The drain piping can be routed to either a sink or a floor drain. If you route the
drain piping to a sink drain without using an air gap, the highest point of the drain
pipe must be above the highest water level in the sink, as shown below.
If you route the drain piping to a sink drain and use an air gap, refer to the figure
below for the placement of the air gap.
If an air gap is not
used, the drain line
must be elevated
above the water
level of the sink.
