A cold water supply with water pressure of between 35 and
120 psi (241 and 827 kPa) is required to operate the water
dispenser and ice maker. If you have questions about your water
pressure, call a licensed, qualified plumber.
Reverse Osmosis Water Supply
IMPORTANT: The pressure of the water supply coming out of a
reverse osmosis system going to the water inlet valve of the
refrigerator needs to be between 35 and 120 psi (241 and
If a reverse osmosis water filtration system is connected to your
cold water supply, the water pressure to the reverse osmosis
system needs to be a minimum of 40 to 60 psi (276 to 414 kPa).
If the water pressure to the reverse osmosis system is less than
40 to 60 psi (276 to 414 kPa):
Check to see whether the sediment filter in the reverse
osmosis system is blocked. Replace the filter if necessary.
Allow the storage tank on the reverse osmosis system to refill
after heavy usage.
If your refrigerator has a water filter, it may further reduce the
water pressure when used in conjunction with a reverse
osmosis system. Remove the water filter. See "Water Filtration

Connect the Water Supply
Read all directions before you begin.
Plumbing shall be installed in accordance with the
International Plumbing Code and any local codes and
The gray water tubing on the back of the refrigerator (which is
used to connect to the household water line) is a PEX
(cross-linked polyethylene) tube. Copper and PEX tubing
connections from the household water line to the refrigerator
are acceptable, and will help avoid off-taste or odor in your ice
or water. Check for leaks.
If PEX tubing is used instead of copper, we recommend the
following Whirlpool Part Numbers:
W10505928RP (7 ft [2.14 m] jacketed PEX),
8212547RP (5 ft [1.52 m] PEX), or
W10267701RP (25 ft [7.62 m] PEX).
Install tubing only in areas where temperatures will remain
If you turn on the refrigerator before the water line is
connected, turn off the ice maker to avoid excessive noise or
damage to the water valve.
Connect to Water Line
1. Unplug refrigerator or disconnect power.
2. Turn OFF main water supply. Turn ON nearest faucet long
enough to clear line of water.
3. Find a ¹⁄₂" to 1¹⁄₄" (12.7 mm to 31.8 mm) vertical cold water
pipe near the refrigerator.
Make sure it is a cold water pipe.
Horizontal pipe will work, but the following procedure
must be followed: Drill on the top side of the pipe, not the
bottom. This will help keep water away from the drill. This
also keeps normal sediment from collecting in the valve.
4. Determine the length of copper tubing you need. Measure
from the connection on the lower right rear of the refrigerator
to the water pipe. Add 7 ft (2.1 m) to allow for cleaning. Use
¹⁄₄" (6.35 mm) O.D. (outside diameter) copper tubing. Be sure
both ends of copper tubing are cut square.
5. Using a cordless drill, drill a ¹⁄₄" hole in the cold water pipe you

6. Fasten the shutoff valve to the cold water pipe with the pipe
clamp. Be sure the outlet end is solidly in the ¹⁄₄" drilled hole in
the water pipe and that the washer is under the pipe clamp.
Tighten the packing nut. Tighten the pipe clamp screws slowly
and evenly so the washer makes a watertight seal. Do not
7. Slip the compression sleeve and compression nut on the
copper tubing as shown. Insert the end of the tubing into the
outlet end squarely as far as it will go. Screw compression nut
onto outlet end with adjustable wrench. Do not overtighten or
you may crush the copper tubing.
8. Place the free end of the tubing in a container or sink, and turn
ON the main water supply. Flush the tubing until water is clear.
Turn OFF the shutoff valve on the water pipe.
