Kitec Plumbing in Kelowna: What Homeowners Need to Know Before It Fails

Kitec was pulled from the Canadian market in 2005 after years of failure reports, class-action lawsuits, and a $125 million settlement against its manufacturer, IPEX. That settlement closed in 2011, but the pipe is still in the walls of a significant number of Kelowna homes – homes built during one of the fastest growth periods the city has ever seen. If your house went up between 1995 and 2007, or if you bought a home from that era without anyone flagging the plumbing, there is a real chance you have Kitec.

We replace Kitec plumbing in Kelowna on a regular basis. The failure mode is different from poly-B, which degrades slowly from chlorine exposure. Kitec fails at the fittings, not the pipe – the brass connectors dezincify over time, meaning the zinc leaches out of the alloy and leaves behind a porous, sponge-like material that cannot hold pressure. By the time you see a drip, the fitting has usually been in bad shape for months. The water coming through the pinhole is the last thing that happens, not the first.

How to Identify Kitec Pipe

The easiest identifier is colour. Kitec uses orange flexible tubing for hot water lines and blue for cold. Both are layered: an aluminum core with PEX bonded to the inside and outside. The pipe itself is soft enough to bend by hand and does not require a torch to work with, which is part of why it was popular with builders during the construction boom.

Look for text stamped directly on the tubing. The markings you are looking for are “Kitec,” “KTC,” “CSA B137.9/10,” or “ASTM F1974.” The system was also sold under several brand names – AmbioComfort, AQUA, KERR Controls, PlumbBetter, WarmRite, and XPA are all the same product under different labels. If you cannot make out the markings on the pipe itself, check your electrical panel. Homes plumbed with Kitec often have a yellow warning sticker inside the panel door noting the presence of the system.

Check near the hot water tank first. Kitec was used in both domestic water supply lines and in-floor radiant heating systems, so some homes have it in two separate locations. If you have in-floor heat and the house dates from the late 1990s or early 2000s, there is a good chance both systems used Kitec.

Why Kelowna Homes Are Especially Exposed

Kelowna grew fast during the exact window when Kitec was being installed. The Central Okanagan’s population jumped from around 128,000 in 1996 to over 162,000 by 2006, and residential construction kept pace with that growth. Builders were working through housing tracts quickly, Kitec was approved and available, and it was faster to install than copper. The result is a large stock of homes in Kelowna, West Kelowna, and the surrounding area – many of them now 20 to 30 years old – that were plumbed with a product that is no longer manufactured and has a documented failure record.

A house built in 2002 has Kitec that is now 24 years old. That is not ancient, but it is well past the age when dezincification becomes a serious concern.

How Kitec Actually Fails

The pipe itself is not the problem. The aluminum-PEX construction is reasonably durable and flexible, which is why some homes with Kitec have not had visible failures yet. The weak point is the brass fittings used at every connection point – where the pipe meets a valve, a manifold, a fixture supply line, or a coupling.

Brass is an alloy of copper and zinc. When hot water flows through a Kitec system day after day, the zinc in the fittings slowly dissolves into the water. This is dezincification. The fitting does not crack or corrode the way steel does. It turns chalky and crumbles from the inside out. Over time the fitting walls become thin enough that normal water pressure causes a fracture. When that happens, water moves fast. We were called to a home in Kelowna a couple of years ago where a fitting on a second-floor laundry supply line had failed overnight. By 7 a.m. the homeowner found six inches of standing water in the laundry room and water seeping through the ceiling of the room below. The fitting itself looked intact from the outside – you had to squeeze it to feel how soft the brass had become.

Hot water lines fail first and fail faster. Kitec pipe is rated to 82 degrees Celsius, but standard tank water heaters in Canada are often set at or above that temperature, and recirculation systems keep hot water moving through the fittings continuously rather than only when a tap is open. Higher temperatures accelerate dezincification. We have pulled fittings from hot water supply lines that crumbled when we gripped them with a wrench, while cold-side fittings in the same house still felt solid.

The Insurance and Mortgage Problem

This is where things get financially complicated, and it is the reason many Kelowna homeowners end up replacing Kitec under pressure rather than on their own schedule.

Insurance companies across British Columbia have tightened coverage rules for homes with Kitec. Depending on your insurer, the consequences range from premium surcharges to limited water damage coverage to outright policy denial when you go to renew. A number of insurers now require documentation that Kitec has been removed before they will write a new policy on the home at standard rates. If you are buying a home and the inspector finds Kitec, your mortgage lender may also flag it. Some lenders will condition the loan on replacement, or require the seller to hold funds in trust to cover the cost. Neither outcome is easy to deal with mid-transaction.

Selling a home with Kitec in the walls also creates its own problems. A buyer who does their homework will use it as a negotiating point, and the discount they ask for usually exceeds what the replacement would have cost you if you had done it proactively. We have spoken with homeowners who found out about their Kitec during a real estate sale and were caught between a buyer demanding a $20,000 price reduction and a plumber telling them the actual replacement cost was $12,000. Getting it done ahead of time removes that leverage entirely.

What Kitec Replacement Costs in Kelowna

Replacing Kitec in a typical three-bedroom Kelowna home runs between $8,000 and $18,000. That range is wider than what you would see for a poly-B repipe because Kitec was often installed in two separate systems – domestic water supply lines and in-floor radiant heating – and replacing both at the same time is a more involved job.

For a home where Kitec is in the supply lines only, the cost is generally in the $8,000 to $12,000 range depending on the number of fixtures, layout, and how much wall access is needed. Homes with in-floor radiant heating that also used Kitec in the heating loop face higher costs because the radiant system uses a separate manifold, its own set of fittings, and often runs under flooring that cannot be easily accessed. In those situations the total replacement can reach $15,000 to $18,000 depending on the square footage heated and the complexity of the system.

We replace Kitec with PEX, the same material used in the original pipe construction without the aluminum core and brass fittings. PEX handles temperature swings well, is approved for both domestic water and radiant heating applications, and carries a lifespan well beyond what any Kitec system can now be expected to provide. Every job is quoted individually because the layout of every house is different – two homes of the same square footage can have wildly different replacement costs depending on whether the plumbing is accessible from an open basement ceiling or buried behind finished drywall.

What Happens If You Wait

The failure risk is not evenly distributed. A Kitec system where the fittings are still intact and showing no signs of dezincification may go several more years without a problem. But the fittings degrade unpredictably, and there is no inspection method short of actually cutting open the system that tells you how far along the process is. You cannot see dezincification from the outside. A fitting that looks fine and passes a basic visual inspection can still be structurally compromised.

When a Kitec fitting fails inside a wall or above a ceiling, the damage bill compounds quickly. You are paying for the emergency service call, the repipe, the drywall repair, and whatever the water touched before anyone noticed – flooring, subfloor, insulation, and in bad cases, the framing. Water mitigation alone on a moderate flood can run $15,000 to $30,000 before a single pipe is replaced. Then there are the insurance consequences: your claim goes on your record, your premium goes up, and some insurers use a claim as the trigger to demand the Kitec be removed as a condition of renewal.

A planned Kitec replacement on a quiet Tuesday costs between $8,000 and $18,000 and takes two to four days. If the repipe is part of a larger project, our renovation plumbing service handles the full coordination. An emergency repair after a failed fitting on a Saturday night costs more, takes longer, and leaves you with a damage remediation project that can stretch for weeks. The pipe does not care which scenario you prefer.
