A certified tester uses specialized gauges to measure differential pressures across the assembly. RPZ devices are typically required for high-hazard connections.

Most jurisdictions in Hawaii require backflow testers to hold a current certification from an approved training program, typically involving classroom instruction, a hands-on practical exam, and continuing education credits. Some municipalities maintain their own approved-tester lists. Always verify certification before hiring.
