3. Make the Reverse Osmosis Waste Connections
The “RO” filter assembly requires a drain line connection to be
installed, which removes rejected water to the sewer. The drain
saddle connects the drain line from the dispenser to your drain pipe.
The drain saddle is designed to fit around a standard 1.5 in. OD (outer
diameter) drain pipe.
Always install the drain saddle before the P-trap and on a
straight vertical or horizontal section of the pipe.
To avoid clogging the drain line with debris, do not install the
drain saddle after the drain pipe meets a garbage disposal or
dishwasher drain.
To make the Reverse Osmosis (RO) drain connections:
A. Determine the location for your drain saddle (H) and then make a
mark on the drain pipe for the opening (1).
B. Use your drill and a 1/4 in. drill bit to drill a hole at the mark,
ensuring you only drill through one side of the drain pipe.
C. Find the half of the drain saddle (H) with the hole in the center,
remove the backing from the foam gasket, align the gasket with
the hole on the drain saddle (H), and stick the adhesive side of
the gasket to the drain saddle (H).
D. Position both halves of the drain saddle (H) on the drain pipe with
the saddle’s opening aligned over the drilled hole, and insert your
drill bit through the saddle (H) and drilled hole to ensure proper
alignment.
E. Secure both ends of the drain saddle (H) together using the bolts
and nuts, but do not over-tighten.
F. Connect the RO water outlet tube (I) to the drain saddle (H).
