Selling a home with Poly B: the disclosure rules in BC and Alberta
Poly B homes sell every day. What gets sellers into trouble isn't the pipe, it's the paperwork about the pipe. The two provinces run different disclosure regimes, and the courts have made one thing very clear: silence is not a strategy.
The 30-second answer
In BC, answer the Property Disclosure Statement truthfully, and don't imagine that striking it out protects you: the Court of Appeal has held a crossed-out form can itself be a misrepresentation. In Alberta there's no standard disclosure form, but sellers must disclose known material latent defects, and known Poly B problems can qualify. When in doubt, disclose.
British Columbia: the disclosure statement province
BC resales typically include a Property Disclosure Statement, a standardized form where the seller answers questions about the home, including its plumbing. The PDS is usually incorporated into the contract, which means buyers are entitled to rely on it, and a false answer can ground a misrepresentation claim.1
The case every BC seller should know is Sewell v. Abadian, decided by the BC Court of Appeal in 2025. A seller who knew about an unpermitted addition drew a line through the disclosure statement, filled in no boxes, and wrote only that the property was tenanted and he had never occupied it. The Court of Appeal held that the struck-out form, taken as a whole, amounted to a representation that he knew of no problems, which was false, and the buyer recovered her $300,000 deposit.2 The province's real estate forms were updated in response. The lesson translates directly to Poly B: crossing out the form, or answering the plumbing questions with a shrug you know to be misleading, is not a safe harbour.
Separately, BC's real estate regulator requires disclosure of material latent defects, defects a reasonable inspection wouldn't reveal that make a home dangerous, unfit, or expensive to repair, and licensed agents carry their own duty to disclose ones they know about, regardless of instructions.3
Alberta: no form, same duty
Alberta has no mandatory disclosure statement, which surprises sellers arriving from BC. What Alberta does have is the material latent defect duty: under the rules administered by the Real Estate Council of Alberta, sellers must disclose known defects that a reasonable inspection would not reveal and that make the property dangerous, unfit, or very costly to repair. A seller cannot instruct their realtor to stay quiet about one, and the realtor couldn't comply if they tried.4
So is Poly B a "material latent defect"?
The honest answer: it depends on what you know. Poly B that's visible at the water heater is arguably discoverable by inspection. But knowledge changes the analysis: a history of leaks and repairs, an insurer's refusal or conditions on the home, or known failures behind finished walls all push toward disclosure, because those are exactly the facts a reasonable inspection won't reveal.3 The practical rule real estate lawyers give sellers is simple: if you're constructing an argument for why you don't have to mention it, disclose it. A known fact costs you a negotiation; a concealed one can cost you the deal, the deposit litigation, and more.
The seller's playbook
Find out what you actually have
Ten minutes with the identification guide tells you whether it's Poly B and which fitting type. You can't disclose accurately, or price intelligently, without knowing.
Disclose truthfully, in writing
In BC, answer the PDS plumbing questions accurately. In Alberta, disclose known problems even though no form forces the issue. Paper protects sellers as much as buyers.
Decide: replace, credit, or hold firm
Replacing before listing removes the buyer's biggest lever and the insurance objection entirely. A price credit keeps you out of construction but invites negotiation on the number. Holding firm works in hot markets and costs you the cautious buyers. All three are legitimate; pick one deliberately with real cost numbers in hand.
If you replaced it, weaponize the paperwork
A completion certificate with Red Seal certification and pressure test results turns the renovation into a selling feature: the buyer's insurer gets what it needs on day one.
If you're the buyer
Don't count on the inspection: home inspectors aren't required to identify Poly B, and plenty of purchases close with the buyer unaware.5 Check the address on our home page checker, ask the seller's side directly and in writing, and look at the water heater during the viewing. If Poly B is present, get an insurance quote before removing conditions, since coverage terms are the real cost of the pipe, then negotiate with replacement numbers rather than fear.
Common questions
Can I just sell "as is" and skip the disclosure statement in BC?
You can decline to provide a PDS, and courts treat a true no-PDS sale differently. But Sewell v. Abadian shows the trap: providing a struck-out or half-completed form can itself misrepresent, and the material latent defect duty survives either way. Talk to a real estate lawyer before trying to structure around disclosure.
The buyer never asked about the pipes. Do I still have to say something?
If what you know rises to a material latent defect, yes, in both provinces, asked or not. If the Poly B is simply present and visible with no known problems, the analysis is softer, but the safe and increasingly standard practice is to disclose what you know.
Will Poly B kill my sale price?
It's a negotiating lever, not a death sentence. Industry reporting suggests Poly B homes sell at a discount against updated comparables, roughly the replacement cost plus a hassle premium. Sellers who show up with either a completed repipe or honest disclosure and a realistic credit keep control of that conversation.6
