Backflow Prevention & Testing in NYC
Every building in New York City that has a backflow prevention device is required by law to have it inspected at least once every 12 months. Missing your annual test can mean big fines.
Most property owners find compliance easy—we are experts in testing, installation, and repair.
What is Backflow?
Backflow happens when dirty or contaminated water flows in the wrong direction through pipes into the clean water supply or even into the city water system. This can happen if there's a sudden drop in water pressure.
Think of it like harmful chemicals, waste, or germs, so protecting against it is essential.
A backflow prevention device is a special valve installed on your building's water line that only allows water to flow in one direction—keeping clean water safe.
Who in NYC Needs Backflow Protection?
Many properties in NYC are required to have backflow prevention device testing, including:
- Apartment buildings and mixed-use buildings
- Commercial offices and retail stores
- Buildings with pools, fountains, or irrigation sprinklers
- Properties with water treatment systems or boiler equipment
- Medical, dental, and healthcare facilities
- Laundromats, dry cleaners, car washes, and food prep businesses
- Schools, colleges, and industrial buildings
- Any building the NYC DEP says is at risk
If you have received a letter from the city or DEP, or if you are not sure, Ashokan can help you understand your requirements.
