How to prevent water dispenser and ice make problems.

If the water supply to your refrigerator's ice maker and water dispenser isn't set up properly, it can lessen or completely stop ice production, slow the flow of water from the dispenser, cause dripping, or affect the flavor of the water or ice.

Here's how to keep the water flowing smoothly.

Check the water pressure to your refrigerator

Your water supply needs water pressure between 30 and 120 psi to operate a water dispenser or ice maker. Your 1/4-inch water supply line to the refrigerator should dispense at least 9 ounces of water in 5 seconds.

Check the water connection

Connect your refrigerator to a cold water supply only and check all connections after installation to ensure there are no water leaks.

Get the right supply valves

For best results, uses a 1/4-inch saddle valve that requires a drilled hole — it's less likely to clog. Self-piercing and 3/16-inch valves are not recommended, because they clog more often.

Have a long enough water line

Have enough additional supply line behind the refrigerator that you can easily pull it out for cleaning without stretching the line and causing kinks. However, ensure the tubing does not bang against the back of the refrigerator or wall when the refrigerator is pushed back in place. This can cause unnecessary noise when water runs through the line.

Replace the water filter

Many refrigerators have a water filter to improve the taste and odor of the water and ice. Replace the refrigerator water filter every 6 months so it can do its job well, Check your owner’s manual for more information about your water filter.

If you take the appropriate steps to ensure an adequate water supply to your refrigerator, you can expect optimal performance of your ice making and water dispensing systems for many years to come.
