What type of pipes are best for homes?

PEX (cross-linked polyethylene) pipes are currently the best choice for most Ottawa homes, offering excellent freeze resistance, flexibility, and cost-effectiveness that's particularly valuable in our climate.

PEX has become the gold standard for residential plumbing because it expands slightly when water freezes, reducing the risk of burst pipes during Ottawa's harsh winters. It's also much easier to install than rigid pipes, requiring fewer joints and fittings where leaks typically develop. The material resists corrosion and scale buildup, maintaining good water flow for decades.

Copper pipes remain an excellent premium option and are still preferred by many homeowners for their proven 50+ year lifespan and antimicrobial properties. However, copper costs significantly more than PEX and requires skilled soldering for installation. In Ottawa's older homes, you'll often find copper that's performed well for decades, though it can be susceptible to pinhole leaks in certain water conditions.

For Ottawa homes specifically, PEX's freeze resistance is a major advantage. Our temperature swings and potential for power outages make burst pipe prevention crucial. PEX also handles our mineral-rich groundwater well, unlike older materials that might corrode or restrict flow over time.

Avoid older pipe materials if you're renovating - galvanized steel corrodes and restricts water flow, while polybutylene (gray plastic pipes from the 1980s-90s) is prone to failure and should be replaced. Any repiping work in Ottawa requires permits and should be done by licensed plumbers to ensure code compliance.

For your specific situation, factors like your home's age, existing plumbing, and budget will influence the best choice. A plumbing assessment can help determine whether selective replacement or whole-home repiping makes more sense.
