Essex homes and their plumbing
Here is how Essex's homes break down by year built, based on Census estimates for the covered ZIP codes: before 1940 7%, 1940–1959 35%, 1960–1979 25%, 1980–1999 21%, 2000 or later 12%. 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 Essex homes
Pre-1960 homes: galvanized pipe and cast iron
42% of homes in Essex'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.
Oil-heated homes
9% 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.
Winter freezes
67% 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.
Apartments, condos and attached homes
Only 42% 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.
