Flush Valves are great for prolonging the life of your reverse osmosis membrane. They allow water to bypass the flow restrictor and flush your membrane of any possible built up minerals deposits that could lead to poor performance and possible failure.
Installing a flush valve only takes a few seconds, and all you need to is locate your RO systems waste water line and replace your current flow restrictor with a RO Membrane Flush Valve. Most reverse osmosis systems have a barrel type flow restrictor that is easy to locate and replace. However, some do have a capillary style that is found inside your systems waste water line, and can be a little harder to locate.
Once your old flow restrictor is removed, you can then install the new flush valve, making sure to take the flow direction into account. Reverse Osmosis Membrane Flush Valves come in many different flow ratings, and selecting the correct one for your system is critical for optimal performance. In most cases, a 75-90 gallon per day membrane will require a 550mL/min flow restrictor.
One the flush valve is installed we suggest opening it for about 30 seconds before and after each use for maximum efficiency.
