Replace aging, failure-prone Poly-B piping before it leaks — protect your home and your insurance coverage.
Tell us what’s going on and our team will get back to you shortly.
Don't wait for a burst pipe — or an insurance denial letter — to deal with Poly-B. Polybutylene (Poly-B) piping was widely installed in homes built between the 1970s and 1990s. Decades later, it is known to become brittle and prone to sudden failure at fittings, and many insurers now decline coverage or charge higher premiums for homes that still have it.
Gravity Plumbing assesses your existing plumbing, identifies every run of Poly-B and replaces it with modern copper or PEX piping — as a full whole-home repipe or a targeted partial replacement, depending on what your home needs.
Home sales and insurance renewals are often what surface a Poly-B problem — buyers' inspectors across Vancouver, Burnaby and Richmond routinely flag it during a sale, even in a home with no history of leaks.
Poly-B doesn't always show obvious warning signs before it fails — these are the clues worth checking for.
