Certified backflow prevention assembly tester registration fee: Annual registration fee of $75 for TCEQ approved testers shall be a nonrefundable fee to show proof of their current TCEQ license and testing equipment in accordance with current TCEQ regulations. Register now using the Tester Registration Form (PDF). All backflow assembly test reports for existing and replacement backflow devices must be submitted via the BSI Online Backflow Tracking System.

All testing companies are required to submit test reports within 48 hours of test date. Failure to do so will result in enforcement notification of the customer regarding the non-compliant status of their device. If not entered online, the ultimate escalation of enforcement is termination of customer’s water service.

Testers and testing companies are reminded to obtain the Customer Confirmation Number from your customer located at the top of the reminder or overdue letter received. This number is needed by the backflow tester in order to access records in the BSI Online System. Contact BSI if the number is lost or unknown.
