Backflow Device Testing, Installation, & Repair

Property owners and managers are responsible for the quality of water that is piped through their buildings. If water in the building becomes contaminated, it could threaten the health and safety of residents, tenants, and on-site teams.

If your property has any applications that could pose a contamination risk to the water supply, such as commercial boilers, pools, irrigation systems, or fire sprinkler systems, you are required to have backflow prevention devices installed and the devices need to be tested every year by a certified plumbing contractor. Your water utility company will send out notices to remind you of the annual testing. Ignoring these notices could result in the water and / or sewer service to be suspended.

By law, only firms registered under a licensed Master Plumber can perform the installation, repair, or testing of backflow prevention assemblies. Associates Plumbing, Inc. performs all backflow services in-house and submits the test reports directly to the water utility service.

If you need to schedule backflow testing at your property or would like more information on our services, please contact us at (443) 917-2500.
