Water Pressure

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
827 kPa).
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
System.”

If you have questions about your water pressure, call a licensed,
qualified plumber.

Connect the Water Supply

Read all directions before you begin.
IMPORTANT:

■

Plumbing shall be installed in accordance with the
International Plumbing Code and any local codes and
ordinances.

■

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
above freezing.

■

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 1

¹⁄₄

" (12.7 mm to 31.8 mm) vertical cold water

pipe near the refrigerator.
IMPORTANT:

■

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 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

have selected.

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
overtighten.

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.

Connect to Refrigerator

1. Create a service loop (minimum diameter of 2 ft [61 cm]) with

the copper tubing. Avoid kinks when coiling the copper
tubing.

2. Remove the plastic cap from water valve inlet port. Place a

compression nut and sleeve on the copper tubing.

3. Insert the end of the copper tubing into the water valve inlet

port. Shape tubing slightly so that the tubing feeds straight
into the port to avoid kinks.

4. Slide the compression nut over the sleeve and screw into the

water valve inlet port.
