To keep the system running as smoothly as possible, we recommend cleaning the flow control insert once a year. Below, we'll tell you more about how it works and how to clean it.
How It Works
The Flow Control Insert is an essential part of the Reverse Osmosis system. Not only does it control the volume and speed of drainage water, but also keeps water pressure flowing through the filters. If the flow insert is dislodged or clogged, it can deter the unit from producing water. We don't want that! So let's learn about how to clean it.

1. We need to stop water flow to begin. You can either turn the feed water off to the system or remove the Prefilter to stop water production. The prefilter is the first filter. Grab a hold of the filter and twist it counter-clockwise to remove.
2. Now, we'll locate the gray elbow that attaches the red hose to the filter assembly.
Note: If the unit is older and doesn't have a gray elbow, the flow control insert is located inside the end of the red hose (where it connects to the housing).
3. To access the insert, remove the gray elbow from the system by pushing IN on the red collet port, and pulling OUT on the gray elbow.
4. The insert should be inside the gray elbow. Go ahead and take the insert out. Note: If it's not in the elbow, it may be stuck inside the red collet port on the filter assembly. No worries! You'll just want to use a needle nose pliers or tweezers to help remove it.
5. Now you'll examine the insert and remove any sediment or dirt restriction. You should be able to see through the center hole of the insert with nothing blocking it.
6. Once you've cleaned it and you're ready to put it all back together you'll push the insert back into the gray elbow nice and securely. Place the red collet port back into the filter assembly if you removed it in step 4.
7. Almost done! Go ahead and push the gray elbow back into the red port.
8. Lastly, you can now turn the feed water back on or screw the Prefilter back on - by lining it up with the system and twisting it clockwise on. You may want to monitor the system for the next few hours just to make sure it's working smoothly.
