Poly-B<\/h2>\n

Information on Polybutylene Piping<\/h3>\n

Do you know if your home uses Poly B tubing? Polybutylene pipe (Poly B) is a flexible grey pipe used in residential plumbing and hot water heating systems. Poly B was manufactured from 1978 until 1998 when it was discontinued. Available for quite some time, Ploy B was used more heavily in BC and Canada when residential construction was strong during the 1980\u2019s and the early-to-mid 90\u2019s. Unconfirmed estimates cite that there are in excess of 200,000 homes in BC with Poly-B water systems and affecting some 700,000 homes across Canada. If you suspect that your home uses Poly B tubing you should have it checked out as it could lead to major water damages later.<\/p>\n

Poly-B supply piping was the first generation plastic piping system designed as a substitute for copper supply piping. Escalating copper prices made Poly B pricing attractive, and because it was less labor intensive to install than copper. Here in Canada, Poly B was tested and certified by the Canadian Standards Association (CSA) as an acceptable product for potable water systems. As of 2005, the NRC-CNRC National Plumbing Code does not list Poly B as an acceptable plumbing piping material. NRC-CNRC plumbing codes are not retroactive, so previously acceptable products that are not currently listed still remain acceptable as long as the product does not pose a health\/safety hazard.<\/p>\n

There are two primary components to the Poly B plumbing system, the grey piping and the connection fittings used to join the pipes.<\/p>\n

Poly-B plumbing problems<\/h2>\n

All plumbing supply systems experience failure, but some fail prematurely and without warning. Contributing factors that cause premature Poly B failures center around connection failures, pipe failures, water quality, age, and faulty installation.<\/p>\n

The factors that cause Poly B failures include:<\/p>\n
