Why 90% of Plumbing In New Homes Is Already Failing (The PEX-B Trap)

There's a 90% chance your home's plumbing is made from the cheapest version of a material that begins chemically degrading the day hot chlorinated water starts flowing through it. That water stain on your six-year-old house isn't a bad fitting — it's the first visible symptom of a predictable failure pattern your builder knew about and installed anyway because it saved them $1,200 per house. A single letter stamped on the pipe coming off your water heater will tell you if you're sitting on a $10,000 repipe, and the clock is already running. I'm going to show you exactly what to look for, why the chemistry fails, and the specific contract language that prevents this from ever happening in the first place.
