Based on Merrick Road, serving Massapequa
Massapequa is our home ZIP. Our office sits on Merrick Road on the East Massapequa side of 11758, about five minutes from most Massapequa streets without traffic. Most of the houses here went up in one burst after World War II, so many of them have the same plumbing at the same age. That shapes most of the calls we get.

Most homes are about 70 years old.
The Census Bureau's latest five-year survey counts about 7,400 homes in the Massapequa CDP. 97% are single-family detached houses, and 97% are owner-occupied. The median year built is 1956, and half of all homes were built in the 1950s alone. Wikipedia's history of the hamlet says its population grew from about 3,500 in 1940 to about 40,000 by 1960. If your house still has its original drain and water lines, they have been working for roughly 70 years. Old drain lines are where slow drains, root problems and main-line backups start.
About a third of homes still heat with oil.
The same survey shows 61% of Massapequa homes heat with utility gas and 34% with fuel oil. When a house switches from oil to gas, someone has to run gas piping to the new equipment, and often to a new water heater, range or dryer too. That piping is plumbing work, and it's work we do.
Your water is soft and naturally corrosive, so it's treated.
The Massapequa Water District serves about 46,000 people from nine wells in the Magothy aquifer, according to its Annual Drinking Water Quality Report. The district raises the pH of the pumped water with sodium hydroxide to cut corrosion in water mains and household plumbing. It also adds polyphosphates to protect pipe surfaces and hold naturally occurring iron in solution. Total hardness in the 2023 report was just 3.0–6.6 mg/L, which is very soft water. In practice that means less scale in water heaters than in hard-water regions. If you see rusty staining, ask about iron. If you want extra filtration, size it to your actual water report, not a generic sales pitch.
South of Merrick Road, water and storms matter.
Named neighborhoods in southern Massapequa include Biltmore Shores, Harbor Green and Bar Harbor. In October 2012, Hurricane Sandy's surge flooded much of Massapequa south of Merrick Road, along the shore and up the canals that reach about a mile inland. Hundreds of houses had to be gutted and rebuilt. If your house was rebuilt after Sandy, some of its plumbing may be much newer than the 1950s average. If it wasn't, check your water heater, gas lines and any low-lying cleanouts after big storm surges. On a sewered street, a backwater (sewer check) valve on the house line closes if the street sewer backs up, so sewage can't come in through low drains. We install them.
Sewer, not cesspool, for most.
Most of Nassau's South Shore is connected to the Nassau County sewer system. A blocked main here is usually a house-to-street sewer line problem, not a full cesspool.
Local landmarks we drive past daily: the Massapequa LIRR station (built 1896), Massapequa Lake, and Sunset Park, home of the Fort Massapeag Archeological Site, a National Historic Landmark.

Questions
Massapequa plumbing FAQ
Do you cover all of Massapequa?
Yes. We cover all of ZIP 11758, including Biltmore Shores, Harbor Green, Bar Harbor and North Massapequa, plus Massapequa Park (11762) next door.
My house was built in the 1950s. Should I worry about the main drain?
Not worry, but check. Half of Massapequa's homes date from the 1950s. If you have slow drains in more than one fixture, gurgling, or a backup in the basement, have the main line cleared before it fails.
Water is bubbling up at the curb or in the street. Is that my problem?
Usually it's the water district's main or service connection. Call the Massapequa Water District first. If the leak is on your side of the meter or inside the house, call us at (631) 644-2084.
Can you run a gas line for my oil-to-gas switch?
Yes. We install and repair gas piping for appliances.
Do you install septic systems?
No. We clear the line from the house to an existing septic tank, but we don't install septic systems, and we don't do cesspool work.
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.
When can I reach you in Massapequa?
We answer calls 24/7. We're open Monday through Saturday and closed on Sunday. Call (631) 644-2084.
