How to Check the Water Supply Line
How to Check the Water Supply Line for your Whirlpool Refrigerator
Maintaining a steady water supply line to refrigerator appliances like your Whirlpool refrigerator is essential for optimal performance, especially if you rely on its ice and water dispensers. Checking the water supply line for refrigerator functionality regularly can prevent potential disruptions. If the water line is not installed correctly, kinked, or damaged, it could lead to no ice production, water not dispensing, or leaking. Review the Installation Instructions or Owner's Manual for specific information about your Whirlpool refrigerator.
Understanding the Water Supply Line
The water supply line to the refrigerator is usually made from PEX or copper. It connects your refrigerator to your home's water source, featuring components like the shut-off valve, tubing, and connectors. Familiarizing yourself with these parts aids in identifying and resolving issues to maintain a steady water flow.
Common problems with the water supply line include kinks, leaks, or clogs. Kinks can restrict water flow, leaks can cause water damage, and mineral buildup, especially in hard water areas, can obstruct flow.
Was the water line installed correctly?
The refrigerator must be installed to a cold water supply for the ice maker and water dispenser to work. To connect the shutoff valve and the refrigerator, use 1/4" (6.35 mm) O.D. (outside diameter) soft copper or PEX tubing. It is recommended to leave a coil of copper or PEX tubing (service loop) to allow the refrigerator to be pulled out of the cabinet or away from the wall for service or routine cleaning. Water supply lines can be purchased at Whirlpool Purchase Genuine Parts.
Check to make sure there are no kinks in the water supply line. A kink can reduce water flow. Straighten the water source line to restore adequate water flow and pressure. To help reduce the chances of a pinched water line, do not push the refrigerator too far back against the wall or cabinet.
Is the correct type of saddle/shutoff valve installed and fully opened?
Installing the incorrect saddle valve can lead to low water pressure. Be sure to use a ¼" type valve that requires a drilled hole. Do not use a piercing-type or 3/16" (4.76 mm) saddle valve, as these reduce water flow and are more easily clogged. Before purchasing or installing, ensure that a saddle-type valve complies with your local plumbing codes. We recommend contacting a licensed plumber if you have questions or concerns regarding your home's plumbing.
Is the water supply cracked or damaged?
If water appears to be leaking from the back of the refrigerator, ensure that the water line from the household water supply to the refrigerator is not damaged or cracked.
Check all accessible connections, such as the connection at the supply valve and the connection point of the supply tubing onto the back of the refrigerator. Ensure the tubing is firmly inserted into all fittings and all fittings are tightened.
- Unplug your refrigerator for safety and locate the water supply line, typically connected at the back via a refrigerator saddle valve.
- Look for visible damage, such as cracks or kinks. If found, it might be time to replace the line. Replacement parts can be purchased at Whirlpool Purchase Genuine Parts.
- Check connections at both the refrigerator and the wall for leaks. Tighten any loose fittings, especially at the valve for the refrigerator water line.
