Installation Instructions
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

• 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 Ptrap.
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.

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 gray tubing to the Q.C. fitting at
this time. It is done after the RO faucet is installed.
