What Repiping Is and When It Makes Sense

Repiping is the process of replacing all or part of a home’s supply lines with new pipe material. It is not a repair, it is a system reset. The existing pipe is removed and new material, typically PEX or copper, is run in its place from the main shutoff to each fixture.

Plano has a concentrated pocket of homes that are prime repiping candidates. The U.S. Geological Survey documents how hard water accelerates internal pipe corrosion, and Plano’s water supply is among the harder markets in North Texas. Galvanized steel lines from the 1970s and 1980s corrode from the inside out, reducing flow, discoloring water, and eventually failing. Homes built through the mid-1990s in subdivisions like Willow Bend, Spring Creek, and Los Rios may still have polybutylene pipe, which is no longer code-compliant for new installations and is prone to sudden cracking without warning.

The decision point is usually one of these: the pipe material itself is the problem, spot repairs have happened more than twice in the same system, or a full inspection reveals widespread corrosion that makes further patching financially irrational.
