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. 


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 an additional 15 days. If after the 15 days a passing test report has not been received, a shut-off notice will be mailed allowing another 10 days in which 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 days the Compliance Department has not received a passing test, the Water Service will be shut-off due to non-compliance in which 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 reestablish 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 reestablished 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.
