Shut Off the Water
Check for Leaks
Locate the water shut-off valve for the cold water feed line you choose to use for the supply. Accidentally hooking up the
system to the hot supply line will permanently damage the membrane (See Conditions for operation). To assure you are using
the cold water line, turn on both the hot and cold faucet. After the water is warm to the touch, feel the pipes under the sink. It
will be easy to identify the hot and cold pipes.
Close the cold water valve. Turn on the cold water faucet only to assure that the
line is completely shut off and the line is drained. If no shut off valve is located
under the sink, turn off the main supply at the entry to the house.
Place the clamp over the cold water supply line. The aluminum spacer has two
sides to adapt to different tubing sizes. Use the small radius for 3/8” tubing and
the large radius through 5/8”. Use the clamp screw to attach the saddle to the
copper pipe. Tighten the brass clamp screw with a 7/16” wrench.
Do not crush the tubing
Do not over tighten the clamp. The clamp should be secure and resist a slight
twisting force.
Turn the saddle tapping valve clockwise until the needle fully pierces the tubing
and the valve seats. For maximum flow, back the handle out all the way. Adjust as
required.
Turn on the cold water supply. Check the saddle tapping valve for leaks. Allow the water to run for a minute to clear any
possible debris from the saddle tapping device.
If flow from the faucet is reduced, remove, clean, and reinstall the faucet aerator.
Select a location for the drain hole based on the design of the
plumbing. Position the drain outlet saddle on the drain pipe. Allow
adequate space for drilling. Tighten the bolts evenly on both sides.
Avoid overtightening.
Using the opening in the drain outlet saddle as a guide, drill a
1/4” hole in the drain pipe. Clean debris from the saddle and
threads.
NOTE: Some areas require the use of an air gap faucet.
Check your local plumbing code to assure compliance.
Locate the drain connection away from the garbage
disposal to prevent potential contamination and system
fouling.
