Why water gets into South Huntington homes
None of South Huntington's built-up land is in FEMA's flood zone, so floodwater from outside is not the main threat to homes here. South Huntington's residential streets are mostly unsewered. For homes here, the risks to know are a cesspool backing up, a wet basement, pipes bursting in the cold and old plumbing leaking inside the walls.
- Sewage coming up a drain. Standard homeowners policies usually exclude sewage backup unless a water-backup endorsement was added, so check yours and photograph the damage before cleanup starts. In South Huntington, 3,374 of 3,442 addresses send their wastewater to a cesspool or septic tank in the yard, with no sewer main mapped past them, and a system that is full or failing has nowhere to send it but back into the house. Cesspool Overflow help in South Huntington
- Water in the basement. South Huntington's groundwater, about 117 ft down on average, is out of a basement floor's reach, so a wet basement means water is getting in from a pipe, a window well or the gutters. Water drains quickly through the ground in South Huntington; a puddle that lingers beside the foundation is worth fixing with a downspout extension or regrading before it reaches the basement.

- A burst pipe. Find the main shutoff before winter, because when a pipe bursts the first minutes decide how much of the house gets wet. Fuel oil heats about 63% of South Huntington's homes, so a missed delivery in a cold week can leave a house without heat long enough for a pipe to freeze and split. Frozen Pipe Burst help in South Huntington
- A leak in a wall or ceiling. Mold can start on wet drywall within a day or two, so a slow leak needs the wall opened and dried, not just the pipe fixed. More than half of South Huntington's houses predate 1970, so many still have original supply and drain lines, where a slow leak can run behind a wall for weeks before it shows.
