FILTRATION DRAIN CONNECTION INSTALLATIONS
Check and comply with all state and local plumbing codes as you plan.
CAUTION: The options detailed below are the ONLY approved installation
configurations. Do not use any drain saddle device.
NOTE:
Failure to follow these Installation Instructions will void the Warranty, and the
Installer will be responsible for any service, repair, or damages caused thereby.
PREFERRED INSTALLATION OPTIONS
(Options A, B and C)
OPTION A.
BASEMENT ACCESS INSTALLATION (FIG. 3A)
Route the drain line
DIRECTLY
from the Reverse Osmosis system to a standpipe in
the basement, bypassing the air gap provided in the faucet. The drain line may also
be routed in the basement to a floor drain or washtub, provided that the air gap in the
basement is maintained.
Avoid dips, loops or low spots in the drain line.
The basement
air gap and drain installation configuration must conform to all local codes. Special air
gap fittings are available to connect the drain line to the top of the standpipe.
OPTION B.
SEPARATE VENT INSTALLATION—2 P-TRAP (DRY-VENTED) (FIG. 3B)
Install a separate dry-vented p-trap under the sink to be used exclusively for the Reverse
Osmosis drain line. A dry-vented p-trap is a p-trap that has its own vent/stack. Attach
the provided drain line adapter to the p-trap and secure it with the slip joint nut and
washer as shown. Route the drain line from the air gap to the drain line adapter
ensuring that there are
no dips, loops or low spots in the line, which could result in a
clogged drain line.
The drain line adapter should be aligned vertically such that the
hose connection points in a direction 45° of vertical. (See Fig. 3E.) The drain line
MUST
be routed through the air gap provided in the RO water faucet.
OPTION C.
SHARED VENT INSTALLATION— 2 P-TRAP (WET-VENTED) (FIG. 3C)
Install a p-trap under the sink to be used exclusively for the Reverse Osmosis drain line.
A wet-vented p-trap is a p-trap that shares a common vent/stack. Attach the provided
drain line adapter to the p-trap and secure it with the slip joint nut and washer as
shown. Route the drain line from the air gap to the drain line adapter ensuring that
there are
no dips, loops or low spots in the line, which could result in a clogged drain
line.
The drain line adapter should be aligned vertically such that the hose connection
points in a direction 45° of vertical. (See Fig. 3E.) The drain line
MUST
be routed
through the air gap provided in the RO water faucet. Locate the p-trap as high as
possible (minimum of 4
″
above horizontal pipe from second sink or disposer).
SECONDARY RECOMMENDATION
(Use only if option A, B or C is not possible.)
OPTION D.
DRAIN LINE ADAPTER INSTALLATION (FIG. 3D)
DO NOT install the drain line DOWNSTREAM OF A DISPOSAL or in a
HORIZONTAL PIPE.
Install the provided drain line adapter under the sink as
shown. The baffle-tee or y-connector shown
MUST
be in place (purchase and install
if necessary) to prevent a clog in the Reverse Osmosis drain line. Route the drain line
from the air gap to the drain line adapter ensuring that there are
no dips, loops or low
spots in the line, which could result in a clogged drain line.
The drain line adapter
should be aligned vertically so that the hose connection points in a direction 45° off
vertical. (See Fig. 3E.) This installation
MAY
result in a slight drain noise in the sink
drain when the Reverse Osmosis system is operating. Rotate the Drain Line adapter tee
assembly slowly until noise is minimized. Generally, 180° opposite the existing
horizontal pipe/baffle-tee is a good orientation.
