In order to replace your reverse osmosis filters, first close the main shutoff valve for your reverse osmosis system and close the blue handled valve on top of the water holding tank. Open the faucet to relieve the water pressure in the reverse osmosis system.

Unscrew and remove each filter housing, one at a time, replace the water filter, and reinstall the filter housing using the wrench supplied with your system. When you tighten the water filter housings DO NOT over-tighten, you can crack the plastic or flatten an O-ring and cause your system to leak.  You will want to be near a sink or have a bucket to dump the water out of each housing as you remove it. (Changing filters one at a time will help avoid placing filters in the wrong position.)

Once all prefilters are replaced, remove the 10” inline post filter, it will either have a ⅜” push fit connection or ¼” female pipe threaded and included John Guest ¼” and ⅜” push fit connections by male pipe thread.

Replacing the Reverse Osmosis Membrane

If changing a reverse osmosis membrane, do it while the post filter is disconnected. Remove the tubing from the membrane housing cap (the thicker end of the housing with only one tubing connection), unscrew the membrane housing cap, and pull out the old membrane, you may need to use needle nose pliers to get a good grip on it. Insert a new membrane, trim ¼” off the end of the tubing and reinsert it into the fitting.

Once all water filters and the RO membrane have been replaced and housings have been tightened, before you turn the water back on, open the valve on top of the water storage tank and open the reverse osmosis faucet.  This is so you can drain the water leftover from the storage tank so it will rinse the carbon dust from the new post filter. After a few minutes, the tank will be empty.

Close the water storage tank valve. Turn on the main water supply valve, it can be tested by unscrewing the blue cap from the side of the holding tank and checking the pressure using a Schrader (the same valve as car and bicycle tires) tire pressure gauge. The pressure should be 7 – 8lbs.

Pressurizing Your Reverse Osmosis System

After 10 minutes, open the water storage tank valve and allow the tank to fill for 2 hours before using it. If you changed the reverse osmosis membrane, drain the first tank of water and allow it to fill again before using the water.
