drain
air
Some plumbing
codes
require
use of a drain
arr gap
be-
gap
tween
an undercounter
dishwasher
and the drain
system
of the house. The air gap
is usually
located
above
the sink
or on the top of the counter
near the dishwasher
to prevent
the possibility
of water
backing
up from the drain
into the
dishwasher
due to a plugged
drain.
The drain
air gap
is
NOT a part of the dishwasher
and
is NOT covered
by the
dishwasher
warranty
The drain
air gap
should
be kept
clean
to insure proper
draining
of the dishwasher.
