Repiping in Austin, TX

Repiping replaces a home's water supply lines, usually because old galvanized steel has corroded or polybutylene is at risk of failing. Most repipes today use PEX, take two to five days, and are done through small wall openings rather than gutting the house.

Repiping for Austin homes

Many homes built before the 1960s still have galvanized supply pipe, which rusts from the inside until pressure drops and the water turns brown. Some homes built between the late 1970s and mid-1990s have gray polybutylene pipe, which can fail at fittings without warning.

For the full guide, including what you can safely do before a plumber arrives, see repiping explained.

Local conditions

Repiping in Austin: what's different

Central Austin neighborhoods have older homes with galvanized and copper supply lines that may be ready for replacement.

Permits come from the City of Austin Development Services Department.

Many homes in Hyde Park, Travis Heights and Allandale were built before 1970 and may still have galvanized supply, which corrodes from the inside and causes low pressure and rusty water. Others have copper that is developing pinhole leaks after decades of hard water. A repipe usually runs new PEX through the attic and walls with small openings that are patched afterward. West of MoPac, shallow limestone makes reaching buried service lines slower, which matters if the main line from the street also needs replacing.

Repiping questions in Austin

How long does repiping take in Austin?

Typically two to five days for a whole house.

Is PEX or copper better for repiping?

Both meet code in most U.S. jurisdictions. PEX costs less, needs fewer joints, and tolerates freezing better than copper. Copper lasts a long time and handles UV and high heat better. Most whole-house repipes now use PEX.

Can I live in the house during a repipe?

Usually yes. Water is shut off during the day while lines are switched over, and most plumbers restore water each evening.

How long does a whole-house repipe take?

Most single-family repipes take two to five days, depending on the number of bathrooms, the number of stories and access from a basement or crawl space.
