Step B - Install RO Drain Under Sink
INTRODUCTION
A suitable drain point is needed for the drain water from the
Reverse Osmosis filter. You have two options:
• Install the Drain Adapter included with your unit
As shown in Figures 6 and 7, the drain adapter is installed onto
your sink's drain pipe above the P-trap. This is normally used
for under sink installations.
• Use another existing drain in your home
As shown in Figures 8 and 9, the drain tube from the RO filter
runs directly to an open drain. This is often used for remote
location installations.
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
(Under sink Installation)
The drain adapter included with your RO system is designed
to fit around a 1-1/2" (3.8 cm) O.D. drain pipe. In the following
procedure, you will install the drain adapter above (upstream
of) the P-trap. See Fig. 6. 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 (15 cm) above the Ptrap (See Fig.
7). Make sure that the Q.C. fitting is toward the direction of the
RO filter.
NOTE: Locate so that the drain tubing from the Reverse
Osmosis filter 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" (9.5 mm) hole will be drilled (See Fig. 7), 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" (9.5 mm) 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 Figure 7, and
tighten both sides equally to secure the drain adapter halves
onto the pipe. Do not overtighten.
