FILTRATION DRAIN CONNECTION

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.
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.
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.
