Backflow Testing

Welcome to the backflow assembly testing page. Here you will find everything you need to coordinate the testing of your backflow assembly and submit the results to Padre Dam.

Padre Dam is no longer accepting emailed, faxed or USPS mailed backflow test reports. Test reports will only be accepted through EcosConnect.

Padre Dam will send notifications through EcosConnect to customers with a backflow assembly 30 days prior to their testing due date. If you received a notice, you will need to do the following:

  • Have your backflow assembly tested by a licensed backflow tester. A list of Certified Backflow Testers is available below.
  • Provide your tester remote access code (Trac) number to your tester. The number is located on the upper right hand corner of the notice.
  • Once the test is complete, your tester will submit your results to Padre Dam through EcosConnect and will provide you with a copy.

Customers with a backflow assembly are required to test the assembly on an annual basis. The District will mail a first notice or a reminder notice with the test form 30 days prior to the required due date.

The customer is responsible for contacting a testing company as well as any costs incurred from the test, including repairs and replacements. View a list of several licensed backflow testers (PDF). Customers may use any licensed backflow assembly tester, including a licensed tester that does not appear on this list.


If the Compliance Department at Padre Dam does not receive a passing test within the 30 day testing period, a final notice will be mailed allowing a 15-day extension. If a passing test report has not been received within 15 days of the final notice, a shut-off notice will be mailed allowing another 10 days, and the customer will incur a shut-off notice fee up to $28. The financial charge is to recoup the fees associated with the costs of delivering a Shut-Off Notice.

If after the 10-day extension the Compliance Department has not received a passing test, the water service will be shut-off due to non-compliance and the customer will incur a discontinuance fee of $60 added to their account. This fee covers the cost for District staff to shut-off and re-establish the water service. 

The Compliance Department will notify customers of the intended termination by courier service, door hanger, mail service or telephone 48 hours prior to the discontinuance of service. In the event of discontinuance, the water service will be re-established when the District receives a passing test report along with the discontinuance fee and the cost of service disconnection. These instructions have been prepared in accordance with the Districts Rule and Regulations (PDF) section 5.4.4.
