What is the minimum height a Double Check Back-flow assembly should be installed above the ground?

The correct installation height for a Double Check Back-flow assembly is specified to be at least 12 inches above the ground. This minimum height is crucial for ensuring proper drainage and maintenance of the device, as well as preventing the potential for floodwaters to contaminate the water supply. Installing the assembly at this height helps to minimize the risk of debris and sediment accumulation, which could impede its functionality. Furthermore, this elevation is part of standardized guidelines for backflow prevention devices to enhance the safety and reliability of the water distribution system. Ensuring that all backflow prevention assemblies are installed at the proper height is a critical part of maintaining potable water quality and protecting the public water supply.
