Apply only to the type of backflow preventer identified as
dual-check-valve type for use on residential supply service or
individual outlets. They also cover vacuum breakers for use on
laboratory faucets in nominal pipe size of 3/8 only, although
inlet or outlet connections, or both, may be different when so
required for special installations
