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 Valve Kit
White
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
Use Teflon tape to wrap the threads of the adapter – approximately 3 wraps.
If your cold water feed line is ½”, use the
⅜
” to ½” adapters provided.
o
If your feed line is
⅜
”, you do not need these adapters.
f
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.
