Three water suppliers split the hamlet; all run soft water. Parent: East Massapequa. Service: water heater repair and installation.

Read the bill before blaming hardness

Liberty Merrick covers most streets (hardness ~1.6–19.3 mg/L, 1-877-426-6999). South Farmingdale Water District covers a smaller share ((516) 249-3330) with soft, low-mineral water and iron-removal plants noted in its AWQR. Massapequa Water District pockets ((516) 798-5266) report similarly soft numbers and list a public service-line inventory viewer. Soft water shifts failures toward anodes and fittings, not scale crust. Flush annually either way.

Oil third, gas majority

Thirty-three percent oil; 57% utility gas. Oil-to-gas work adds a gas tank, gas piping and vent under Town of Oyster Bay permits. National Grid conversions: 1-877-696-4743. We do not service oil equipment. Remodeled south-end houses after Sandy sometimes already have newer heaters elevated above the old basement flood line.

South-end flood placement

FEMA high-risk is about 24% of the CDP at the bay end. Saltwater-soaked heaters stay off until inspected; controls and burners usually need replacement. We discuss elevation and shutoffs on those streets. North of the flood band, standard basement settings apply. Backwater valves are a sewer topic, not a heater topic, but the same storm can trigger both calls.

Inventory footnotes

Massapequa WD: 1 lead line in 13,526 per NYSDOH. Liberty Merrick: customer-side lead and galvanized counts district-wide. A foundation wet spot may be the service line — call the supplier for the curb side first.

Matching the tank to the supplier

Soft water is common across Liberty, South Farmingdale and Massapequa WD streets, but emergency phones differ. Bring the bill so we know who owns the curb. Elevated stands after Sandy are common on canal-adjacent basements; we reuse sound stands when they fit the new tank. Call (516) 360-9493.
