Concord homes and their plumbing
Here is how Concord's homes break down by year built, based on Census estimates for the covered ZIP codes: before 1940 32%, 1940–1959 9%, 1960–1979 19%, 1980–1999 25%, 2000 or later 15%. 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 Concord homes
Pre-1960 homes: galvanized pipe and cast iron
41% of homes in Concord's covered ZIP codes were built before 1960, 32% 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.
Oil-heated homes
20% of occupied homes here heat with fuel oil, far above the national norm. Many of them make hot water with a tankless coil inside the boiler, which runs the boiler all summer. Plumbers often replace the coil with an indirect tank or a standalone water heater when the boiler is serviced or replaced.
Long, hard winters
60% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long New Hampshire winter those are the lines that freeze and split. See frozen and burst pipe repair.
