Step 4 – System Feed Line Installation
For this step you will need:

½” and 7
/
16
” open-end wrenches (or two adjustable wrenches)

Teflon Tape

Feed Adapter (in the size that matches your line) & Ball Valve Kit

Tubing
Locate and Turn Off the Cold Water Supply

Locate the valve in the cold water feed line you use for the supply.
Notice:
Accidentally hooking up the system to the hot water 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 sink faucet to drain water and relieve pressure from the lines.

If no shut off valve is located under the sink, or if water continues to come out of the faucet, turn off the
main supply at the entry to the house, then turn on the sink faucet to drain water and relieve pressure from
the lines.
Assemble the Ball Valve & Adapter Kit

Identify your line size and use the appropriate feed adapter (3/8” or 1/2”). The
extra feed adapter is not needed.

Use Teflon tape to wrap the threads of the ball valve – approximately 3 wraps.

Screw the ball valve into the adapter.
Install the Feed Adapter into the Cold Water Supply

Wrap the slip joint adapter with Teflon tape, approximately 3 wraps.

For Flex Line:
Loosen nut and separate cold water riser tube from faucet
shank. Gently bend riser rube so that slip joint fits onto faucet shank. Make
sure the flat washer is on top and the cone washer is on the bottom.
Reinstall riser tubes onto slip joint adapter and tighten.

For Solid Copper Riser Tube
: Same procedure as flex tubing except you
must cut a piece of the riser tube about ¾” to 1” so the slip joint adapter can
fit between faucet and riser tube.
Connect the Feed Line Tubing

Unscrew the nut from the ball valve. Slide the nut onto
the tubing, threaded sides facing the end of the tubing.
Feed the nipple on the ball valve into the tubing,
pushing the tubing until it slides over the lip. Slide the
nut to the threads on the ball valve, and tighten the nut
down over the tubing. Use a wrench to tighten ¼ turn
past finger-tight.

Connect the other end of the tubing to the feed port on the RO System.
