Step 2: Drain Saddle Installation
Important:
DO NOT REMOVE the black drain tubing from the RO system system! If you
need to extend the drain tubing please use a union connector to connect
additional length of tubing.
Note:
To avoid possible drainage noise, mount drain line as low as possible on the
vertical tailpiece, or on horizontal tailpiece.
There is constant water pressure “packed” inside the RO system which blocks the drain water from back-
ing-up into the system. So the drain water is “forced-drained”, not “gravity-drained”.
1.
See Fig. 6.
The drain saddle assembly should be installed above the trap and on the vertical or horizon-
tal tailpiece. To reduce the drainage noise, mount the drain line as low as possible above the trap, or on
the horizontal tailpiece.

SADDLE AT
EITHER
LOCATION
2. Select the location of the hole and drill a 1/4’’ hole through one side of the drain pipe then put the
self-adhesive black sponge around the hole location (See
Fig. 7A
and
7B
).
Next, align and install the drain saddle clip with the tubing connection port onto the black sponge.
This will cushion any gap between the saddle and the pipe. Make sure the hole on the sponge is
thoroughly punched out, and is aligned to the hole on the saddle to complete the installation (See
Fig. 8
)

Test for leaks after the system is completely installed: Close the Needle Valve (turn needle handle clock-
wise all the way in to close). Turn ON the cold water supply to the sink faucet. If the Needle Valve or the
Adapter leaks, check the connection and try applying more Teflon tape or tighten the brass nut some
more to stop the leak.
