Backflow Testing, Installation, Repair and Maintenance
Backflow testing, a process used to test plumbing systems to ensure drinking water is not being contaminated, is a necessity for multi-family residential properties as well as commercial properties. Municipal codes often require a backflow prevention device at each cross-connection point found within a commercial plumbing system. A backflow prevention device protects potable water supplies from contamination or pollution due to backflow. For property owners, maintaining backflow prevention devices is crucial.

At DRF, our skilled and experienced plumbers and cross-connection control device inspectors (CCCDI) can ensure your property is code-compliant and that the water supply is safe for tenants and customers.
DRF’s experts can also provide backflow testing on a wide array of reduced pressure zone (RPZ) systems.
Who Needs Backflow Prevention Devices?
The plumbing systems that often require a backflow prevention device are hospitals, apartments, condominiums, foodservice establishments and commercial buildings. Essentially, most multi-unit buildings, whether commercial or residential, require backflow prevention devices. In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. RPZ devices work similarly to backflow prevention devices, but have two independent check valves. While both devices work to keep the water supply safe, only an RPZ device is designed to protect the public water supply by disposing of any contaminants if any of the check valves malfunction.
