"Dick's Hills" to Half Hollow Hills.

Wikipedia's history says settlers traded with the Secatogue for the land in 1699, and the name traces to a local man, Dick Pechegan; "Dix Hills" was in use by 1911. The area was mostly farmland until after World War II. In 1941 developer J. Franklin Bradley moved a ranch house from the 1939 World's Fair "World of Tomorrow" exhibit to his new Dix Hills development. Proposals in the 1950s and again around 2001 to incorporate a village of Half Hollow Hills failed, so Dix Hills is still an unincorporated hamlet. It covers about 15.9 square miles, the Long Island Expressway runs almost straight through the middle, and it borders the Town of Babylon to the south.

The Census Bureau's latest five-year survey counts about 8,100 homes, with a median year built of 1970. 37% went up in the 1960s and 23% in the 1970s; only 14% are older than 1960 and 26% were built after 1980. 95% are single-family detached and 96% are owner-occupied.

Larger houses on larger lots mean longer runs: a long main drain out to the cesspool or septic system, and long supply and gas lines. Many of these homes are now 45 to 65 years old, about when original water heaters, fixture valves and drain lines start to show it.

Heating fuel.

The ACS shows 60% of Dix Hills homes heat with utility gas and 35% 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.

Cesspools and septic for most homes.

Laying the county's sewer-district map over the Census boundary, only about 3% of the hamlet is inside an active sewer district: the Strathmore at Huntington Sewer District (County Sewer District No. 5). Everywhere else, homes use cesspools or septic systems. When every drain in the house slows at once, it can be roots or a break in the line, or a cesspool that no longer takes water. We clear the line before anyone talks about digging. If it's the cesspool itself, you'll need a cesspool or septic contractor; we don't do cesspool work. Since July 1, 2019, Suffolk County hasn't allowed a failed cesspool to be replaced with another cesspool.

Water: Dix Hills Water District.

The district was formed in 1953 to serve 110 homes near Wolf Hill Road, and is run by the Huntington Town Board. Its spring 2026 report on 2025 water says it serves about 41,000 people from wells in the Glacial and Magothy aquifers and adjusts pH upward with sodium hydroxide to reduce corrosion of mains and household plumbing. It reports meeting all standards except iron: its 2025 table shows iron up to 1,000 micrograms per liter against New York's 300 standard, and the district says the highest level came from Well No. 10-1, which it treats with a sequestering agent. Total hardness ran 1.8 to 51.2 mg/L, so the water is soft, and nitrate ran up to 5.1 mg/L against a 10 mg/L limit. Wells 5 and 8 are out of service until new treatment for 1,4-dioxane (and perchlorate at Well 5) is finished, expected in 2027, and four plants already have carbon filters for VOCs, PFOA and PFOS. The district says no lead service lines have been found to date, and that with most homes built after 1950, the chance of lead service lines is very low. District office: (631) 421-1812. Check your water bill to confirm your supplier; the district covers most, not necessarily all, of the hamlet.

If you want a filter for taste, iron or peace of mind, pick one certified for what you're worried about and sized to the report. We install whole-house and under-sink systems.

Permits and licensing: Town of Huntington, plus the water district.

Dix Hills 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. Work on the water service itself has one more rule: the Dix Hills Water District's handbook says no one, including the property owner, may connect to its pipes or repair or alter the service pipes unless they are a district employee or a plumber bonded with the district and licensed by the Town of Huntington.
