A reverse osmosis (RO) system removes particulate matter, chemicals, minerals, and other contaminants from your water. It’s necessary to perform routine maintenance on it to prevent equipment problems and water quality issues. There are simple tasks you can do yourself, but you will want to have a professional take care of more complex matters.

Replacing Filters Regularly

A reverse osmosis system uses a series of filters to remove contaminants. Replacement of these filters should occur every 6 to 12 months, depending on the type of system you have. Most RO setups will have an indicator or alarm that signals it’s time for replacement. Skipping filter changes can lead to permanent damage to your equipment, membrane problems, and water quality issues.

The type of filters you’re using in your RO system can determine how frequently they need changing. For example, a sediment or pre-filter removes large particulates before future filtration occurs. This filter generally requires more frequent replacement. Ideally, you should replace your sediment filter every 6 to 12 months. A carbon filter removes chlorine and chemicals. It requires a replacement frequency of every 6 to 12 months as well. Post filters usually last for about 12 months.

Replacement of the Reverse Osmosis Membrane

A reverse osmosis membrane is a semi-permeable barrier that allows water to pass through. However, while water passes through microscopic pores, the removal of salts, minerals, and other impurities occurs. The RO membrane usually lasts approximately two to five years before needing replacement. You may need to replace it more frequently if you notice a change in water taste or experience a reduction in flow.

Sanitizing Your RO System

You should sanitize your reverse osmosis system at least once per year. The ideal time to do this is when you change your filters. Doing so will keep the tank fresh and prevent the buildup of bacteria. Manufacturers generally recommend that you clean the storage tank once annually and replace the tubing according to that time frame as well.

Testing Water Quality

A total dissolved solids meter can check system performance. If you see a change in readings, this can indicate the need for filter or membrane replacement. You should also monitor how your water looks and tastes. Visible particulates or bad tastes indicate system performance issues.

Checking Fittings and Equipment for Leaks

Periodically inspect your reverse osmosis system for signs of leaks. This includes around fittings and connections and on the outside of the storage tank. You should also test your tank to ensure it has a pressure of approximately 7-8 psi when it is empty.
