INSTALL DRAIN ADAPTER (Cont.)
2. Using the hole through the drain fitting as a guide,
mark the pipe where a 3/8” hole will be drilled,
and remove the drain adapter from the pipe.
NOTE:
Do not drill through the drain adapter’s Q.C.
fitting, as this could damage the o-ring.
3. Drill a 3/8” dia. hole in the pipe and remove flash.
4. Clean the sink tailpiece to assure a leak-tight fit.
5. Place the halves of the drain fitting back onto
the sink drain pipe. Use a pencil or similar
pointed object to align the Q.C. fitting so that it
is centered on the hole you drilled.
6. Assemble the nuts and screws, as shown in the
illustration above, and tighten both sides equally
to secure the drain adapter halves onto the pipe.
Do not overtighten.
7. Do not connect black tubing to the Q.C. fitting at
this time. It is done after the RO faucet is installed.

INTRODUCTION
A suitable drain point is needed for the drain water
from the Reverse Osmosis system. Options are:
• Install the included Drain Adapter
As shown below, install the included drain
adapter onto the sink’s drain pipe above the P-
trap. This is normally used for under sink
installations.
NOTE:
Do not install drain adapter on a line
coming from a garbage disposal.
• Use another existing drain in the home
Run the drain tube from the RO system directly
to an open drain. This is often used for remote
location installations.
NOTE:
An incorrectly connected drain point can
cause water to leak from the faucet’s air gap.
NOTE:
Local code may restrict the type of drain
installation to use. Either drain installation
type, if permitted by code, may be used in
under sink or remote location installations.
Consult a plumber if you are not familiar
with plumbing procedures.
INSTALL DRAIN ADAPTER
The drain adapter included with the RO system is
designed to fit around a standard 1-1/2” O.D. drain
pipe. In the following procedure, install the drain
adapter above (upstream of) the P-trap. Be sure
to comply with local plumbing codes.
NOTE:
Before starting this procedure, inspect the
drain pipe under the sink for corrosion, and replace
if necessary, before continuing with installation.
1. Test fit the two halves of the drain adapter onto
the sink drain pipe, about 6 inches above the P-
trap. Make sure that the quick connect (Q.C.)
fitting is toward the direction of the RO faucet.
NOTE:
Locate so that the drain tubing from the
Reverse Osmosis faucet will run straight to
the adapter, with no dips, loops, or kinks.
