How to Ensure Correct Water Pressure

How to Ensure Correct Water Pressure for your Refrigerator

Having correct water pressure will help with proper water dispensing and ice production.  If you suspect you might have decrease water pressure, check the following: 

  • A cold water supply with water pressure between 30 and 120 psi (207-827 kPa) is required to properly operate the ice maker.
  • Make sure that the water shutoff valve is fully opened.
  • Make sure the water supply line is not kinked. A kinked water line will reduce water flow.
  • Check the water filter.  If the water filter is clogged it will decrease the water pressure.
  • Using a reverse-osmosis system. 

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

Tips for using a reverse-osmosis system

Connecting a refrigerator to a reverse-osmosis system could also lower the water pressure to the refrigerator, which will result in small ice cubes or low ice production. 

  • The water pressure to the reverse-osmosis system should be at least 40-60 psi (275-414 kPa).
  •  If connected to a reverse-osmosis system, the following items may improve the water pressure:
    • Allow the storage tank for the reverse-osmosis system to refill after heavy use.
    • If the refrigerator also has a water filter, remove it.
    • Make sure the sediment filter in the reverse-osmosis system is not blocked and replace if necessary.
