How To Find A Tester
Currently, the Backflow Prevention Program (BPP) cannot recommend testers nor does the city keep a list of testers. If you are in need of a tester, you can find one by:
- Consulting With Your Current Plumber or Contractor - these professions usually hold their own certification or know someone who can test your assembly. Whomever you select to test your BFPA must be certified to do so. Testers must hold a current certification from either The American Backflow Prevention Association, or The American Society of Sanitary Engineers.
- Checking Your Assembly - Generally your existing BFPA has been tested before and should have a tag from the previous tester that shows the tester's or testing company phone number.
- Visiting the Colorado Division of Fire Prevention & Control website if you're looking for someone who can also test assemblies on fire lines. Click on "Fire Suppression Systems" and then on "Backflow Contractors."
How Assemblies Are Tested
BFPAs are tested by certified testers who use gauges to either add or relieve pressure to determine if the internal parts are working properly. This information is recorded on a BFPA test report. These test reports are sent (generally by the tester) to the city's BPP.
What Test Form Should Be Used?
The City of Boulder's BPP uses a Universal Test Form created, used and accepted by backflow programs across Colorado. Incomplete or incorrectly filled out forms will be returned to the tester.
When the BFPA passes the test, the tester must submit a copy to the BPP within 10 days from the test date. This information will be recorded by the program and testing will not be required until the following year.
BFPAs that fail a test must be repaired and/or replaced immediately. The BPP must be verbally notified the same day and the failing test should be submitted within three days. If the repair or replacement cannot be made immediately, the BPP must be notified and a compliance plan must be established.
As a failed BFPA test represents a direct cross-connection, failure to repair/replace and test an assembly can result in suspension of water service if the BPP determines that the cross-connection represents an immediate risk to public health.
Keeping Copies Of Test Reports:
Article 12 of the Colorado Primary Drinking Water Regulation states that BFPA test reports should be kept for three years.
Tester Certification Information:
Backflow Prevention Assembly Testers must be certified by one of two National Certifying Agencies:
- The American Backflow Prevention Association (ABPA)
- The American Society of Sanitary Engineers (ASSE)
Both organizations re-test every three years and anyone testing a BFPA must have a current certification on the date of the test.
