Backflow Prevention of New York has specialized in backflow testing, installation, and compliance since 2007. Our licensed master plumber and certified testers serve property managers, building owners, and superintendents across all five boroughs. Annual testing is required. DEP deadlines are fixed. Miss them and you’re looking at violations and fines.
The DEP requires backflow preventers for any property where a cross-connection could let contaminated water flow back into the public supply. Common triggers include:
Higher-hazard properties, such as medical facilities and buildings with fire suppression systems, typically require an RPZ device rather than a DCVA.

Our staff engineer assesses your building’s requirements, prepares DEP design submissions, and oversees installation by our licensed plumber. Whether you’ve received a DEP order or are installing for the first time, we manage the process from site survey to initial test filing.
The reduced pressure zone (RPZ) backflow preventer uses dual check valves and a relief valve to protect against back siphonage. It’s required for high-hazard application, including medical facilities, buildings with chemical feed systems, and properties connected to fire suppression systems.
A double check valve assembly (DCVA) is approved for lower-risk installations where space constraints exist. Our staff engineer determines which device your building’s hazard classification requires.
Every new installation requires DEP design approval before work begins. Our staff engineer prepares and submits all documentation, coordinates with the DEP, and manages revisions until approval is granted. All design submissions are handled in-house.
If you’ve received a DEP order to install, we complete violation-response installations on tight timelines, including all required paperwork and the initial compliance test filing.
New York City requires annual backflow testing for every registered device. Tests must be performed by a licensed backflow testing company and results filed with the DEP. We schedule testing, perform it on-site, and file with DEP as part of a single service, so a failed test doesn’t mean bringing in a second company to fix it.
Backflow preventers that fail annual testing must be repaired and retested before the DEP filing deadline. We diagnose device failures accurately, complete repairs using quality components, and retest on the same visit when the schedule allows. Received a DEP violation for a failed or untested device? We complete required repairs and file the correction to get your building back into compliance quickly.
We repair all major backflow preventer types and carry common components to reduce return visits. Most repairs are complete the same day.
Backflow failures don’t follow business hours. Our team is available 24 hours a day, 7 days a week for urgent backflow preventer repairs that can’t wait for a scheduled appointment. Call (718) 460-4600 and your call will be routed to an on-call technician.
Not every failed backflow preventer valve needs to be replaced. Surface corrosion may need cleaning and adjustment. Severe internal failure or advanced age typically warrants replacement. We assess conditions accurately and give you an honest recommendation.
Our team holds credentials that set us apart as a backflow testing company in NYC. Our staff includes:

A backflow preventer valve stops contaminated water from flowing backward into the public water supply when pressure changes occur in the city’s system. Fire suppression activity, main breaks, and other pressure drops can create back siphonage without a properly functioning device in place. Annual testing confirms the valve is operating correctly.
The DEP requires annual testing be performed by a licensed Backflow Prevention Device Tester. Look for a backflow testing service with certified testers on staff who can also test, repair, and file with the DEP as a single vendor. That eliminates the coordination gaps that delay compliance filing when testing and repairs are split between two companies.
A failed device must be repaired and retested before the DEP filing deadline. Failing to file, whether because the device failed or the test was never scheduled, results in violation and fines. The sooner repairs are completed, the more options you have before the deadline hits.
Our licensed master plumbers and certified testers provide free on-site consultations. We’ll review your compliance status, identify any gaps, and tell you what your building needs.
Annual deadlines don’t wait. Getting ahead of them takes one call.
