Polybutylene Pipe Replacement
Depending on when your home's water system was last upgraded, you may have heard of polybutylene pipes. What you may not have heard is that this material was the subject of a class action lawsuit, and may rapidly degrade under normal use. If you have poly pipes in your home, John C. Flood, is uniquely positioned to help you upgrade to a more durable material before you suffer loss and damage to your home due to broken pipes. We served as an expert lawsuit in the class action lawsuit.
