Plumbing in Boston: what locals should know
Water quality
The soft water in Boston is a plus for plumbing longevity. Water heaters last longer and pipes stay cleaner. Focus your plumbing budget on other priorities like pipe material and drainage.
Freeze risk
In Boston, pipe freezing is a moderate-to-high risk during the coldest months. Make sure you know where your main water shutoff valve is — quick action when a pipe bursts can save thousands in damage.
Material recommendation
In Boston's cold climate, PEX piping offers a key advantage: it can expand slightly when water freezes inside, making it more resistant to burst pipes than rigid copper or CPVC.
Local tip
Older homes in Boston (pre-1970) often have galvanized or cast iron drain pipes that deteriorate over decades. A camera inspection ($150-300) can reveal hidden corrosion before it causes a major leak or backup.

In Boston, verify your plumbing work contractor pulls the permit themselves — never pull it in your own name. If they ask you to pull the permit, they may not be properly licensed to do the work.

Modern codes have changed significantly since these homes were built — any work that triggers inspection should be priced with code upgrades included.
