What goes wrong in Southeastern Connecticut County homes
Oil-heated homes
45% 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
42% of homes in Southeastern Connecticut County's covered ZIP codes were built before 1960, 27% 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
69% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Connecticut winter those are the lines that freeze and split. See frozen and burst pipe repair.
