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.

From Crown Farm to Science City, we’ll help you get the water running into and out of your home as smoothly as possible. We understand that disruptions to your plumbing are frustrating and difficult, and we’ll help you through them as quickly as we can. Contact us today to schedule a repair, whether it’s as small as a toilet that doesn’t quite flush, or as big as a brand new water heater.
