What instrument is used to test Double Check Valve Assemblies in the field?

Barometer
Differential Pressure Gauge
Flow Meter
Hydrostatic Tester

The correct answer is: Differential Pressure Gauge

The instrument used to test Double Check Valve Assemblies in the field is the Differential Pressure Gauge. This tool is specifically designed to measure the pressure difference across the two check valves within the assembly. In the context of cross-connection control and water safety, it is crucial to ensure that the valves are functioning correctly to prevent any backflow that could contaminate the drinking water supply. Double Check Valve Assemblies are commonly used as backflow prevention devices, and their proper operation is essential. The Differential Pressure Gauge helps to ascertain that the check valves are closing properly and that there is no unintended pressure loss, which could indicate a malfunction or leakage. By monitoring the pressure differential, technicians can effectively determine whether the assembly is working as intended and ensure compliance with safety standards.
