Backflow Testing Procedure
Backflow prevention devices are devices that are used in plumbing systems to protect potable water supplies from contamination or pollution due to back flow of dirty water or other materials. A properly installed, tested and maintained backflow device can reliably prevent the backflow of water into a potable water system. Many types of backflow devices also have test ports so that they can be tested and examined on a regular basis to evaluate whether they are functioning properly. Below are the steps in the backflow testing process.
Note: For a paper copy of the instructions, see the Backflow Testing Instructions.
1. Create the backflow devices during Backflow Inventory Maintenance and maintain the following fields:
2. Assign the Backflow devices to a service connection using the Create Service Connection Wizard.
3. Create
the Backflow Testing Workfile.
Tip: The backflow device's Last Test Date
and the Test Frequency or Test Month Calendar
work together to determine if the Backflow device is due to be tested.
4. Print and review the list of Backflow devices to be tested.
5. Print the Backflow Testing Notices and/or print the certified mailers for mailing to the appropriate customers.
6. After backflow tests have been performed, use Backflow Workfile Maintenance to update the backflow testing records with the test date and test status.
7. Run the Backflow Testing Post to update the backflow devices with the Test Date, Test Status and add testing detail to the history.
