Medford Water Commission (Medford Water): backflow testing rules
Serves Medford, OR. Every point below comes from Medford Water Commission (Medford Water)'s own pages, linked; check your notice for your own deadline.
Who must test
- Under state health regulations, backflow devices other than atmospheric vacuum breakers are tested after installation and every 12 months thereafter. Source.
- All irrigation systems connected to potable water lines must be equipped with a backflow device, and commercial and multi-family systems must install backflow protection at the service connection. Source.
- Single-family customers may arrange their own annual testing instead of allowing Commission representatives to test and repair the assembly. Installation and initial test remain the owner's responsibility. Source.
How the report is filed
- Any tester performing tests and maintenance must submit records to the Commission; when the Commission implements a backflow test and maintenance portal, testers will be required to enter results directly into it (regulations effective July 1, 2026). No portal vendor is named. Source.
Tester registration
- Medford Water points customers to the State of Oregon list of certified testers; no separate utility tester registration is stated. Source.
Fees
- The Residential Backflow Protection Program provides annual testing and routine repair for privately owned assemblies on single-family services; its costs are recovered in a base-level charge applied to all single-family residential water services. No amount is stated. Source.
If a test is missed
- The Commission may immediately discontinue service to any premises where actual or potential cross-connections exist; compliance with cross-connection control rules is mandatory. Source.
Program
- Medford Water's backflow page covers irrigation, pool, solar, fire sprinkler and well cross-connections and notes all Oregon utilities must run backflow prevention programs. Source.

Finding a tester Medford Water Commission accepts
We found no tester list on Medford Water Commission's own pages. Use a state certified tester, and check your notice in case it names the testers or the portal it accepts.
Before you book, ask the tester:
- Are you registered with Medford Water Commission?
- Will you send the test report to the utility for me, and how?
- When is my report due? The date is on your notice; the tester needs time to test, repair if needed and file.
