Wikipedia describes Huntington as the seat of the Town of Huntington; its downtown, known locally as Huntington Village, is old and built up but isn't incorporated. The hamlet covers 7.7 square miles. Heckscher Park, bounded by Main Street, Prime Avenue, Madison Street and Sabbath Day Path, holds the Heckscher Museum of Art and the Chapin Rainbow Theater and has been on the National Register of Historic Places since 1985. Next door, Halesite on Huntington Harbor is named for Nathan Hale, who landed there just before his capture. Huntington's LIRR station is actually in neighboring Huntington Station. Children go to Huntington, Harborfields or Cold Spring Harbor schools depending on the street.
The Census Bureau's latest five-year survey counts about 8,400 homes, with a median year built of 1956. 22% are older than 1940, 7% went up in the 1940s, 33% in the 1950s and 13% in the 1960s; 19% were built after 1980. 81% are single-family detached houses, 11% are two- to four-family houses, and 86% are owner-occupied.
So in most houses the plumbing is 60 to 100 years old. In the pre-war houses near the village, expect galvanized water pipe, cast-iron stacks and clay or cast-iron lines to the street; in 1950s houses, original water heaters are long gone but original drains often aren't.
Heating fuel.
The ACS shows 58% of Huntington homes heat with utility gas and 30% with fuel oil. Switching from oil to gas means new gas piping to the equipment, and often to the water heater, range and dryer. We do the gas line work. We don't sell or deliver oil.
Town sewer in the village, cesspools beyond it.
Laying Suffolk County's sewer-district map over the Census boundary, about 16% of the Huntington CDP is in the Huntington Sewer District, centered on the village around Main Street and New York Avenue. The rest is outside any sewer district, so those homes drain to cesspools or septic systems. The town runs the district: more than 35 miles of sewer mains and 830 manholes flow, mostly by gravity, to the Huntington Wastewater Treatment Plant at 65 Creek Road, which discharges through an outfall in Huntington Harbor; a pump station at the plant serves Halesite along New York Avenue up to Youngs Hill Road. Connecting a house takes a town sewer connection permit, a minimum 6-inch connection, and a Town of Huntington-licensed master plumber with a $5,000 performance bond on file with the town's Department of Environmental Waste Management. On a cesspool street, when every drain slows at once, we clear the line, which tells a pipe problem from a full cesspool; a failing cesspool is a job for a cesspool or septic contractor, since we don't do cesspool work. Since July 1, 2019, Suffolk County hasn't allowed a failed cesspool to be replaced with another cesspool.
Low ground by the harbor.
The low stretch of New York Avenue (Route 110) from Madison Street and Prime Avenue to Mill Dam Road, on the way to Halesite, flooded often when heavy rain met high tide; most of its drainage dated to 1929 until a drainage project added a creek-bypass culvert and new tide gates. In Hurricane Ida on September 1, 2021, the town reported 6.29 inches of rain in six and a half hours and 26 flooding reports; cars, including a police car, were stranded on Creek Road and New York Avenue outside the sewage plant. In 2024 the town received $1 million in federal money to extend sewer lines and shore up the plant against flooding. FEMA's current map puts only about 2.5% of the CDP in the high-risk zone, along the harbor. 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.
Water: Suffolk County Water Authority, moderately hard.
EPA's service-area map puts about 95% of residents on SCWA and about 5% on the Greenlawn Water District (check your bill). SCWA's index puts most of greater Huntington in its Distribution Area 6, with the village core, the Route 110 corridor and the harbor shoreline in Area 5 and some streets in Area 7. Its 2026 report on 2025 water shows Area 6 hardness of 24.8 to 148.4 mg/L, averaging 78.3, and Area 5 averaging 113.6 with readings up to 187.9, which is hard. Expect scale on fixtures and in water heaters; flushing the tank, or a softener, helps. Nitrate averaged about 6 mg/L in both areas (Area 6 high 8.94, limit 10); SCWA lists fertilizer and septic systems among the sources. 1,4-dioxane averaged 0.40 micrograms per liter in Area 6, with one reading of 1.20; New York judges the 1.0 limit on a running average, and the report shows no violation. PFOS and PFOA stayed at or below 4 parts per trillion (limit 10). For a leak at the street, call SCWA at (631) 698-9500.
Permits and licensing: Town of Huntington.
Huntington is an unincorporated hamlet. The town plumbing code requires a Town of Huntington permit to install, repair or modify plumbing or gas piping, and a plumbing license issued by the town to do the work. Owners of one- and two-family homes may do their own plumbing, but not gas piping.
