Attention all Georgia homeowners: If your house was built between the late 70s and mid-90s, you could have unsecure blue polybutylene main water mains running under your yard from your home to the city or county water main. Polybutylene is a plastic resin and is used to manufacture water supply pipes. Due to its low production costs and ease of installation, polybutylene piping was the primary pipe system in many newly constructed homes and housing developments.
Polybutylene pipes react with the oxidants in public water supplies, such as chlorine, causing the interior of the piping to flake and become brittle. This results in many micro-fractures that jeopardize the integrity of the piping system. Pipes will eventually become weak and because the damage is internal, the piping can fail without warning and cause costly building and property damage.
