - but the section I cut out had weird color and was not flexible. The leak was above the joint and the size of a pinhole so I had no real damage. The heater temperature is set to 115F, and the pressure relief valve seems to work correctly. I also have an expansion tank installed on the cold line.
I sent the piece to Uponor for investigation but I'm not even sure if this is their pipe or what should I do next - prepare for tearing down all walls (and kitchen island floor - where the pipes go under the polished concrete)? Or wait until I notice another leak. Any ideas?
Thanks,
Peter
