What Is Backflow Testing?

Backflow testing is a critical process that ensures your drinking water remains clean, safe, and free from contamination.

Backflow happens when water flows in the opposite direction of its intended path, often due to a sudden change in water pressure. This reversal can allow contaminants — such as chemicals, fertilizers, or other pollutants — to enter your property’s drinking water supply.

To prevent this, properties are equipped with backflow prevention devices, which keep the water flowing only one way. Backflow testing is performed annually by certified professionals to check that these devices are working properly and to ensure compliance with New York City Department of Environmental Protection (DEP) regulations.

By scheduling regular backflow testing, you not only protect the health and safety of your family, tenants, or employees, but you also stay compliant with local water safety requirements.
