Plumbing in Ontario: what locals should know
Water quality
Hard water in Ontario can shorten water heater life and reduce efficiency. Annual tank flushing helps, but a water softener is the best long-term solution for protecting all your plumbing fixtures.
Freeze risk
While freeze events are rare in Ontario, they can catch homeowners off guard. The 2021 winter storm showed that even warm-climate homes need basic freeze protection for exposed pipes and outdoor fixtures.
Material recommendation
For Ontario's hard water, PEX piping is ideal — it doesn't corrode or develop pinhole leaks like copper can in mineral-rich water. It's also the most cost-effective option for whole-house repiping.
Local tip
If your Ontario home was built before 1960, there's a good chance it has original galvanized pipes. These typically last 40-60 years, meaning many are past their lifespan. Watch for discolored water and low pressure as warning signs.
