What goes wrong in Oswego County homes
Pre-1960 homes: galvanized pipe and cast iron
45% of homes in Oswego County's covered ZIP codes were built before 1960, 30% 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
66% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long New York winter those are the lines that freeze and split. See frozen and burst pipe repair.
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.
Propane service
16% of homes here use bottled or tank propane for heat, typical of areas beyond the gas mains. Propane water heaters, ranges and generators need correctly sized lines and fittings rated for LP. See gas appliance hookups.
