Step 3 – install adapter Valve on Water Supply

Step 4 – Connect System Drain

Plumbing codes require that the drain from reverse osmosis drinking water systems be discharged through an air gap
siphon break. The faucet incorporates an air gap into its body. The discharge from the air gap must be connected to the
plumbing system for proper drainage. This connection can usually be made beneath the sink. Incorrect installation may
result in overflow of the air gap or excessive noise. If the concentrate water is discharged to an open drain, the air gap
may not be necessary.
For Air Gap installations select the 3/8” saddle, for Standard installations use the 1/4” saddle.
Connections to undersink plumbing can be made with a saddle clamp designed to accept the drain tubing from the
faucet. Drain Saddle Kit is supplied for 1-1/2” undersink drain plumbing (Figure 14).

Be sure to check and follow local

plumbing codes prior to installation.

Note: For installation in Massachusetts, Plumbing Code 248 CMR shall be adhered to. Consult your licensed plumber for

installation of this system. The use of saddle valves is not permitted in Massachusetts.

CautioN! If no shut off valve is installed under
sink, close main water valve. Do not install feed
water assembly on hot water line.

• Use small radius side for

3/8”copper pipe.

• Use large radius side for

1/2”copper pipe.

4. Tighten screw firmly so

saddle valve is held
securely in place. Do not
crush tube.

5. Connect feed tubing to

valve body using com-
pression fitting.

1. Locate shut off valves on water lines under sink. To iden-

tify hot & cold supply pipes, turn on both faucets and let
water run. Hot water pipe will be the warmer pipe. Turn
off cold water supply valve. Open sink faucet to drain
line. Some mixing faucets may require shutting off the hot
water valve as well.

7. Once all lines are connected to the RO system turn on

cold water supply. Turn Valve counter-clockwise and
check for any leaks. Run water from the faucet to clear
any debris caused by installation.

Note: if flow from sink faucet isreduced, clean faucet aerator.

6. Turn handle clockwise until

firmly seated and piercing
valve has extended fully.



CautioN! Do not turn valve handle before or
during installation of saddle valve. Be sure piercing
lance does not protrude prior to installing valve.
