3. Self Piercing Valve and Tubing Installation
The self-piercing valve, which is supplied, is designed
for use with 3/8” to 1/2” OD copper or chrome plated
copper tubing, CPVC, & flexible gray riser tubes at least
3/8” in size. It should not be used on ribbed, corrugated,
reinforced plastic or steel braided tubing. Ask your local
dealer what alternatives can be used in place of the self-
piercing valve if one cannot be used under your sink.
Fig. 2
Installation procedures using copper tubing/pipe or
tubing, CPVC, and gray flexible riser tubes:
(See Figure 2)
1. Turn off cold-water valve from under the sink or main
water line valve for whole house.
2. Before installing saddle valve, make sure piercing
lance does not protrude beyond rubber gasket.
3. Assemble saddle valve on tube/pipe (As shown in
Figure 3)
4. Turn handle clockwise until it stops to pierce tube/pipe,
(Valve is closed in this position)
5. Turn on water supply to pressure cold water line.
6.
Snug nut/seal with wrench around valve stem.
7.
Connect tubing to feed water valve using brass
compression nut, stiffener insert and plastic sleeve.
8. To open valve, turn handle counterclockwise.
Saddle valve installations with other metal pipe:
1. Turn off cold water supply.
2. Drill 3/16” hole at desired location.
3. Make sure piercing lance does not protrude beyond
rubber gasket.
4. Assemble saddle valve on pipe, aligning with hole.
5. Turn saddle valve handle clockwise to close valve.
6.
Tighten nut/seal around valve stem with wrench.
7.
Connect tubing to feed water valve using brass
compression nut, stiffener insert and plastic sleeve.
8. Turn on cold water supply.
9.
To open valve, turn handle counterclockwise.
4. Drain Saddle Valve Installation
(See Figure 3)
A Drain Saddle is used to make a wastewater connection
with the drain under the sink, which is designed to fit
around a standard 1-1/2” OD drainpipe. The drain saddle
valve should always be installed before (above) the p-trap
and on a vertical or horizontal drain. Do not install the drain
saddle near a garbage disposal to avoid clogging the drain
line with debris.
Fig. 3
Procedures:
1. Position the drain saddle valve at selected location and
mark for the opening.
2. Drill 1/4” hole at mark through one side of pipe.
3. Remove backing from gasket and place adhesive side
to the fitting half of drain clamp around hole.
4. Position both halves of drain saddle on drain pipe so
the opening aligns with drilled hole. Use a small drill bit
to verify that drain clamp is properly aligned.
5. Secure drain saddle clamp on valve with bolts and nuts
provided. (Do not over tighten and make sure there is
equal space between saddle halves on each side)
5. Initial tubing connections
For convenience on under sink installations it may be
advisable to complete under sink tubing connections at this
time.
6. RO Component Installation
Install RO membrane O-ring end first, carbon prefilter(s)
and sediment pre filter in vertical mounted housings. Be
sure RO Membrane is pushed into Membrane housing
as far as it will go. It is recommended that filters and
membranes be handled with clean or gloved hands.
7. RO Unit Installation
The RO unit is normally mounted to the right or left sink
