Refrigerator - Installing Reverse Osmosis with Refrigerator Filtration

We do not recommend installing a reverse osmosis system on a refrigerator that has a water filtration system already installed. Most refrigerators made nowadays feature an integrated water filtration system in the refrigerator.

Installing a Reverse Osmosis System On a Refrigerator That Has Water Filtration

In order for the water valve to work properly, the refrigerator filtration system requires a minimum water pressure of 40 pounds per square inch (PSI). The pressure from the reverse osmosis system will be approximately 1/2 of the original house water pressure. This reduction in water pressure can result in smaller ice cubes as well as hollow ice cubes which in turn will increase the likelihood that the dispenser will become jammed more often on models equipped with ice and water dispenser through the door.

For example, if the house water pressure before installing a reverse osmosis system is 60 PSI, the pressure coming out of the reverse osmosis will be 30 PSI. This low pressure can cause small/hollow ice cubes.

Note: If you have a refrigerator filter and you would like to use a reverse osmosis system, it is not necessary to use the refrigerator filter. We recommend that you remove the filter and install the by-pass plug supplied when you purchased your refrigerator.
