Was your house built between 1978 and the mid to late 90’s? If so you have a one in four chance that polybutylene piping was used in the supply plumbing. Polybutylene is no longer allowed since its failure rate was so high; however, it is still in many houses waiting to fail! Here’s what one expert says, “With regard to elastomers, the study showed that with few exceptions, solutions of chloramines … produced greater material swelling, deeper and more dense surface cracking, a more rapid loss of elasticity, and greater loss of tensile strength than equivalent concentrations of free chlorine." In other words, the longer you pump chlorinated water through polybutylene piping the more likely your pipes will fail and possibly flood your house. And the real problem is you won’t know where the pipe will leak first. Call us for more information about polybutylene piping.
