Failing PB plumbing systems are still wreaking havoc on homes.

A poly butylene plumbing system recently failed in a Boynton Beach, Fla., home causing the ceiling to cave in. Local news reports say the collapse was caused by a leaky pipe in the roof, which came crashing down on the floor inside the home. 
PB has a history of failure, and has given way to two class action lawsuits in recent years. Unfortunately, the recovery period for both lawsuits has ended and homeowners insurance must be tapped to fix the problem, or repairs are made out-of-pocket.
According toCBS 12 News, plumbing experts are urging people to have their plumbing inspected for PB plumbing systems in order to take the necessary steps to replace it.
