Franklin Square is almost entirely postwar houses on dry, flat ground, so its emergencies are plumbing failures, not floods. Our Franklin Square page has the background, and the emergency plumber page has a general checklist.
No mapped flood zone
Our overlay of FEMA's flood map on the Census Bureau's Franklin Square boundary finds none of the hamlet in a high-risk or moderate-risk flood zone. The hamlet sits near the middle of the old Hempstead Plains, according to Wikipedia. So water on a Franklin Square basement floor almost always comes from inside: a supply line, a water heater or a drain backup. That's good news, because you can usually stop it at the main valve.
Two households, one main
The Census Bureau's latest survey counts 9% of Franklin Square homes as two-family houses and puts the average owner household at 3.19 people. In a two-family house both units usually share one house sewer. If the lower unit's tub or floor drain fills when the upper unit runs water, the shared main is partly blocked. Tell the other unit to stop using water, then call us.
A split pipe or a leaking tank
45% of homes here were built in the 1950s and 16% before 1940, so supply lines and water heaters are often old. A sudden leak means closing the main valve, where the service enters the house. If the leak is at the water heater, also shut off its gas or its breaker.
The water district's side
Most of the hamlet is on the Franklin Square Water District. Its lead service line inventory, filed with the state in October 2025, counts 5,208 service lines. On the district's side, 243 are galvanized and none is lead. On the customer side, 3 are lead and 3,144 are still unknown. The district's 2025 report says a leak detection study of its own system found about 15 previously unknown underground leaks, all repaired. If water is bubbling up at the curb or the meter, it may be the district's. Call them first; once it's shut off, we repair your side.
