What Is Kitec Plumbing?

Kitec is a type of flexible plastic piping that was widely installed in Ontario condos, townhouses, and houses from roughly 1995 to 2007. Marketed as a cheaper and faster alternative to copper, it was embraced by developers across the GTA — and it ended up in tens of thousands of homes.

The system uses cross-linked polyethylene (PEX) tubing — typically blue for cold water and orange for hot water — with a thin aluminum layer sandwiched between the inner and outer walls, connected by brass compression fittings.

It was sold under several brand names. If you see any of the following stamped on fittings or pipes, you're looking at Kitec:

XPA / Kitec XPA

Why Is It a Problem?

The core issue is the brass fittings. They contain high levels of zinc, which corrodes over time through a process called dezincification. As the fittings break down, two serious problems can develop:

Blockages & reduced water pressure
Corrosion builds up inside the pipe, restricting flow and causing noticeable pressure drops throughout the unit.
Leaks, bursts & water damage
Weakened fittings can fail suddenly, causing leaks or complete pipe bursts — flooding that can damage your unit and the units below.
Insurance problems
Many insurers will charge significantly higher premiums — affecting both your coverage and your ability to sell or refinance.
Important
The hot water pipes are especially vulnerable — they were only rated for temperatures up to 82°C, but many heating systems run hotter. Deterioration often happens from the inside out, making it impossible to spot until a leak occurs.

How to Spot It

Since plumbing mostly runs behind walls, the best places to look are areas where pipes are exposed. Here's where to check during any showing or inspection:

Under kitchen & bathroom sinks
Look for the distinctive orange (hot) and blue (cold) flexible pipes where they exit the wall or cabinet.
Near the hot water tank or mechanical room
Check what connects to the tank. Orange and blue flexible piping connecting to it is a clear indicator.
Inside the electrical panel door
A yellow sticker reading "Caution: This building has non-metallic interior water piping" is a tell-tale sign — Kitec can't be used as an electrical ground.
On the fittings themselves
Look for the words "Kitec," "KTC," or any of the brand names listed above stamped directly on the brass fittings.
Pro tip: Watch for white corrosion on brass fittings or dark spots and blisters on the pipe itself — these are signs the system is beginning to fail. A qualified home inspector or licensed plumber can confirm Kitec definitively.

Replacement Costs

Replacing Kitec with copper piping is the standard fix — and the cost isn't trivial. Here's what you can expect to pay in Toronto:

1-Bedroom Condo
$5,000 – $6,500
Standard layout, 1 bath + kitchen. Costs rise with complex finishes or ceilings.
2-Bedroom Condo
$8,000 – $10,500
2 baths + kitchen. Mid-range estimate for a typical downtown unit.
3-Bedroom / Complex
$12,000 – $15,000+
Larger units, premium finishes, or unusual layouts can push costs higher.

The frustrating reality: the cost almost always falls on the individual unit owner — whether you arrange and pay for the work yourself, or the condo corporation coordinates a building-wide replacement and sends you the bill. Either way, it's your expense.

What to Do

Whether you're buying or already own a unit with Kitec, here's how to protect yourself:

If You're Buying

1
Request the status certificate
If management is aware of Kitec, it must legally be disclosed here. Have your lawyer review it carefully before waiving conditions.
2
Look for the pipes during your showing
Check under the kitchen sink, bathroom vanities, and near the hot water tank. Orange and blue flexible pipes are the giveaway.
3
Hire a home inspector
Especially important for buildings from this era. A licensed inspector or plumber can confirm presence definitively.
4
Confirm insurance coverage before closing
Contact your insurer before you commit. Some won't cover properties with active Kitec at all — better to know early.
5
Factor the cost into your offer
If Kitec is present and unreplaced, use it as a negotiating point. A credit or price reduction of $5,000–$10,000+ is reasonable depending on unit size.

If You Already Own

1
Watch for early warning signs
White corrosion on brass fittings, dark spots or blisters on the pipe, or sudden drops in water pressure are all red flags. Call a plumber if you notice any.
2
Get replacement quotes
Especially if you're planning to sell, refinance, or renew your insurance. Knowing your exposure ahead of time prevents unpleasant surprises.
3
Disclose when selling
RECO considers Kitec a material fact that must be disclosed to buyers. Non-disclosure can expose you to legal liability after the sale.
