A flush valve temporarily allows a higher flow of water through the system to flush minerals and organic contaminants (including microbes) away from the RO membrane. Periodic flushing significantly increases the longevity of the RO membrane and can improve system performance (see the maintenance section below). The RO membrane is the most expensive component of the system and therefore a manual or automatic flush valve is a good option to reduce operational cost. A flush valve can still be installed even if you already purchased a system without one. | A flush valve temporarily allows a higher flow of water through the system to flush minerals and organic contaminants (including microbes) away from the RO membrane.

A flush valve is an optional component since an RO system will function adequately without it. In fact, most home RO systems on the market do not have a flush valve. The sellers obviously prefer that you buy expensive replacement RO membranes more frequently rather than perform preventative maintenance to extend the membrane life. | A flush valve is an optional component since an RO system will function adequately without it.

'''Manual:''' As the name implies, a manual flush valve must be opened and closed by hand whenever you need to flush the system. It's easy—just turn the valve 90°, but you need to remember to use it. | '''Manual:''' As the name implies, a manual flush valve must be opened and closed by hand whenever you need to flush the system.
