Backflow Services Available in Oro Valley

Certified Work on Backflow Assemblies

Oro Valley Water Utility requires contractors performing work on backflow prevention assemblies to be certified. The requirement applies to testing, repairs, installations, retrofits, and replacements—not only the annual test.

If you received a due notice, include the service address and any assembly information shown on the notice when preparing for provider contact. This helps identify the device and the work that may be needed before the appointment is scheduled.

Residential and Irrigation Backflow Service

Backflow can occur when pressure changes cause water to move in the opposite direction from its intended flow. An approved, working assembly helps prevent irrigation water or other potential contaminants from entering the drinking-water system.

Residential property information may involve irrigation connections, pools, private plumbing systems, or other cross-connections that require service protection. If you are unsure what type of assembly is installed, send a photo for provider review when possible.
