What goes wrong in Worcester County homes
Pre-1960 homes: galvanized pipe and cast iron
53% of homes in Worcester County's covered ZIP codes were built before 1960, 35% 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
28% 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
71% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Massachusetts winter those are the lines that freeze and split. See frozen and burst pipe repair.
Apartments, condos and attached homes
Only 44% 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.
