Middle River homes and their plumbing
Here is how Middle River's homes break down by year built, based on Census estimates for the covered ZIP codes: before 1940 3%, 1940–1959 26%, 1960–1979 19%, 1980–1999 27%, 2000 or later 26%.

What goes wrong in Middle River homes
Oil-heated homes
12% 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.
Pre-1960 homes: galvanized pipe and cast iron
29% of homes in Middle River's covered ZIP codes were built before 1960. 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.
Winter freezes
47% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a cold Maryland winter those are the lines that freeze and split. See frozen and burst pipe repair.
