Investing in a reverse osmosis (RO) filtration system for your home makes good sense. This is a great way to remove up to 99% of contaminants without adding any chemicals to your water supply. This is an entirely mechanical process and the need for maintenance is pretty low. But, like any system, there are some regular maintenance tasks that need to be carried out in accordance with your owner’s manual. In this article, we will look at the importance of RO system maintenance and offer three tips to help you keep your system working efficiently.

The Importance of Regular RO System Maintenance

When your RO system is well maintained it will have peak performance and produce very high quality water. The lifespan of the system can be prolonged and the system could last for 10-20 years. Bacterial growth can be prevented with regular maintenance which makes the drinking water even cleaner. Certain contaminants, such as calcium, magnesium, chlorine, iron, and others can foul the system and create scale. This can lower the efficiency of the membrane and lead to a reduction in water quality. When the RO system is working efficiently the water output can be maintained which means that you will always have a ready supply of clean drinking water. Regular maintenance will reduce the need for more expensive repairs and it’s a proactive way to protect your investment.

1.  Regular Filter Changes

Most modern reverse osmosis filter systems have more than one filter installed. The typical configuration is a sediment filter, followed by a carbon prefilter, then the RO membrane filter, and a final post filter to give the water a final polish. Every filter serves a very specific need within the system as a whole but the overall goal is to produce high quality water for drinking and cooking. So, it’s important to change these filters regularly or they can be fouled and the volume of clean water will be diminished. Eventually, the RO system may be unable to produce clean water because the filters are compromised. Check your owner’s manual to find the frequency of intervals and other details on filter replacement.

2.  Draining the Storage Tank

This is a pressurized tank that is usually installed under the sink to store the purified water. The RO process takes time, it cannot be an on-demand solution, but sometimes the water can sit in the tank for a while. This can reduce the freshness and you can mitigate this by draining the tank every couple of weeks as part of a cleaning routine. As an added bonus this will aid the RO membrane when the water pressure is applied to clean the impurities from the surface. The water you collect from the tank is clean and you can use it on your plants or for other cleaning tasks safely.

3.  Sanitizing the Storage Tank

The water storage tank can be a source of pathogens, such as bacteria. This can produce sludge or slime in the tank and it’s important to sanitize it once per year. When you sanitize the tank you need to use an NSF approved sanitizing product or an unscented bleach.
