What goes wrong in Putnam County homes
Oil-heated homes
58% 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
38% of homes in Putnam County's covered ZIP codes were built before 1960, 18% 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
67% 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.
1960s and 70s homes reaching end of life
29% of the housing here dates from 1960 to 1979. Original copper supply lines in those homes are now 45 to 65 years old, and cast iron drains of that age scale up inside and crack. Seized shutoff valves, pinhole leaks and recurring main-line clogs are common calls. A camera inspection shows the condition of the sewer line before anyone digs.
