The 3/8” drain tube must be as SHORT and STRAIGHT as possible from the RO
faucet to the drain saddle, making a downward slope from faucet to drain saddle to
allow for proper drainage. This is a gravity fed line and if there is any bend or dip
in the tube, the rinse water will not ow into the drain properly. Water may back
up and come out the air gap hole in the back of the faucet.
Locate the 3/8” drain tube attached to the RO faucet.
Measure the 3/8” drain tube from the RO faucet to the drain
saddle mounted on the drain pipe and make a straight cut
to the correct length per note above. Insert the open end
of the 3/8” black tube into the drain quick connect tting on
the drain saddle.
