Whole-Home Repiping Cost in Austin, TX: Is Your Polybutylene Pipe a Problem?

Whole-Home Repiping Cost in Austin, TX

If your Austin home was built between 1978 and 1995, there's a good chance it has polybutylene (PB) pipe — a grey plastic supply line material that was widely used and is now known to fail without warning.

Polybutylene Pipe: The Problem

Polybutylene (brand names include Quest and Vanguard) reacts with chlorine in municipal water, causing the inner pipe surface to flake, crack, and eventually fail. Austin's city water uses chlorine and chloramine for disinfection — accelerating the degradation.

Signs of polybutylene pipe in your home:

Grey plastic pipes visible under sinks, at the water heater, or where supply meets wall

"PB" or "P.B." stamped on the pipe

Built between 1978–1995

PEX vs copper: PEX (cross-linked polyethylene) is now the standard choice for repiping. It's flexible, resistant to freezing, and doesn't corrode. Copper is more durable long-term but significantly more expensive and prone to Austin's hard water buildup.

Shut off main water supply

Access walls and ceilings to reach all supply lines

Remove old pipes and run new PEX throughout

Connect at fixtures, water heater, and main shutoff
