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.
