PREFERRED INSTALLATION:
OPTION A—BASEMENT ACCESS
INSTALLATION
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 air gap installation is left to
the discretion of the installer. The drain line
may also be routed to a floor drain or washtub,
provided that the air gap is maintained. Special
air gap fittings are available to connect the drain
line to the top of the standpipe.

p-trap that has its own vent/stack. Attach the
