Why water gets into North Patchogue homes
North Patchogue sits above Sunrise Highway, away from the Patchogue River corridor that floods, though its properties are largely unsewered. In North Patchogue, flooding is the outside risk, and inside the house the risks are a cesspool backing up, a wet basement, a pipe that freezes and splits and an aging pipe giving way.
- Water coming in from outside. If the water came in from outside, it is a flood claim: photograph the water line and every damaged item before cleanup starts, because the adjuster will ask for them. FEMA's flood zone covers about 3.6% of North Patchogue's built-up land, and homes on those streets with a federally backed mortgage must carry flood insurance. Since 1978, policyholders in ZIP 11772 have filed 824 federal flood insurance claims, a record of flood water reaching buildings in this ZIP. Look up your street. Storm Damage Restoration help
- Sewage coming up a drain. Anything porous the sewage reaches, such as carpet or drywall, usually has to come out, and what stays has to be disinfected before it is dried. Homes in North Patchogue treat their own wastewater in a cesspool or septic tank, so when the system is full, slow drains and gurgling pipes come before sewage in the lowest drain. Cesspool Overflow help in North Patchogue
- Water in the basement. Groundwater in a basement returns after a pump-out unless a sump pump keeps up, so drying the walls and floor matters as much as removing the water. Under North Patchogue, the water table averages 18 ft deep but sits much closer to the surface on some streets, and those are the basements that can take on water from below. Basement Flooding help in North Patchogue
- A burst pipe. If a pipe bursts, shut the main water valve first; a split supply line keeps running at full pressure until someone does. In a hard freeze the pipes that split are the ones in outside walls and crawlspaces, and North Patchogue's houses, about 64 years old on average, have plenty of them. Frozen Pipe Burst help in North Patchogue
- A leak in a wall or ceiling. An old shutoff valve can seize, so find the main valve and test that it turns before the day you need it. About 63% of North Patchogue's homes were built before 1970, and pipes from that era, galvanized steel and cast iron, corrode from the inside until a joint or a section gives way.
