What Tucson Water Customers Need to Know
Tucson Water requires applicable backflow prevention assemblies to be tested annually. The customer is responsible for arranging the test and making sure the requirement is completed by the date on the notice. Tucson Water says its annual notification provides a 45-day compliance window.
Do not wait until the final few days. Tester availability, equipment access, a failed assembly, repairs, or permit questions can all add time. The exact due date on your notice controls.
Use a Tucson Water-Approved Certified Tester
Tucson Water requires customers to use an approved certified tester. Use the utility’s current approved-tester information rather than relying only on a general web search or an old referral. Before scheduling, confirm that the tester is eligible for Tucson Water work and will submit the result through Tucson Water’s required online process.
Check the official Tucson Water tester information.
The 45-Day Compliance Window
The annual notice identifies the assembly and its compliance deadline. Tucson Water describes the standard notice period as 45 days. A practical timeline is:
- Review the notice immediately. Confirm the service address, assembly information, and due date.
- Contact an approved tester early. Leave time for access problems or corrective work.
- Complete the test. Ask the tester when the result will be filed.
- Follow up on a failure promptly. Repair or replacement and a passing retest may be needed before the compliance date.
- Keep your records. Save the notice, invoice, test date, and any confirmation supplied by the tester.
How Test Results Are Reported
Tucson Water states that the approved tester submits test data directly to the utility online within five days after completing the test. Customers should not assume that paying an invoice automatically confirms compliance; ask the tester whether the result was submitted and retain the test details.
A failing result should still be reported. If repair or replacement is required, the corrective work and passing result must be handled within the applicable deadline, and the tester submits the follow-up result through the same Tucson Water process.
What Happens After a Failed Test?
A failed assembly is not automatically a full replacement. The cause may be debris, worn internal components, damaged test cocks, leaking shutoff valves, corrosion, freeze damage, or another mechanical issue. The appropriate next step depends on the assembly type, condition, installation, and current Tucson Water requirements.
After repair or maintenance, Tucson Water requires a certified tester to retest the assembly and submit the new result. Schedule follow-up quickly so there is time to complete the work before the notice deadline.
Installation and Replacement Permits
Tucson Water indicates that permits are required to install or replace backflow prevention assemblies. Before authorizing replacement, confirm the current permit, assembly, location, and inspection requirements with Tucson Water. This is especially important when the existing device is relocated, resized, or changed to a different type.
What to Have Ready Before Scheduling
- The complete service address.
- A clear photo or copy of the Tucson Water notice.
- The compliance due date.
- The account, meter, or assembly number shown on the notice, if available.
- The assembly’s location and what it serves, such as irrigation, a commercial system, or another use.
- Gate codes, lockbox instructions, or an on-site contact.
- Details about leaks, previous failures, buried boxes, broken valves, or recent repairs.
Does Tucson Water Serve This Address?
A Tucson mailing address does not always identify the water provider or backflow program. Properties near jurisdiction and utility boundaries may follow different tester lists, forms, and reporting systems. Check the provider shown on the water bill and on the testing notice before scheduling.
