The reason it counts

Galvanized steel was a common supply pipe in Canadian homes built before roughly the 1960s. Its zinc coating protected the steel for a good many years, but once that coating wears through, rust forms inside the pipe. The bore narrows, pressure falls, and the water may run brown after it has sat overnight. Eventually the pipe thins at the threads, which is where most leaks begin.

Homes around Main Street, the streets near Fairy Lake and other early neighbourhoods were built over many decades and renovated in pieces. It is common to find copper in the kitchen and galvanized pipe still hidden in a wall or under the basement ceiling. Insurers sometimes ask about it too, so knowing what you have is useful when renewing a policy or selling.

Steps, in order

1. Look where the water enters. Near the meter, inspect the pipe leaving it. Galvanized pipe is dull grey and joined by threaded fittings.
2. Scratch test. Gently scratch the surface with a key or screwdriver. Copper shows a penny colour; plastic is soft; galvanized steel stays silvery grey.
3. Try a magnet. A fridge magnet sticks firmly to galvanized steel and does not stick to copper, PEX or brass.
4. Follow the runs. Trace exposed pipe across the basement ceiling and to the water heater to see how much remains.
5. Note the symptoms. Low flow on upper floors, rust-tinted water, and leaks at threaded joints all point the same way.

Planning replacement

Replacing all the galvanized supply at once is usually the most economical route, because opening walls and ceilings is a large part of the work. Where a renovation is already planned, that is the ideal moment. Modern replacements are typically copper or PEX, each with its own strengths, and we will explain both. Some owners phase the work, beginning with the most corroded runs in the basement and finishing upstairs later.

Drains are a separate question

Older houses may also have galvanized or cast iron drains. Those age differently and are assessed on their own, often with a camera. If you are also choosing a new water heater as part of a larger project, our circular on tankless versus tank sets out the trade-offs.

Ringing for help

Call us if you find galvanized supply pipe, especially with leaks, rust or poor pressure. We carry out repiping for homes in Central Newmarket and the older streets nearby, and we can replace the main water line where needed. While the walls are open, it can be sensible to rough in connections for a new dishwasher or appliance. Properties on wells, including some just outside town, may need well pump service alongside new piping.
