A double check backflow prevention assembly contains which component?

A double check backflow prevention assembly is designed to protect a water supply from contamination due to backflow. The primary components of this assembly include two check valves, which prevent the reverse flow of water, as well as flow indicators that allow for the monitoring of the flow direction.

The inclusion of a flow meter or a flow indicator is crucial as it helps in detecting whether water is flowing in the intended direction, thereby providing an additional layer of safety against potential backflow incidents. The flow indicator ensures that anyone monitoring the system can quickly assess whether the water is flowing correctly, reinforcing the protective function of the assembly.

Flow meters and indicators are particularly relevant in double check assemblies since they facilitate routine checks and maintenance, ensuring that the assembly is functioning properly. This makes monitoring efficient and enhances the safety of the water supply.
