Installation Instructions
FILTRATION DRAIN CONNECTION INSTALLATION
Check and comply with all state and local plumbing codes as you plan.
CAUTION: The options detailed in this section are the ONLY approved installation configurations.
Do not use any drain saddle device.
OPTION A: BASEMENT ACCESS
INSTALLATION
Route the drain line (1/4″ black line) DIRECTLY from
the Reverse Osmosis system to a standpipe in the
basement, bypassing the air gap provided in the
faucet. The drain line may also be routed in the
basement to a floor drain or washtub, provided
that the air gap in the basement is maintained.
Avoid dips, loops or low spots in the drain line.
The basement air gap and drain installation
configuration must conform to all local codes.
Special air gap fittings are available from your
local hardware store to connect the drain line
to the top of the standpipe.

OPTION B: DRAIN LINE ADAPTER
INSTALLATION
CAUTION!
DO NOT INSTALL DRAIN LINE ADAPTER
DOWNSTREAM FROM DISPOSER.
Install the provided drain line adapter under the sink
as shown. The baffle-tee provided must be in place
(purchase and install if necessary) to prevent a clog
in the Reverse Osmosis drain line. Route the drain line
(3/8″ black) from the faucet air gap to the drain line
adapter, ensuring that there are no dips, loops or low
spots in the line that could result in a clogged
drain line.
The tubing must be cut to length to provide
a straight routing from the faucet to the drain.
Drain noise in the sink drain is normal when the
Reverse Osmosis system is operating.
FAUCET DRAIN TUBING AND WATER SUPPLY TUBING
If OPTION A: BASEMENT ACCESS INSTALLATION (see Filtration Drain Connection Installation section, above) was
used, go to Step 2.
If OPTION B: DRAIN LINE ADAPTER
INSTALLATION was used, connect the faucet
drain tubing by running the 3/8″ black tubing
from the 3/8″ faucet barb to the drain fitting
(installed in Filtration Drain Connection
Installation section, above). Keep this tubing run
as short and straight as possible, without loops,
dips or low spots. Cut the tubing as needed and
insert into the drain fitting.
