Poly B Replacement in Langley, BC

Replacing Poly B in Langley Homes

Poly B is the grey plastic supply pipe stamped PB2110 that went into Canadian homes from 1978 until roughly 1995. It was designed for about 25 years of service, which means every system still in the ground in Langley is past it.

Walnut Grove is the Langley neighbourhood we get called to most for Poly B — it was built out squarely inside the window.

It fails from the inside out — chlorine in the municipal supply makes the pipe wall brittle, and the original grey acetal fittings are the weakest point in the whole system. Nothing about that is visible until water appears somewhere it should not.

We replace the lot in PEX-A, plan the routes first so we open as few walls as possible, and finish with the permit, the inspection record and photographs.

About Langley Homes

Why Langley Has So Much of It

Walnut Grove and much of Brookswood and Murrayville were built out through the late 1980s and 90s, which puts a great deal of Langley housing inside the Poly B window. Willoughby is newer and largely past it.

Langley runs colder than the coast in a cold snap, and acreage properties often have long, poorly insulated runs.

FAQs

Poly B Replacement in Langley — Questions

It is no longer made or installed and it came out of the plumbing codes, but there is no law requiring you to remove what is already in your Langley home. The pressure comes from insurers and from buyers, not from the City or Township of Langley, depending on your address.
It routinely comes up in the inspection report and gets negotiated against the price — often for more than the replacement would have cost. Replacing beforehand removes the bargaining chip and widens your buyer pool to people whose insurer will not write a Poly B home.
"It has not leaked yet" is not a measure of condition. Poly B degrades from the inside and the cracking that causes a failure is invisible from outside the pipe. Most people we work with are replacing because of an insurance renewal or a pending sale, not because of an existing leak.
Look at the supply lines where they enter your hot water tank, then under the sinks and in the crawlspace. Poly B is grey or blue-grey flexible plastic, stamped PB2110 every few feet. If it is grey and it bends by hand, that is almost certainly it. Here is the full identification guide.
It tracks build date rather than postcode, so the answer is wherever the housing went up between 1978 and 1995. In Langley that means Walnut Grove, Willoughby, Brookswood are all worth checking, but the reliable test is the age of the house rather than the street it is on.
