A 1630 carving in a backyard.
Wikipedia says the hamlet's name reflects its spot just south of the Village of Farmingdale; a South Farmingdale station on the LIRR Central Branch opened in 1873, closed in 1898, reopened in 1936 and closed for good in 1972. In 1961 a wooden figure later attributed to the Zulu or another Nguni group, radiocarbon-dated to about A.D. 1630, was found buried in a residential backyard here. The CDP covers 2.2 square miles.
The Census Bureau's latest five-year survey counts about 4,700 homes, with a median year built of 1956. 67% went up in the 1950s, 3% before 1940, and 5% after 1980. 95% are single-family detached houses, and 95% are owner-occupied.
So a typical house here has drain and water lines around 70 years old unless they've been replaced. Slow drains in several fixtures, a gurgling floor drain or rusty water from one tap are signs to have the main line and supply piping checked.
Oil to gas means new gas piping.
The ACS shows 53% of homes heat with utility gas and 40% with fuel oil. Switching means properly sized gas piping to the new equipment, and often to the water heater, range and dryer. We do the gas line work. We don't sell or deliver oil.
On the sewer.
Nassau County's health department lists South Farmingdale's sewers under the Nassau County Department of Public Works (516-571-6841). A backup that stops at your house is usually in your own line to the street; we clear it and repair or replace the line. If neighbors are backed up too, call the county at 516-571-6841.
Flood risk.
Laying FEMA's current flood map over the Census boundary, about 3% of South Farmingdale is in the high-risk (1% annual chance) flood zone (2.9% in zone AE; shares of the Census area, water included). On a sewered street, a backwater (sewer check) valve on your house sewer line can keep a street-sewer backup from coming in through basement floor drains. We install them. If your water heater or gas appliances ever sat in flood water, have them checked before relighting.
Water: South Farmingdale Water District.
EPA's service-area map puts essentially all residents on the South Farmingdale Water District; your bill is the final word. In EPA's UCMR 5 testing, the main supplier reported no PFOA or PFOS. For a leak at the curb or in the street, call your water supplier. For anything on your side of the meter, call us.
Permits.
South Farmingdale is an unincorporated hamlet, so plumbing permits go through the Town of Oyster Bay Department of Planning and Development.
