Should I replace copper pipes with PEX?

PEX is generally a smart upgrade from copper pipes, especially in Ottawa's climate where freeze-thaw cycles can stress copper joints. PEX offers better freeze resistance, lower material costs, and easier installation, making it the preferred choice for most residential repiping projects.

The main advantages of switching to PEX include superior flexibility that reduces the risk of burst pipes during freezing, resistance to corrosion and mineral buildup that commonly affects copper in Ottawa's hard water areas, and significantly lower installation costs. PEX also maintains water temperature better than copper and won't develop pinhole leaks that older copper systems often experience after 20-30 years.

However, copper still has some benefits - it's proven to last 50+ years when properly maintained, has antimicrobial properties, and some homeowners prefer it for aesthetic reasons in exposed areas. The decision often comes down to the age and condition of your current copper system, your budget, and whether you're doing a whole-home repipe or just replacing problem sections.

In Ottawa specifically, most plumbers now install PEX for new work and repiping projects. The material handles our temperature extremes well, and installation typically costs 30-40% less than copper. City of Ottawa permits are required for repiping work, and the installation must meet Ontario Building Code requirements for proper support and protection.

Consider replacement if your copper pipes are over 25 years old, you're experiencing frequent leaks, or you're already doing major renovations. For a whole-home repipe in Ottawa, expect costs between $5,000-$15,000 depending on home size and accessibility. A licensed plumber can assess your specific situation and help you determine if partial or complete replacement makes the most sense.
