FiLTRATiON DRAIN CONNECTION (cont.)
PREFERREDINSTALLATION:
OPTION C--WET-VENTED P-TRAP
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 ROwater faucet. Locate the
Reverse Osmosis p-trap as high as possible (minimum
of 4" above horizontal).

A CAUTION: UsingOption D may result
in clogging under adverse conditions and requires
periodic inspection/cleaning
by the user.
DO NOT INSTALLTHE DRAIN LINE DOWNSTREAM OF
A DISPOSEROR 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
HAY 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.
