Use this to increase the RO output of your current system by 75 GPD! This kit comes with a membrane housing, 75 GPD Dow Filmtec membrane, , 2 feet of tubing, 75 GPD membrane flush kit, and all fittings necessary to add it onto your system including the membrane clips. You simply clip the new membrane housing to your existing one and hook up the necessary lines to upgrade your system. It's just that simple!!! Now there is no need for T fittings and ball valves this is an all in one flush kit and flow restrictor! Just turn the valve to flush for 5 minutes turn it back and go! Highly recommended. The manual flush kit works by bypassing the flow restrictor on your RO system and allowing a fast high speed flow of water to pass over the membrane surface and clean off any debris or scale that would otherwise clog and shorten the life span of your RO membrane. Our membrane flush kit will give you the ability to clean the membrane and improve the life and quality of your RO membrane. Now we have the newest design available. Flow restrictor and flush kit all built into one easy to use unit! Includes everything you need to install it.
