Hempstead homes and their plumbing
Here is how Hempstead's homes break down by year built, based on Census estimates for the covered ZIP codes: before 1940 21%, 1940–1959 37%, 1960–1979 29%, 1980–1999 6%, 2000 or later 8%. 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 Hempstead homes
Pre-1960 homes: galvanized pipe and cast iron
58% of homes in Hempstead's covered ZIP codes were built before 1960, 21% 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
16% 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.
Natural gas in most homes
72% of occupied homes here heat with utility gas, so gas water heaters, ranges and dryers are common. That means gas line extensions for new appliances, flexible connector replacements and venting checks when a water heater is swapped. If you smell gas, leave first and call the gas utility from outside. See gas line repair.
Long, hard winters
86% 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.
