To become an approved tester for the City of Concord's Backflow Program, you must register HERE and be approved by the City's Backflow Department. Once approved, you will automatically be added to the public facing City’s Approved Backflow Testers List. This tester list will be updated on February 3 with all approved testers.
Registration Instructions can be found here. Please be aware you will need to include information and images of your Tester Certification and your Test Kit and Calibration.
Each backflow prevention assembly that is required must function properly at time of installment. Each customer will be required to test, maintain, and repair each assembly required which is a part of the customer's private water system. A certified backflow prevention technician may only conduct such test. Testing shall be done immediately following installation of any backflow prevention assembly and on an annual or semiannual basis depending the degree of hazard. We will not accept backflow test reports by fax, mail, or hand delivered copies after this date.
