When a Dallas Home Needs to Be Repiped

Most homeowners do not know their pipes are in serious decline until a problem forces the conversation. By that point, there is usually a pattern of issues that has been building for years. Here is what drives most repiping decisions in Dallas.

Galvanized steel pipe was the standard in Dallas homes built before the 1970s. It was coated in zinc to slow corrosion, but that coating breaks down over decades of use. Once it does, the pipe corrodes from the inside out. The rust narrows the pipe bore, reduces flow, and eventually flakes off into the water supply. Rust-colored water, low pressure throughout the home, and repeated leaks at fittings are the clearest signs galvanized pipe has run its course. In DFW, mineral buildup from hard water accelerates that timeline.
Polybutylene was used widely in Dallas homes built between the late 1970s and mid-1990s. It was inexpensive and easy to install, but it degrades when exposed to chlorine and other oxidants in municipal water supplies. The degradation happens from the inside and is not visible until the pipe begins to crack and fail. Polybutylene failures are unpredictable and the material cannot be repaired reliably. The only correct answer when a home still has poly pipe is full replacement.
Copper is a quality pipe material, but it is not immune to failure in DFW conditions. Hard water with high mineral content, combined with slightly acidic water chemistry at certain points in the Dallas distribution system, creates conditions that produce pinhole leaks over time. A single pinhole is a repair. A pattern of pinholes appearing in multiple locations over a short period means the pipe itself is the problem and spot repairs are just buying time.
If a home has needed multiple pipe repairs in a short window of time, the repair-versus-repipe math usually starts favoring replacement. Every repair costs money and causes disruption. At some point the cumulative repair cost approaches what a repipe would have run, and the new system would have been in place the whole time. We give you both numbers honestly so you can make the decision with full information.
