Kitec Plumbing in Waterloo
If your home was built between 1995 and 2007, it might contain Kitec plumbing—an outdated material now causing major concerns for homeowners across the Waterloo region. Once praised as a convenient and cost-effective substitute for copper, Kitec plumbing has since gained a reputation for premature failures that can cause major leaks, water damage, and expensive repairs.
At Dunn Heating and Air Conditioning, we specialize in full Kitec plumbing system replacements, using modern, code-compliant materials that provide long-term reliability. Our licensed plumbing professionals have helped hundreds of homeowners throughout Waterloo and the surrounding area upgrade from vulnerable Kitec systems to durable, modern alternatives.

Our Kitec Plumbing Replacement Process
1
We start by identifying all Kitec plumbing throughout your home. Our licensed technicians inspect visible pipes under sinks, behind toilets, near water heaters, and in utility areas. We also check inside walls, ceilings, and other less accessible places where Kitec plumbing may be hidden.
2
Next, we create a customized replacement plan based on your home’s layout and plumbing needs. The plan outlines which areas will require access, the replacement materials to be used, and the expected project timeline.
3
To protect your home, we carefully cover or relocate furniture and belongings near work areas. We set up safe, clear pathways for our technicians and use containment measures to reduce dust and debris. Our team will also work with you to schedule convenient water shutoff times.
4
We then carefully remove all Kitec plumbing, creating minimal access points where necessary. Our technicians work methodically to reduce disruption and properly dispose of all removed materials according to local guidelines.
5
Once removal is complete, we install new, high-quality plumbing materials that meet or exceed today’s building standards. Most projects use either PEX or copper piping, depending on your home’s specific needs and your preferences. All connections are securely completed, and the new system is fully integrated with your existing plumbing.
6
After installation, we test every water outlet, fixture, and appliance to verify smooth water flow and reliable performance. We then restore all access points to leave your home clean and fully functional.

FAQS About Replacing Kitec Plumbing
What is Kitec Plumbing?
Kitec plumbing refers to a type of piping system commonly installed in Canadian homes between 1995 and 2007. This system uses flexible plastic tubing with an aluminum core, typically colour-coded orange for hot water and blue for cold water, along with brass fittings labelled “Kitec” or “KTC.” Originally promoted as a budget-friendly and corrosion-resistant alternative to copper, Kitec plumbing has since been identified as highly unreliable.
Exposure to hot water accelerates the corrosion of the brass fittings due to a process called dezincification, leading to weakening and eventual failure. The pipes themselves can experience mineral buildup, which restricts water flow and places added pressure on the compromised fittings.
Following a class-action lawsuit in 2005, Kitec piping was withdrawn from the market by 2007. Despite this, many homes across the Waterloo region still have Kitec systems in place. Insurance providers, home inspectors, and plumbing professionals now recommend full replacement of any Kitec plumbing found in homes.
What are the Signs that It’s Time for Replacing Kitec Plumbing?
Even without visible leaks, there are several signs your Kitec system may be at risk and should be replaced:
- Orange or blue tubing visible under sinks or near water heaters with markings like “Kitec,” “KTC,” “IPEX,” or “AQUA”
- Corrosion or white buildup on brass fittings at connections
- Noticeable reduction in water pressure either throughout the home or at specific fixtures
- Discoloured or murky water, sometimes containing dark flecks
- Small pinhole leaks appearing in exposed piping
- Strange noises, such as banging or whistling, while running water
- Fluctuations in water temperature during showers or faucet use
- Continuous running water indicated by the water meter when all fixtures are off
- Water stains, damp patches, or mould appearing near plumbing lines inside walls or ceilings
- Home construction or renovations done between 1995-2007, especially in new housing developments
- Notifications from your insurance company about Kitec plumbing concerns
- Preparing to sell your property and wanting to avoid potential inspection issues
Even if you aren’t seeing any of these symptoms, the presence of Kitec plumbing alone makes replacement a wise decision. Dunn Heating and Air Conditioning can provide a detailed inspection and create a customized plan to upgrade your home’s plumbing.
