Why repiping comes up in Bellevue

Mid-century homes still have galvanized lines that rust and lose pressure.

Bellevue's median home dates to 1984, so the typical house was plumbed with copper or CPVC supply, plastic drains, and in some homes gray polybutylene supply pipe. Repiping in these homes is usually about a specific material problem, such as polybutylene or repeated pinhole leaks in one copper run, rather than a whole-house rust problem.
