Poly B pipes were installed in many Canadian homes between the late 1970s and 1990s. Although this flexible plastic pipe was once considered an affordable plumbing material, aging Poly B plumbing can deteriorate and fail without much warning.

We can replace Poly B piping with modern PEX pipes or copper, depending on your home, budget and plumbing requirements. Every proposal includes upfront pricing and an estimated schedule so you know what the project will involve before work begins.

A video consultation may allow us to review visible grey plastic pipes, fittings or damaged areas before visiting your property. This helps us prepare for the inspection and answer your initial questions.
A professional plumber examines the accessible plumbing system and confirms whether your home has Poly B. We assess pipe locations, plastic fittings, water lines, fixtures and areas where wall or under-slab access may be necessary. Camera inspections of the sewer or house-to-street line may also be recommended when hidden drainage problems could affect the project.
We explain the condition of the Poly B system and recommend either targeted repairs or full replacement. Your proposal outlines the replacement material, project scope, access requirements, upfront price and expected schedule.
Smaller jobs generally require no deposit or upfront payment. Payment terms for larger projects are discussed during the proposal stage.
Our licensed plumbers remove or disconnect the affected polybutylene pipes and install a new system using PEX pipes or copper. Quality brass fittings or copper fittings are used where appropriate.
When pipes are located behind walls or beneath a slab, we choose practical access points and rerouting options designed to minimize disruption. We can also coordinate drywall repair when wall openings are required.
Hot water tank, water heater and water treatment connections can be incorporated into the project when necessary.
We test the completed plumbing work, including water pressure, hot water delivery and fixture connections. You receive a final walkthrough and information about Lister Plumbing’s one-year workmanship warranty.

