Nationwide Plumbers is a NYC Licensed Master Plumber (License #2023) in business since 1984, with 24/7 emergency service in Westchester Square. We handle commercial plumbing, backflow testing, boilers, water heaters, drains and gas lines. Call 718-748-2727.
Westchester Square is the small commercial hub where East Tremont Avenue, Westchester Avenue and Williamsbridge Road meet, under the elevated 6 train at the Westchester Square-East Tremont Avenue station. Local landmarks include the Huntington Free Library and the historic St. Peter's Episcopal Church. Around the square are storefronts, medical offices and services, with older frame houses, attached homes and small apartment buildings on the side streets toward Westchester Creek.

Because so much here is commercial, our work often involves restrooms, water heaters and backflow devices in shops and offices, along with grease lines for the restaurants and delis. The homes nearby bring the usual older-house calls: sewer laterals, boilers, galvanized pipe and basement drains. We schedule commercial work around business hours where we can and dispatch around the clock for emergencies.

Common plumbing issues in Westchester Square
Backflow devices on commercial water services
Many commercial properties around the square have a backflow preventer on the water service that must be tested every year by a certified tester, with results filed with the city. A missed test can bring a violation, and a failed device has to be repaired before it passes. We test, rebuild or replace the device and file the results.
Water heaters in small offices and shops
Medical offices, salons and food businesses depend on steady hot water, and a small commercial tank tucked in a back room is easy to forget until it fails. We replace tanks with the right size and type for the use, check venting and gas supply, and can install a tankless unit where it fits better.
Mixed-use buildings with old piping
Older two and three story buildings with a store below and apartments above often have galvanized supply lines and cast iron drains shared by both uses. When something fails, it affects the business and the tenants together. We find the problem, fix it with minimal disruption to store hours, and give the owner a written plan for the rest of the piping.

Plumbing in Westchester Square: FAQ
When does our backflow preventer need testing?
Backflow devices generally need to be tested once a year, and after any repair. We perform the test, make any repairs needed to pass, and handle the filing. If you have received a notice from the city, call us with the date and we will schedule around it.
Can you replace the water heater in our office without closing for the day?
In most cases, yes. We bring the replacement unit sized in advance, and a typical swap can be done early in the day. We check venting and gas connections first so there are no surprises. See water heaters.
Do you work on homes near Westchester Square, not just businesses?
Yes. We repair boilers, water heaters, sewer lines and leaks for homeowners on the blocks around the square, with free estimates on replacement work and financing through Wisetack. We dispatch 24/7 for backups, leaks and no-heat calls.
Does a small mixed-use building need a Local Law 152 inspection?
If it has gas piping and is not a one or two family home, yes. We perform the inspection, file the GPS2 with the Department of Buildings and quote any required repairs in writing.
