Watertown homes and their plumbing

With that many older homes, original galvanized supply pipe and cast iron or clay drains are still common, so leaks, rust and root intrusion come up often.

What goes wrong in Watertown homes
Pre-1960 homes: galvanized pipe and cast iron
45% of homes in Watertown's covered ZIP codes were built before 1960, 31% of them before 1940. Houses that old often still have galvanized steel supply lines that rust closed from the inside, and cast iron or clay sewer pipe that cracks and lets roots in. Weak pressure at upstairs fixtures, brown water after a shutoff and slow drains are the usual clues. Typical fixes are whole-house repiping and a sewer camera inspection.
Long, hard winters
58% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long New York winter those are the lines that freeze and split. See frozen and burst pipe repair.
Natural gas in most homes
56% of occupied homes here heat with utility gas, so gas water heaters, ranges and dryers are common. That means gas line extensions for new appliances, flexible connector replacements and venting checks when a water heater is swapped. If you smell gas, leave first and call the gas utility from outside. See gas line repair.
Apartments, condos and attached homes
Only 43% of homes here are single-family detached houses. In attached buildings a leak or clog often involves a shared stack or a neighbor's unit, so it's worth knowing which lines are yours and which belong to the building or HOA, and where your unit's own shutoff is.
