The central element of any reverse osmosis water filter is the semi-permeable reverse osmosis membrane. Of course, the membrane alone is not sufficient to deal with every and all types of tap water contaminants, which is why most reverse osmosis filters are complex, multi-stage systems that comprise several types of filter media (e.g. activated carbon, ceramics, polypropylene, etc.) to achieve the in-depth filtration reverse osmosis systems are known for.

The maintenance of a reverse osmosis filter involves the periodic replacement of the filter cartridges that make up the system along with the replacement of the RO membrane. While replacing the filter cartridges in a reverse osmosis system is a straightforward and simple process, replacing the RO membrane follows a slightly different procedure.

Users of reverse osmosis water filters seldom encounter any problems with these drinking water systems, in fact, they’ll work for many years on end before anything malfunctions. However, you may encounter certain issues with certain models, so it’s always good to be prepared for unforeseen events.

In this article, we’ll focus on offering troubleshooting tips for two of the most common malfunctions you may encounter as a user of a reverse osmosis water filter system – little to no flow coming from the faucet and water continuously flowing to the drain. Here’s how to troubleshoot reverse osmosis water filters should you ever come across these two issues:

Reverse osmosis water filters are complex, multi-stage systems that are recognised as one of the most efficient filters for removing even the most problematic contaminants. RO filters don’t require intense monitoring, however – as with any water filter – you need to change the filter cartridges and the RO membrane that make up the system. Sometimes, you may also need to clean the storage tank and monitor the health of your filter cartridges and reverse osmosis membrane. To help you better maintain your system, here are some of the must-have accessories for your reverse osmosis filter:

TDS meter

Expressed in mg/L or ppm (parts per million), total dissolved solids (TDS) refer to the total amount of dissolved minerals, salts or metals, anions or cations in a given volume of water. When TDS levels rise in your water, it’s an indication that your water has certain contaminants in it. A TDS meter can help you measure the level of total solids in your water, and determine whether your RO membrane and pre and post-filter cartridges need replacing.
