How to Know a Repipe Makes Sense
A repipe usually pencils out once a home has had two or more slab or wall leaks in a short span, still has original galvanized steel supply lines, or was built during the years polybutylene piping was common. Galvanized pipe corrodes from the inside as McAllen's hard water deposits calcium and mineral scale along the interior wall, which is why older homes lose pressure gradually even with no visible leak. By the time a homeowner notices low flow at the shower head, the pipe interior may already be down to a fraction of its original diameter.
Repeat pinhole leaks are the other clear signal. A single pinhole is a spot repair. Three or four over a couple of years, especially in different rooms, usually means the whole run of pipe is reaching the end of its service life at the same time, and a targeted fix just moves the next leak a few months down the line.
