Water Supply Requirements 

A cold water supply with water pressure 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.

NOTE: If the water pressure is less than what is required, the flow 
of water from the water dispenser could decrease or ice cubes 
could be hollow or irregular shaped.

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).

■

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 use. The tank capacity could be too small to keep 
up with the requirements of the refrigerator. 

NOTE: Faucet mounted reverse osmosis systems are not 
recommended.

■

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.

■

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.

Gather the required tools and parts before starting installation. 

■

Flat-blade screwdriver

■

⁷⁄₁₆" and ¹⁄₂" open-end wrenches or two adjustable wrenches

■

¹⁄₄" nut driver

NOTE: Do not use a piercing-type or 

³⁄₁₆" (4.76 mm) saddle valve 

which reduces water flow and clogs easier. 

Connect to Water Line

IMPORTANT: If you turn the refrigerator on before the water is 
connected, turn the ice maker OFF.

1. Unplug refrigerator or disconnect power.

2. Turn OFF main water supply. Turn ON nearest faucet long 

enough to clear line of water.

3. Use a quarter-turn shutoff valve or the equivalent, served by a 

¹⁄₂" household supply line. 
NOTE: To allow sufficient water flow to the refrigerator, a 
minimum 

¹⁄₂" size household supply line is recommended.   

 

 

4. Now you are ready to connect the copper tubing to the 

shutoff valve. Use 

¹⁄₄" (6.35 mm) OD soft copper tubing to 

connect the shutoff valve and the refrigerator.

■

Ensure that you have the proper length needed for the 
job. Be sure both ends of the copper tubing are cut 
square.

■

Slip compression sleeve and compression nut onto 
copper tubing as shown. Insert end of tubing into outlet 
end squarely as far as it will go. Screw compression nut 
onto outlet end with adjustable wrench. Do not 
overtighten.
