Where Can you find Polybutylene?

Look for Polybutylene inside your home by the water heater and on the walls running towards the sinks and toilets. The polybutylene underground mains are usually blue, but sometimes gray or black. If you find any Polybutylene, it was most likely used throughout the entire house.  Repiping would replace all the polybutylene from the main valve cut off, throughout the house right up to where it connects to your faucets. Replacing the faucets is not part of the repiping but can be quoted separately.
