Poly B Replacement Calgary — Protect Your Home
Polybutylene (Poly B) piping can fail without warning. R N T Plumbing and Heating replaces Poly B pipes across Calgary with durable PEX or copper — protecting your home and keeping you insured.
What to Expect
Poly B (polybutylene) piping was installed in many Calgary homes built between 1978 and 1995. Over time, chlorine in the water supply causes micro-cracks inside the pipe wall — leading to sudden, hidden leaks that can cause major water damage.
R N T Plumbing and Heating replaces Poly B piping with durable, code-compliant PEX or copper throughout your home. We work efficiently to minimize disruption, provide documentation for your insurance, and back every repipe with our 5-year warranty on labour and parts.
Because Poly B was widely used in Calgary homes built during the city's rapid growth in the 1980s and early 1990s, thousands of local homeowners are sitting on piping that's now well past its safe service life. We make the repipe process as smooth as possible — protecting your belongings, working efficiently, and restoring water each day so you're never left without it overnight.
We provide the documentation your insurer needs, and we use durable PEX or copper installed to current Alberta code. Once the repipe is complete, you can relax knowing your plumbing is safe, insurable, and backed by our 5-year warranty on labour and parts.

"I manage several properties in Calgary. I have used several different plumbing companies over the years and by far R N T Plumbing has been the best Most recently another company came in because 3 out of 4 sinks had no water. They said all 3 faucets had to be replaced. I decided to get a second opinion from R N T and sure enough no need for replacement, just a part. Saved me over $2000. Such a great team, friendly, very responsive and they want to help, not just make money. Thank you R N T."

"If you need a plumber, look no further than R N T plumbing and Heating. Rob provided absolute top-tier service. He was honest about what actually needed to be fixed, didn't try to upsell me on unnecessary parts, and he was incredibly respectful of my home. The boiler now works perfectly, and I’m having them come back to revamp my infloor heating, , 5 star company"

"Bobby showed up on time and inspected my hot water heater. I thought I was going to need a replacement that was going to cost me thousands of dollars, and he ended up saving that for me! He also installed a set of shower taps and had to run some new lines. He was professional and courteous and when I need his help again, I know he will be there, on time, professional and clean up after himself."

Frequently Asked Questions
How do I know if I have Poly B pipes?
Poly B is usually grey plastic pipe with copper crimp rings, often visible near your water heater or manifold. If your home was built between 1978 and 1995, it's worth an inspection.
Why should I replace Poly B?
Poly B degrades over time and can leak suddenly with little warning. Many insurers now require replacement to maintain coverage.
How long does a Poly B replacement take?
A typical whole-home repipe takes 1-3 days depending on size and access. We work efficiently and keep disruption to a minimum.
Do you use PEX or copper?
Both are excellent options. We'll recommend the best material for your home based on your plumbing, budget, and preferences.