The most common materials used to replace Poly B are PEX and copper.
PEX, or cross-linked polyethylene, is a flexible and durable modern solution. It can often be installed with fewer connections than rigid plastic pipes, which may help simplify installation through finished areas. PEX also has a long life expectancy when properly installed and is widely used in residential plumbing systems.
Copper is another proven replacement material. It may be recommended for certain visible sections, mechanical-room connections or areas where rigid piping is preferred.
Our team will explain the advantages of each material and recommend a solution that complies with applicable plumbing code requirements.
Poly B is usually identifiable as flexible grey plastic piping. It may be visible near a hot water tank, beneath sinks, behind access panels, along basement ceilings or inside utility rooms.
Other potential warning signs include:
Previous pinhole leaks
Water stains near plumbing lines
Brittle or discoloured plastic fittings
Inconsistent or high water pressure
Repeated leaks in different areas
Grey pipes connected to copper plumbing
However, a Poly B system can appear normal from the outside while deterioration develops internally. An inspection is the most reliable way to confirm what material is installed and determine whether replacement is advisable.
Chemicals commonly found in municipal water supplies may contribute to the deterioration of Poly B pipes and fittings over time. Heat, water pressure, installation quality and reactions with other chemicals can also affect the condition of the system.
Failures can appear as small pinhole leaks or sudden pipe breaks. Because many Poly B pipes are concealed behind drywall, damage may spread before homeowners notice a problem. This can lead to damaged walls, flooring, cabinetry and personal belongings.
Replacing the entire system can help reduce the risk of repeated leaks and costly repairs. It may also remove a concern for future buyers or insurance companies reviewing the property.
The cost to replace Poly B varies depending on several factors, including:
The size and layout of the home
The amount of Poly B piping present
Accessibility behind walls and ceilings
The selected replacement material
Under-slab pipes or rerouting requirements
Drywall and finishing work
Water heater or filtration-system connections
Lister Plumbing uses upfront pricing with no hidden fees. We provide free quotes for larger projects, and an optional small booking incentive may be available.
Payments can be made by e-transfer, cash or cheque. Smaller jobs generally do not require upfront payment. For larger Poly B replacement projects, payment terms are reviewed during the proposal stage.
Lister Plumbing provides Poly B replacement services throughout:
What is Poly B and why is it a concern for Ottawa homes?
Polybutylene, commonly called Poly B, is a flexible grey plastic pipe used in many homes built from the late 1970s through the 1990s. Chemicals in municipal water supplies, high water pressure, installation conditions and reactions involving plastic fittings may cause Poly B pipes to become brittle or develop pinhole leaks. A failure can damage your home’s plumbing system, walls, flooring and personal belongings.
How do I know if my home has Poly B pipes?
Look for flexible grey plastic pipes near your hot water tank, in the basement, beneath sinks, behind access panels or inside crawlspaces. Because some pipes may be concealed behind walls, a licensed plumber can inspect the system and confirm whether your home has Poly B plumbing.
Do all Poly B systems need full replacement?
Not every Poly B system is in the same condition. However, failures can be difficult to predict, and repairing one section does not prevent another area from leaking later. Many homeowners choose full replacement as a safer long-term solution. We can also recommend sectional replacement when it is appropriate for the property and project scope.
What replacement materials do you use?
We commonly replace Poly B piping with PEX pipes or copper. PEX is a flexible form of cross-linked polyethylene that provides a durable, modern solution for residential plumbing systems. Copper or brass fittings may be used where appropriate. The selected replacement material will depend on the property, pipe routes and applicable plumbing requirements.
Will replacing Poly B require cutting drywall or opening walls?
Some replacement projects require access through drywall, ceilings or other finished surfaces. We plan access points carefully and reroute pipes where practical to keep openings to a minimum. When drywall repair is needed, we can coordinate with qualified repair professionals.
How long does the Poly B replacement process take?
Timelines vary depending on the size of the home, accessibility and whether wall or under-slab work is required. Smaller or sectional projects may be completed more quickly, while an entire system replacement may take several days. Lister Plumbing provides a project-specific schedule estimate with every quote.
What is the cost to replace Poly B piping?
Poly B replacement cost depends on the home’s size, pipe access, replacement material, drywall requirements and whether under-slab rerouting is needed. We provide upfront pricing with no hidden fees. Free quotes are available for larger projects, and smaller jobs typically require no deposit or upfront payment.
Does Poly B replacement affect home insurance or resale value?
Poly B plumbing may be considered a concern by some insurance companies and prospective buyers. Requirements vary by insurer, so replacing the pipes does not guarantee lower insurance premiums or specific coverage. However, documenting a professional Poly B plumbing replacement may remove an identified concern and support the home’s resale value.
Can you complete a partial Poly B replacement to reduce the cost?
Yes, targeted Poly B pipe replacement may be possible when the affected area is limited and accessible. We will explain the cost and trade-offs of a partial repair compared with replacing the entire system. Full replacement may offer greater long-term reliability when Poly B is present throughout the home.
Do you handle under-slab Poly B pipe replacement?
Yes. Lister Plumbing has experience with under-slab plumbing repairs and rerouting. We assess the pipe location and may use camera inspections or other diagnostic methods to recommend the least invasive practical solution.
Will you inspect my main sewer or house-to-street line?
We offer sewer camera and main-line inspections when drainage conditions could affect the replacement plan or indicate other plumbing concerns. This service may be particularly useful in older homes and multi-unit properties.
What warranty do you offer on Poly B replacement work?
Lister Plumbing provides a one-year workmanship warranty on its installations. We use licensed plumbers and quality replacement materials to support reliable, professional results.
Will my hot water tank need to be replaced?
Not necessarily. We inspect the hot water tank and its connections as part of the project planning process. When reconnection, relocation or replacement is required, we can complete electric water heater and hot water tank work as part of the plumbing project.
Do you coordinate drywall repair after replacing the pipes?
Yes. Lister Plumbing focuses on the plumbing work but can coordinate with qualified drywall repair professionals when openings are required. Our goal is to complete the pipe replacement with minimal disruption and leave the work area clean.
How do I book a Poly B inspection or replacement in Ottawa?
