Installation, Operation and Maintenance Manual
6. Install the Drain Connection (Figure 5)
For basement installations, the drain saddle is generally not used. Instead, the RO reject line is routed so
that it drains into a laundry sink, fl oor drain or standpipe through an approved air gap.
Under counter Installations:
The drain saddle assembly is designed to fi t around a standard 1 1/2” O.D. drain pipe. For smaller (lavatory
type) or larger (ABS pipe) drains, consult your Aqua-Pure
® distributor.
NOTE: The drain saddle should always be installed above (before) the trap and on the vertical or horizontal
tailpiece. Never install the drain saddle close to the outlet of a garbage disposal or dishwashing drain be-
cause plugging of the RO drain line may occur.
A) Remove backing on foam seal and place over hole on threaded half of the drain saddle. Place drain
saddle at the selected location and mark the pipe through the threaded opening.
B) Drill a 1/4” hole at the marked spot through one side of drain tailpiece.
C) Position both halves of drain saddle on drain pipe so the threaded opening lines up with the hole in the
drain pipe.
D) Use bolts and nuts to clamp drain saddle onto drain pipe. Do not overtighten and make sure that there
is equal space between saddle halves on each side. CAUTION: Overtightening could result in damage
to the drain line, which may lead to fl uid leaking.
E) Wrap PTFE tap on thread of drain saddle elbow and tighten into drain saddle. Orient elbow in the direc-
tion of RO faucet location.
7. Install the Faucet
NOTE: Under counter installations require a faucet with faucet air gap module. See Figures 1 and 2.
A wide variety of RO faucet mounting situations can be encountered, the most common being stainless
steel and ceramic on metal sinks.
The faucet should be positioned so that it empties into the sink and the spout swivels freely for convenience.
If the sink already has a hole provided that can accommodate the RO faucet, then no drilling is required and
you can proceed to the section on mounting the faucet.
NOTE: Sprayers can be disconnected to provide a suitable hole for the RO faucet. A pipe cap or plug will
be required to seal the sprayer connection on the existing faucet.

• Before starting the under counter installation procedure, inspect the condition of the drain piping, especially in
older homes where the traps and tailpieces can be deceptively thin and frail.
• Some state and local plumbing codes may prohibit the use of saddle-type valves and/or drain connections. See
page 2 for list of states. Optional feed valve assemblies can be purchased.
