Reverse osmosis to refrigerator connection is possible depending on the refrigerator type and RO system model.
However, we want to draw your attention to a few things you should keep in mind.
3 Things to Keep in Mind Before Making The Connection
1. Check for Compatibility
Some refrigerator companies will let you know if their products are not compatible with RO systems due to a difference in pressure. This is because for the water valve to operate as it should, the fridge has to be pressurized at a higher PSI (pounds per inch) than what RO systems are able to deliver on their own.
That being said, there is a workaround for this which involves using bypass plugs. However, we don’t encourage going this route and suggest that you always refer to your appliance’s manual and the manufacturer’s recommendations.
2. Purge the RO System
Before connecting an RO system to your fridge, you’d need to first purge the system. Purging the reverse osmosis system before connecting to a fridge is essential to prevent excess carbon from the system from clogging the fridge, especially if the fridge has a built-in water filter.
You’d may also need a filter bypass plug for some refrigerators. This will ensure that the system will work without clogging up. The plug you need will vary depending on the model of your refrigerator and the reverse osmosis system. Some refrigerators work seamlessly and don’t require bypass plug.
3. Pay Attention to the Water Line Distance (and the Pressure)
The way reverse osmosis works when connected to a fridge is; the water line is fed to the RO system, and then the filtered water line goes through a tube and into the refrigerator.
Running a long water line might end up disrupting the water pressure. So, it’s important to keep the water line between the water source (tap), RO system and refrigerator as short as possible.
How to Connect a Reverse Osmosis System to Refrigerator
Okay, we can finally start connecting the system to the fridge. Feel free to consult a professional if you’re not comfortable following these steps on your own.
- The first thing that you should do is shut off the cold water line that is feeding your RO system.
- Next, locate the tube that should extend from the RO system to the faucet. Remember to place a container under that tube in order to keep the surface beneath it dry.
- Cut the tube to required measurements. This all depends on where the tube comes out of your RO system, how long the tube is, and the space you have. The system will be able to drain the water straight into the container below through the tube.
