South Huntington Water District soft water and a townhouse-heavy housing mix shape these jobs. Parent: Melville. Service: water heater repair and installation.
Soft South Huntington numbers
South Huntington's May 2026 report on 2025 water lists total hardness 2.7–54.6 mg/L — soft — so scale rarely kills tanks here. Age, anodes, dip tubes and fittings do. District inventory: no lead service lines; 343 customer galvanized and 394 unknown of 17,547. Emergencies: (631) 427-8190. Dix Hills Water District streets: (631) 421-1812. The district maintains to the property line; meter pits and indoor work are yours/ours.
Townhouse heaters
Twenty-three percent of homes are attached townhouses; 15% sit in buildings of five or more units. Each unit usually has its own tank. Shut the cold valve on top of a leaker and kill gas/power before water reaches a neighbor. Shared building equipment stays with the association.
Oil minority, gas majority
Fourteen percent oil; 73% utility gas; 9% electric. Oil-to-gas adds a gas tank and piping (National Grid conversions 1-877-696-4743). Average owner household 2.75 people; median 6.4 rooms — smaller than North Bay Shore, different sizing conversation. Town of Huntington permits required.
1980s–2000s originals aging out
Thirty-five percent of homes rose since 2000 and another 17% in the 1980s–90s. Many original tanks are at typical end of life. Rumbling usually means sediment — flush first.
