INSTALL A REMOTE DRAIN POINT
AND AIR GAP (Remote Location)
Route the drain tubing to an existing drain in the house.
A floor drain, laundry tub, standpipe, sump, etc. are
suitable drain points. See Fig. 11. This type of drain is
the preferred over the p-trap drain adapter.
Always be sure to provide a 1-1/2” air gap between the
end of the hose and the drain point. This will prevent
water from backing up into the system.
NOTE: Check your local plumbing codes.
To install a remote drain point, complete the
following steps:
1. Locate the 1/4” red tubing on the Reverse Osmosis
filter assembly. See Fig. 10.
2. Determine if this length is long enough to reach the
drain point. Longer lengths of tubing (see parts list in
back of manual) may be needed.
3. If longer tubing is required, disconnect the 1/4” red
tubing and replace with an adequate length of tubing
to reach the drain point. Refer to Step F later in the
manual on how to disconnect and connect tubing.
NOTE: A flow control insert is located inside the
fitting that the drain tube connects to. See No. 12
on page 22. Leave this fitting in place.
4. Route the tubing to the drain point and secure at the
end with a bracket (not included). See Fig. 11.
Provide a 1-1/2” air gap between the end of the tube
and the drain. See Fig. 11.

IMPORTANT:
Allow adequate open

to avoid sharp bends
or kinks in the tubing.
