FILTRATION DRAIN CONNECTION
PREFERRED INSTALLATION:
OPTION A—BASEMENT ACCESS

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.
Check and comply with local plumbing codes as you plan.
CAUTION:
The options detailed below are the ONLY approved installation
configurations. Do not use any drain saddle device.
