Understanding Kitec Plumbing: Issues and What Homeowners Need to Know

Written by EGA Inspection

If you’ve recently discovered Kitec plumbing in your home, you might be wondering what this means for your property and its plumbing system. Kitec plumbing was widely installed in North America during the late 1990s and early 2000s, marketed as a durable alternative to copper. However, as time has shown, Kitec plumbing can pose significant risks to homeowners.

What is Kitec Plumbing?

Kitec plumbing is a type of piping system that combines layers of plastic (PEX) and aluminum. Recognizable by its vibrant colors—often blue for cold water and orange for hot water—Kitec piping was initially praised for being lightweight, easy to install, and resistant to corrosion.

However, it became clear over time that this material has inherent flaws that could lead to serious issues in homes.

Known Issues with Kitec Plumbing

1. Pipe Degradation: The primary problem with Kitec plumbing is its tendency to deteriorate over time. The material can react to water’s high mineral content or oxygen, causing the piping to weaken. This can lead to cracks, leaks, or even bursts, particularly in areas with higher water pressure or where hot water flows frequently.
2. Brass Fitting Corrosion: Kitec systems often use brass fittings, which are susceptible to a process called “dezincification.” This occurs when zinc in the brass corrodes, creating a white powdery buildup that restricts water flow, weakens the fitting, and can cause leaks.
3. Limited Lifespan: While initially advertised with a lifespan of 30-50 years, many Kitec installations have started to fail within a much shorter timeframe—sometimes even less than a decade. This has resulted in costly repairs and replacements for homeowners.
4. Potential for Catastrophic Failure: The combination of pipe degradation and fitting corrosion means that Kitec systems can fail without warning, potentially causing significant water damage.
5. Insurance and Home Value Impact: Due to the well-known risks associated with Kitec plumbing, many insurance companies either charge higher premiums or refuse coverage for homes with this piping. Additionally, the presence of Kitec plumbing can affect your home’s resale value, as buyers may be deterred by the potential costs of replacement.

What Should You Do if You Find Kitec Plumbing in Your Home?

If you discover Kitec plumbing in your home, it’s essential to address the issue proactively to avoid costly damages and complications. Here are our recommendations:

1. Inspect Regularly: Keep an eye on areas where Kitec plumbing is visible, such as under sinks, in basements, or near water heaters. Check for signs of leaks, corrosion, or buildup around fittings.
2. Schedule a Professional Inspection: Consider hiring a licensed home inspector or plumber with experience in identifying Kitec systems. A professional can assess the condition of your plumbing and provide guidance on potential risks and timelines for replacement.
3. Consider Replacement: While it’s an investment, replacing Kitec plumbing with more reliable materials, like PEX-A or copper, can save you from unexpected repairs and potential water damage. Many homeowners choose to replace Kitec plumbing proactively, especially if they plan to sell their home or live in it long-term.
4. Consult with Your Insurance Provider: Inform your insurance company about the presence of Kitec plumbing. Some companies may offer advice or adjustments to your policy based on this information.
5. Be Prepared for Replacement Costs: Replacing Kitec plumbing can be costly, but it’s essential for safeguarding your home. Costs vary depending on the size of your home, local rates, and accessibility, but budgeting for this expense can help avoid financial strain when the time comes.
