How to Maintain My Reverse Osmosis System

A reverse osmosis system uses a filtration method that removes particles from drinking water by using pressure applied to filters and membranes to push through clean water. Most systems use three stages to filter the water; pre-filter, reverse osmosis and post-filter. Reverse osmosis can remove particles so fine that it is used to purify sea water into fresh water. A reverse osmosis system is expensive, so regular maintenance is required to ensure all the parts are working. To maintain your system, replace the filters of the device every 12 to 18 months. Replace the filter membrane every 24 to 60 months.

Reverse osmosis systems purify the water coming from your sink.

Shut off the water to the sink by turning the water control valve.

Turn the valve of the reverse osmosis system to the off position and open the product faucet to release any water.

Unscrew the filter canisters from the unit by turning with your hands. Use the model number of the filter to order new filters.

Remove the new filters from their box. Hold each filter by the shipping wrapper to prevent contamination of the filter. Screw into place by hand and test the unit.

Unscrew the top of the reverse osmosis unit and pull out the membrane with a set of pliers. Center the new membrane into the center of the system and push it in firmly.
