Backflow Tester List

State rules

South Dakota

South Dakota’s Department of Agriculture and Natural Resources says the state began primary enforcement of the Safe Drinking Water Act in 1983 and that the Drinking Water Program enforces the state drinking-water regulations for public water systems. The plumbing rules the state has adopted add a specific backflow sentence: a dual-check backflow preventer that conforms to ASSE 1024 must be installed on the building side immediately downstream of the water meter where the service enters the building. Adopted plumbing amendments also say copies of the initial test report for a testable backflow assembly, and copies of the annual test reports, are sent to the water supplier. Those amendments do not create a named state tester license.

The adopted plumbing packet says a backflow device must first meet the Uniform Plumbing Code approval section. The person in control must keep it in good working condition. If the administrative authority finds it ineffective, replacement is required. Each outlet is protected, preferably by an air gap. If an air gap is not possible, an accessible preventer goes on the discharge side of the manual control valve. Initial and annual test reports still go to the water supplier.

The same amendments say a testable assembly has properly located, resiliently seated test cocks and tightly closing, resiliently seated shutoff valves at each end. Initial and annual test reports for those assemblies go to the water supplier. Water-to-water heat exchangers that return water to the public system are not allowed unless the authority having jurisdiction approves them. ASSE 1024 in the meter rule is a device standard for the dual check. It is not a statement that an ASSE 5110 tester card is a South Dakota license. This research did not find a DANR page that issues a backflow-tester credential.

Ask the water supplier what annual report it expects and ask the plumbing authority who may sign it. The Drinking Water Program is the primacy agency for public water systems. The plumbing amendments are the device and report text used here. They do not name a tester license or a fee. ASSE 1024 remains the dual-check product standard at the meter, not a personal tester credential issued by the state.

What to do next

  1. Send the annual test report to the water supplier, because the plumbing amendment requires that copy.
  2. Ask the administrative authority who may perform the test; the state pages reviewed do not name a license.
  3. Do not read ASSE 1024 as a tester credential; the rule uses it as the dual-check device standard.
  4. Ask before connecting a heat exchanger that returns water to the public system.
