Our Kitec Plumbing Replacement Process
1
At Limcan Certified Heating and Air Conditioning in Oshawa, our process begins by locating all Kitec plumbing materials throughout your property. Our licensed professionals inspect visible piping near sinks, toilets, water heaters, and utility rooms. We also investigate harder-to-reach spaces, such as within ceilings and walls, where Kitec piping is often hidden.
2
Next, we craft a customized replacement strategy based on your home’s structure and specific plumbing needs. This plan outlines which sections require access, what new materials will be used, and how long the full replacement should take.
3
Before work begins, we safeguard your furniture and belongings by covering or temporarily moving them away from the work zone. Our technicians create clear, protective pathways through your home and set up barriers to control dust and mess. We’ll coordinate with you in advance to schedule temporary water shutoffs as needed.
4
Our team then carefully removes the existing Kitec piping, working room by room to limit disruption. Strategic access points are created in walls or ceilings as needed, with efforts made to keep these openings as small and neat as possible. All removed materials are handled and discarded according to local disposal guidelines.
5
We then install new plumbing that adheres to today’s building standards. Most homes benefit from durable copper or flexible PEX piping—our experts will help you choose the right fit. Every connection is tested and sealed to ensure compatibility with your home’s plumbing setup.
6
Finally, we inspect each fixture and water outlet to verify performance and pressure. Once we’ve confirmed everything is running smoothly, we patch and restore any areas opened during the installation process to return your home to its original condition.

FAQs About Replacing Kitec Plumbing
What is Kitec Plumbing?
Kitec plumbing is a composite piping system that was commonly installed in Canadian homes between 1995 and 2007. These pipes consist of layered plastic and aluminum and are usually colour-coded—orange for hot water and blue for cold. The system also includes brass fittings typically stamped with “Kitec” or “KTC.” At the time, Kitec was marketed as a modern, budget-friendly alternative to copper piping.
Over time, however, Kitec plumbing has shown serious reliability issues. The brass fittings often corrode due to dezincification, especially when exposed to heat, leading to leaks and eventual failure. The pipes themselves can accumulate mineral deposits that reduce water pressure and strain the already weakened joints.
By 2005, a class-action lawsuit had been launched, and production of Kitec was discontinued in 2007. Despite this, many homes in Oshawa and the surrounding area still contain this flawed system. That’s why plumbing experts, insurers, and real estate professionals now recommend full Kitec replacement. At Limcan Certified Heating and Air Conditioning, we provide expert removal and replacement services to help homeowners avoid future plumbing failures.
What are the Signs that It’s Time to Replace Kitec Plumbing?
Even in the absence of active leaks, there are several telltale signs that your home’s Kitec plumbing system may be failing and should be replaced soon:
- Bright orange or blue tubing visible near water heaters, under sinks, or behind appliances, often labelled “Kitec,” “KTC,” “IPEX,” or “AQUA”
- White scale buildup or signs of corrosion on brass pipe fittings or valves
- Noticeable drop in water pressure either throughout the home or at certain outlets
- Water that’s discoloured, slightly yellow, or contains black grit or debris
- Tiny leaks or moisture around pipe joints or lines throughout the house
- Strange noises like whistling, banging, or knocking occur when water is turned on
- Water temperature shifts unexpectedly during showers or when using faucets
- The water meter continues to show usage even when all plumbing fixtures are shut off
- Stains, dampness, or mould forming on walls or ceilings near plumbing lines
- Your home was built or extensively renovated between 1995 and 2007 (especially in planned communities)
- You’ve been advised by your insurer about limits or exclusions related to Kitec plumbing
- You’re preparing to list your home for sale and want to avoid costly surprises during inspection
Even if you haven’t noticed any of these issues yet, the presence of Kitec plumbing in your Oshawa home is enough reason to act. Limcan Certified Heating and Air Conditioning offers complete assessments and can recommend a customized replacement strategy to help protect your property long-term.
