Water damage risks in Syosset
Cesspools on the North Shore
Unlike most of central and southern Nassau, much of the North Shore was never connected to sewers, and many Syosset homes still use cesspools. When a cesspool fills or the surrounding soil is saturated, wastewater comes up through the lowest drain in the house.
Split-levels and finished lower levels
Lower levels in split-level and high ranch homes are partly below grade, finished with carpet and drywall and often home to the laundry and water heater. Water spreads fast and hides under flooring.
Hills and ice dams
The ground rises to the north, so runoff collects at the bottom of sloped lots. In hard winters, ice dams on low-slope roofs push water into upstairs ceilings.
Water damage in Syosset right now? Do this first
Shut off the water
In most Nassau homes with a basement, the main valve is on the wall facing the street, next to the water meter. Your water district, village or water company can shut the curb valve if yours fails. The number is on your water bill.
Stay safe around electricity
Do not walk through water near outlets, appliances or the panel. Turn off power at the breaker only from a dry spot.
If drains are backing up
Most of Nassau is on public sewers. If a basement drain backs up, stop using water. If only your home is affected, call a plumber to clear the house line. If neighbors are affected too, also call your sewer authority.
