Backflow Tester List

State rules

Alaska

Alaska’s drinking-water rule, 18 AAC 80, is administered by the Department of Environmental Conservation. Section 18 AAC 80.025 prohibits a person from constructing, installing, or using a cross-connection in a public water system, and from connecting a water system that contains a cross-connection to a public water system. If the department determines a facility could contaminate the system through backflow, the public-water-system owner must install, maintain, and test a backflow prevention assembly on the service line and at other locations in that facility. The owner may delegate that work to the facility operator, but the owner stays responsible. The section does not create a state tester license.

Who may test an assembly
18 AAC 80.025 requires the public-water-system owner to install, maintain, and test the assembly, and allows delegation to the facility operator. It does not license testers.

The assembly required by 18 AAC 80.025 must conform to ANSI/AWWA Standard C510-97, Double Check Valve Backflow Prevention Assembly, or ANSI/AWWA Standard C511-97, Reduced-Pressure Principle Backflow Prevention Assembly, as those standards are adopted by reference in 18 AAC 80.010. The rule uses the word test, but it does not name a state certificate, and it does not say DEC accepts ASSE or ABPA tester cards. Delegation to the operator of the facility that poses the risk does not relieve the public-water-system owner of the duty to install, maintain, and test the assembly.

DEC’s sanitary-survey preparation page treats a backflow prevention assembly that is not tested annually as an example of inadequate routine maintenance. It also lists a defective cross-connection device, or no device, as a common deficiency, with a hose bibb lacking a built-in or screw-on device as an example. An arrangement that poses a cross-connection threat, such as a water-softener drain plumbed directly into a sewer drain, is another example on that page. Those survey notes show how inspectors look at protection in the field.

A violation of the cross-connection prohibition in 18 AAC 80.025(a), or a failure to install, maintain, or test a backflow prevention assembly as required under 18 AAC 80.025(b), is listed among violations that can draw five points in the chapter’s penalty-point provisions. That is an enforcement signal, not a tester-credential rule. People who test in Alaska should ask the public water system what proof of competence it will accept, because the state rule places the testing duty on the system owner and does not publish a state roster of testers.

Key facts for Alaska

What to do next

  1. Ask the public water system, not a private trainer’s brochure, what proof of testing it will accept.
  2. Remember the system owner stays responsible even if the facility operator does the test.
  3. Check hose bibbs and softener drains before a sanitary survey; DEC lists those as common deficiencies.
  4. Do not assume an out-of-state tester card is enough; 18 AAC 80.025 does not name one.
