Video Step-by-Step Guide: Changing Filters on a Reverse Osmosis System


Maintaining your reverse osmosis system is crucial for ensuring clean and pure water for your household. In this guide, we’ll follow the instructions provided by Lisa Bauer from Simple Water Softeners on how to change the filters on a reverse osmosis system. Follow these steps to keep your system running efficiently.



Step 1: Locate Your Reverse Osmosis Unit

Your reverse osmosis unit is typically located in the back left or right-hand corner of your cabinet. Gently pull it out, aligning it with the cabinet for easier access.

Step 2: Remove the Cover

Squeeze and pull the cover of the unit to remove it. The cover should come off easily, exposing the filters and components inside.

Step 3: Turn Off Water Supply

Locate the water supply valves on top of the unit. Turn them clockwise to shut off the water supply. Remember, when the valves are sideways, they are off; when they’re straight, they are on.

Step 4: Release Pressure

Turn on the water faucet connected to the system. This step helps release the pressure in the system. Although not much water will come out due to the cutoff, it’s an essential precaution.

Step 5: Remove Old Filters

Identify the filters that need replacement. Firmly squeeze and pull the little belt to remove each filter. Hold the filters in a way that minimizes water dripping by placing your thumb strategically.

Step 6: Install New Filters

Take the new filters and carefully slide them into place. Ensure they are properly seated. The little belt will lock them into position. Double-check that the arrow on each filter aligns with the flow direction.

Step 7: Reconnect Components

If your system has a John Guest Quick Connect, follow Lisa’s advice. Make sure there’s no gap between the gray and white components. Push the tube in as far as it will go on both ends.

Step 8: Turn Water Supply On

Turn the water supply back on slowly. Allow the system to fill up, and drain it by turning on the faucet for about four minutes. This process helps remove excess carbon from the filters.

Step 9: Wait for System to Fill

Wait for at least an hour and 10 minutes, allowing the system to fill up completely. You can wait longer if needed.

Step 10: Drain the System Again

Turn on the faucet again, and if the water appears black, don’t worry. It’s normal and part of the process. Drain it again and clean any mess with alcohol.

Step 11: Check for Leaks

After securing the system, push it back into place and check for leaks. Use paper towels to ensure everything is dry. Monitor for the next couple of hours and check again the next day.

Step 12: Replace the Cover

Once you’re confident that everything is in order, replace the cover on your reverse osmosis unit, and you’re done!

Regular maintenance, as demonstrated by Lisa Bauer, will keep your reverse osmosis system working efficiently, providing you with clean and healthy water for years to come.
