2. I received a notice in the mail, what do I do?

1. Hire a Certified Backflow Tester.

3. Check your test report status using your CCN at BSI Online Tracking Customer Portal.

Tester will need to:

1. Preform the required test.

3. Why do I need to have my assembly tested?

Backflow prevention assemblies are mechanical devices, containing springs and other moving parts that are subject to wearing down and/or breaking. Routine maintenance and testing is necessary to ensure the device is working properly. Washington State law requires assemblies be tested annually. The District has compliance months January 1^st through May 31^st.  

4. What if my assembly fails the test?

If you had your assembly tested and it did not pass, you will need to have the assembly repaired or replaced and submit a passing test report.

5. What if I don’t get my assembly tested?

If the assembly is not tested within the allotted time frame (January 1^st through May 31^st annually), charges will be added to your account and the service will be terminated. For more information see Notification Procedures.

6. What do I do with the test results?

Customers should keep a copy for their records, and to ensure that the backflow technician has submitted the report to BSI Online.  Using your customer confirmation number (CCN) located on the notice, you will be able to verify the test has been submitted through the BSI Online Customer Portal.

7. I have my assembly tested every year, but my neighbor says they have never heard of the testing requirements. Why is that?

There may be several reasons why your neighbor has not received any notifications from Cross Valley, the most likely being that we don’t know about the installation. Many times customers make modifications to their private water system and do not inform the district. Have them give us a call (360) 668-6766, we can check the account.

8. I am not using my irrigation system anymore. Do I still need to test the backflow assembly?

As long as the irrigation system is physically connected to the water system, the assembly must be tested. Cross Valley can suspend the testing requirement if the customer provides a physical disconnect between the irrigation system and the public water system by removing the assembly and/or cutting and capping the water supply line. This has to be inspected by Cross Valley staff. Please contact the office at (360)668-6766 with additional questions or to schedule an inspection.
