Nationwide Plumbers is a NYC Licensed Master Plumber, License #2023, serving College Point homes and businesses since 1984. We handle drain and sewer lines, backflow testing, boilers, water heaters, gas piping and 24/7 emergencies. Call 718-748-2727.
College Point sits on a peninsula between Flushing Bay and the East River, which gives it water on three sides and a character that is a little apart from the rest of Queens. The older core, around College Point Boulevard and 14th Avenue, has frame houses going back to the 19th century, when the area was a manufacturing village. Newer brick two-families have filled many blocks since, and the College Point Corporate Park to the south holds warehouses, distributors and light industry.

That mix produces two kinds of calls. Homeowners deal with old frame houses that have been updated piece by piece, plus low streets near the shoreline that see flooding, with MacNeil Park and Powell's Cove on the water. Businesses need backflow testing, commercial drain lines kept clear and gas service that stays compliant. We handle both, with certificates of insurance ready for commercial landlords.

Common plumbing issues in College Point
Annual backflow tests for businesses
Commercial properties with a backflow preventer on the water service need it tested every year, with results filed with the city. Warehouses and food businesses in and around the corporate park often have more than one device. We test, repair or replace failed assemblies, and file the paperwork so you are not chasing notices. Tests can be scheduled outside busy hours.
Old frame houses with patched plumbing
Frame houses from the late 1800s and early 1900s have usually been replumbed in pieces, with some galvanized, some copper and sometimes some older cast iron still in place. Leaks tend to show up where those pieces meet. We look at the whole system, not only the leak in front of us, and tell you what is worth replacing now.
Flooding near the shoreline
Blocks close to Flushing Bay and the East River can see high water in big storms, and basements on low ground take on water from both groundwater and sewer backups. A sump pump handles the groundwater. A backwater valve protects against sewage coming back through floor drains. We help you figure out which you need, or whether you need both.

Plumbing in College Point: FAQ
How often does a backflow preventer need testing?
In NYC, backflow prevention devices must be tested every year by a certified tester, and the results submitted to the Department of Environmental Protection. If the device fails, it has to be repaired or replaced and retested. We handle the test, any repairs and the filing. See backflow testing.
Can you service our warehouse after hours?
Yes. We dispatch 24/7 for emergencies, and for planned work such as jetting, backflow testing or fixture replacement we can schedule early morning or evening visits so your operations and deliveries are not disrupted.
Is it worth repiping an old frame house?
If you are seeing repeat leaks, low pressure or rusty water, a repipe usually costs less over time than chasing individual failures. We inspect the system, show you what is there and give you a written estimate, with financing through Wisetack if you need it.
