Backflow FAQs

How often do I need to test my backflow? 

Backflow assemblies must be tested annually to make sure they are working properly. The City of Aumsville does not coordinate the testing of the assembly. If you are the property owner, you should contact a certified backflow assembly tester to schedule the testing. The tester should submit a copy of the test report to the Cross Connection Specialist.

Where can I find a certified backflow tester? 

The Oregon Health Authority keeps a list of currently certified backflow assembly testers. You can access the list from their website. 

When should I get my backflow tested? 

Your backflow assembly must be tested at least once a year. The City of Aumsville will send the property owner a reminder of backflow assembly testing requirements. The backflow assembly must be tested within 30 days of receipt of this reminder. If we have not received a test report within the first 30 days, a second and, if needed, a final notification of the annual backflow testing requirement will be sent to the property owner.

Why must I have a backflow assembly? 

A backflow assembly prevents the backflow, or the undesirable flow of non-potable water or other substance back into the drinking water system through a cross connection. A cross connection is any temporary or permanent condition between the potable drinking water system and any source or system containing non-potable water or any other substance.

Certain conditions or hazards require the installation and annual testing of a backflow assembly. For a residential customer, hazards are most commonly underground irrigation systems.
