Reverse Osmosis water treatment systems have become increasingly popular for domestic applications in recent years. These devices can provide an effective solution for some of the toughest water contaminants including lead, chlorine and other heavy metals. While these systems are extremely powerful, they still need some care and attention to ensure that they continue to deliver high quality water treatment. So, here is a basic guide to the maintenance tasks you will need to complete throughout the year. 

Changing Filters 

Reverse osmosis systems can have between three and five distinct filter stages. Each stage has its own filter, with its own purpose. To keep your RO system operating at peak efficiency and performance, these filters need to be changed regularly. Dirty filters will not only affect performance, but could also reduce your water quality significantly. Older filters will also take longer to properly treat your water, so if you notice a change in the filtration rate, it could be time for a filter replacement. Depending on the usage, filters generally need to be replaced approximately 6 months, but check your owner’s manual for specific manufacturer recommendations. 

Repair Service 

While replacing your filters regularly can keep your system operating correctly, there can sometimes be damage in other ways. Therefore, it is a good idea to ensure that your system is regularly serviced. There are some warning signs that an issue is developing and you need to schedule an appointment. One of the most common is that there is a drop in water production. If you notice that it’s taking long to fill the tank or you’ve started running out of treated water, you should call in an experienced technician, particularly if you’ve already replaced your filters and dumped out the tank.

A water treatment specialist can help with any aspect of RO maintenance including annual cleaning. Annual sanitization is an important aspect of maintaining optimum water quality. So, if you notice any water quality issues such as a chlorine taste or an odd odor, your system is not performing correctly and may be in need of cleaning.  

With the correct care and maintenance, an RO system can last many years. If you have concerns about looking after your RO system, you should consult a professional water treatment specialist for further help and guidance.
