If your home was built or renovated between the late 1970s and mid-1990s, check for Poly B plumbing by:
- Looking for gray or blue flexible pipes, often marked with “PB” or “Polybutylene.”
- Inspecting areas like the water heater, furnace room, or under sinks where plumbing is visible.
- Consulting a licensed plumber from The Super Plumber for a thorough inspection.
