Which standard is used for testing backflow prevention devices?

• A. ASSE 5013
• B. ASSE 5015
• C. CSA B64.10
• D. CSA B64.10.1

Answer: (A)

Backflow prevention devices are tested under a formal standard to ensure they reliably block reverse flow and protect potable water supplies. The standard used for testing these devices is ASSE 5013. It specifies the testing procedure, the sequence of tests, the pressure conditions to apply, acceptable leakage and performance criteria, and how results are documented. This creates a consistent, widely accepted framework so labs and inspectors can evaluate backflow assemblies—like reduced-pressure principle and double-check valves—across different manufacturers. Canadian standards such as CSA B64.10 and CSA B64.10.1 exist, but in many irrigation and water-supply contexts ASSE 5013 is the standard most commonly applied for testing backflow prevention devices.
