Feed and Drain Connections
Feed Connection
1. Locate and turn off the angle stop valve on the cold water line feeding the sink. This valve will
usually be located under the sink on the pipe coming out of the wall.
2. When the angle stop valve is closed, relieve pressure in the line by momentarily opening the
cold water tap on the sink.
3. Disconnect the cold water faucet feed line at the angle stop valve.
4. Install the feed valve assembly into the angle stop. (Fig. 1)
5. Firmly press the green 1/4” tubing into the 1/4" connector on the feed valve assembly.
6. Connect the cold water faucet feed line into the feed valve assembly.
7. Make sure the small shut-off valve on the feed valve assembly is closed. Turn on the feed water
connection valve. Check for leaks.
7. Attach the small feed valve warning tag from the parts bag to the feed valve.
8. Attach the Shutoff Warning label to the system so that it is directly visible. Fill out the Date of
Installation label and attach to the side of the system.
Drain Connection
1. You will need an electric drill with a 3/8” bit and a screwdriver for this portion of the installa-
tion.
2. Obtain the drain saddle assembly, two 1 ½” bolts, two 3/8” hex nuts, and the small adhesive
foam pad from the small parts bag (Fig. 2).
3. Place the adhesive foam pad on the inside of the drain saddle front, aligning the holes.
4. Position the drain saddle on the drain pipe under the sink between the “P” trap and the sink
connection. Orient the drain saddle so that the opening is on the side of the drain pipe.
5. Using the bolts and hex nuts, hand tighten the saddle bracket evenly until the saddle grips the
pipe snugly. Use a Phillips screwdriver to fully tighten the bolts. Do not overtighten.
6. If necessary, remove the drain saddle connector nut from the opening of the drain saddle.
Using the connector opening in the side of the drain saddle as a guide, drill a 3/8" hole through
the wall of the drain pipe.
7. Extend the drain tubing from the RO dispensing faucet to the drain saddle and measure for
length. The tubing must be routed so that water can run downhill for the entire length of the
tubing from the faucet. Avoid low spots or loops. Cut the tubing shorter, if necessary.
8. Insert the drain tube from the R.O. dispensing faucet through the drain saddle connector nut.
Tighten the connector nut onto the drain saddle.
