FILTRATION DRAIN CONNECTION (cont.)
PREFERRED INSTALLATION:
INSTALLATION
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
drain line adapter to the p-trap and secure it with the
slip joint nut and washer as shown. The drain line MUST
be routed through the air gap provided in the RO water
faucet. Locate the Reverse Osmosis p-trap as high as
Reverse

SECONDARY INSTALLATION:
INSTALLATION
CAUTION:
in clogging under adverse conditions and requires
periodic inspection/cleaning by the user.
DO NOT INSTALL THE DRAIN LINE DOWNSTREAM
OF A DISPOSER OR IN A HORIZONTAL PIPE. Install
the drain line adapter under the sink as shown (parts
included). The baffle tee shown must be installed 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. The drain line adapter should be aligned
vertically so that the hose connection points upward
(the hose connection should never be allowed to drop
below 45° from this vertical position). This installation
MAY result in a slight drain noise in the sink drain when
the Reverse Osmosis system is regenerating. If this
happens, simply place the sink drain stoppers in the
strainer to suppress it.
