Certified Backflow Assembly Testers

Oregon Drinking Water Services (DWS) provides a public list of OHA-certified Backflow Assembly Testers. The list is voluntary and not all certified testers choose to be on the list. Select the county you want, and then you can sort by certification #, name of tester, employer, city, and state. If you are a certified specialist trying to verify a test report but don't see the tester on the list, email the DWS Cross Connection Program at cross.connection@state.or.us.

Only OHA-certified Testers are allowed to provide testing services in Oregon. Backflow Assembly Testers who provide their testing services for a fee are required to be licensed through the Construction Contractors Board (CCB) or the Landscape Contractors Board (LCB). Testers on the following list have provided information to DWS that they, or the company they work for, have either a CCB or LCB license; however, this information has not been verified. To verify licensing, you can look up CCB licenses or LCB licenses.
