Using a reverse osmosis system on your refrigerator
Connecting a refrigerator to a reverse-osmosis system could lower the water pressure to the refrigerator, which could result in small or thin ice cubes, low or no ice production, or slow or no water being dispensed.
IMPORTANT: The pressure of the water supply coming out of a reverse osmosis system and supplying 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 home 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).
Tips for using a reverse osmosis system:
- 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.
If you still have questions regarding your water pressure, call a licensed, qualified plumber.
