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 flow 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.
Slip the 3/8” tube open end through the black compression
nut. Insert the 3/8” tube into the opening in the drain saddle and
hand tighten the black nut, add 1/4 turn with a wrench.

Locate the green 1/4” tube and plastic tube insert in the parts bag.
Push the entire plastic insert into green tube. To connect the tube to
the elbow fitting on the sediment pre-filter housing lid, push the 1/4”
green tube through the white compression nut. Hand tighten the nut
to fitting and add 1/4 turn with a wrench.
(See Picture to the right)
Insert the other open end of the green 1/4” tube into the open 1/4”
quick connect fitting on the plastic adapt-a-valve making sure the
tube is pushed in all the way passed the o-ring to the tube stop.
(Refer to quick connect instructions on page 7)
Step 15
Remove the white 1/4” x 1/4” plastic union and two plastic tube
inserts from the parts bag. Locate the 1/4” drain tube from the RO
faucet and the 1/4” red drain tube from the membrane housing.
Remove the two white compression nuts from the union and push
them onto the tubes. Next, push the entire plastic tube insert into
each of the tube ends. Insert the assembled drain tube from RO
faucet into one end of the white plastic union and the red drain
tube from membrane housing into the other end threading the
compression nuts on to the union. Use a 5/8” wrench to tighten
both of the white plastic nuts securely.
