Part of Greater Massapequa.

Wikipedia describes North Massapequa as part of the Greater Massapequa area anchored by Massapequa, covering 3.0 square miles, all land; the Bethpage State Parkway begins at its interchange with the Southern State Parkway here.

The Census Bureau's latest five-year survey counts about 6,400 homes, with a median year built of 1956. 68% went up in the 1950s, 6% before 1940, and 6% after 1980. 94% are single-family detached houses, and 95% are owner-occupied.

So a typical house here has drain and water lines around 70 years old unless they've been replaced. Slow drains in several fixtures, a gurgling floor drain or rusty water from one tap are signs to have the main line and supply piping checked.

Oil to gas means new gas piping.

The ACS shows 53% of homes heat with utility gas and 39% with fuel oil. Switching means properly sized gas piping to the new equipment, and often to the water heater, range and dryer. We do the gas line work. We don't sell or deliver oil.

On the sewer.

Nassau County's health department lists North Massapequa's sewers under the Nassau County Department of Public Works (516-571-6841). A backup that stops at your house is usually in your own line to the street; we clear it and repair or replace the line. If neighbors are backed up too, call the county at 516-571-6841.

Flood risk.

Laying FEMA's current flood map over the Census boundary, about 13% of North Massapequa is in the high-risk (1% annual chance) flood zone (13.4% in zone AE; shares of the Census area, water included). 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. If your water heater or gas appliances ever sat in flood water, have them checked before relighting.

Water: South Farmingdale Water District.

EPA's service-area map puts about 99% of residents, with a small edge on the Massapequa Water District on the South Farmingdale Water District; your bill is the final word. In EPA's UCMR 5 testing, the main supplier reported no PFOA or PFOS. For a leak at the curb or in the street, call your water supplier. For anything on your side of the meter, call us.

Permits.

North Massapequa is an unincorporated hamlet, so plumbing permits go through the Town of Oyster Bay Department of Planning and Development.

Local reference points: the Bethpage State Parkway / Southern State Parkway interchange.

Questions

North Massapequa plumbing FAQ

Do you cover all of North Massapequa?
Yes, all of North Massapequa (ZIP 11758, 11762, 11783), plus the neighboring communities listed below.
Sewage came up through my basement floor drain. Who do I call?
If it's only your house, the blockage is usually in your line to the street: call us. If neighbors have it too, the public sewer may be backed up: call the county at 516-571-6841.
Can a backwater valve keep sewage out of my basement?
That's what it's for. A backwater (sewer check) valve goes on your house sewer line and closes when the street sewer backs up, so sewage can't flow back in through floor drains and low fixtures. It has to be kept clear and checked from time to time to keep working. We install them. Call (631) 644-2084.
Is my house in the flood zone?
About 13% of North Massapequa is in FEMA's high-risk zone. FEMA's Flood Map Service Center will show your exact address.
Who supplies my water?
EPA's service-area map puts about 99% of residents, with a small edge on the Massapequa Water District on the South Farmingdale Water District. Your bill says which. For leaks at the curb or meter, call the supplier; inside the house, call us.
Can you handle the gas piping when I switch from oil to gas?
Yes, we install and repair gas lines for heating equipment and appliances.
When can I reach you in North Massapequa?
