Is it a persistent issue? That must be frustrating after carefully calibrating everything.

Seeing the pipefitters install that PEX manifold after the flood must have been a moment. I've heard similar stories where the reduction in potential leak points with a home-run system is dramatic, like going from dozens of solder joints to just a few crimps. But ray's point about older homes nags at me, because retrofitting can be messy when walls are already closed up. How did the pipefitters handle integrating the PEX with existing fixtures, especially if the client's home had mixed materials? It seems like the ease of repair might depend on whether you're doing a full re-pipe or just patching a section.
