If your home was built before the 1980s, here's what to keep an eye on.
Galvanized steel supply pipes
Common in older homes, galvanized pipes corrode from the inside, gradually reducing water pressure and sometimes causing discoloured water.
Cast-iron drain stacks
Cast iron is durable but can crack or corrode over decades, especially at joints and horizontal sections.
Clay or older sewer laterals
Older laterals were often made of clay tile or other materials with joints that roots can penetrate.
Lead service lines
Some older Toronto homes still have lead water service pipes. The City of Toronto has information on how to check and on its lead pipe replacement program.
Outdated fixtures and valves
Old shut-off valves can seize, and older toilets and faucets wear out. Updating these is often a simple, worthwhile improvement.
A practical approach
You don't need to replace everything at once. Understanding what you have helps you plan repairs sensibly and avoid surprises.
