The 3-compartment sink must drain to a floor sink via an indirect connection with a one inch air gap above the top of the sink. 3-Compartment sinks must be equipped with an automatic shut-off valve that will automatically shut off the flow of water from the 3 compartment sink when the water level in the main water supply tank drops below a specified level.
The valve must have a minimum flow rate of 1.5 gallons per minute (gpm) and a maximum discharge pressure of 5 psi (7.2 kPa) at a water temperature of 40°F (4°C). The water must not be allowed to flow through the valve during the time that it is in use.
