When to Repipe a House

Recurring pinholes, rust-colored water, and pressure loss all point to the same conclusion: the supply piping is done.

Common causes

• Galvanized steel supply nearing end of life
• Copper thinning from aggressive water chemistry
• Recurring pinhole leaks in the same run
• Widespread pressure loss

Step-by-step

1. 01Cut a section of the worst run and inspect the inside wall
2. 02Ask for a whole-house pressure and volume test
3. 03Get a written repipe scope — copper, PEX, or hybrid
4. 04Plan finish repair for open-wall access
