Copper alloy
A homogenous mixture of two or more metals in which copper
is the primary component, such as brass and bronze.
Critical level
An elevation (height) reference point that determines the

breaker is installed above the flood level rim of the fixture or
receptor served by the device.
Cross connection
Any physical connection or arrangement of pipes between two
otherwise separate building water supply pipes/ system.
Demand Recirculation Water System
