The softrinse system is designed to be simple, yet through in removing minerals from municipal water sources, all while being careful not to jeopardize water pressure. A dockside hose is connected to the stainless water inlet fitting. As water first enters the 3 way valve its then routed through the 20 micron carbon pre filter, this first step removes sediments, chlorine, volatile organic compounds (VOCs), and also helps remove taste and odors. This important pre filter also helps to protect the resin media in the softener tank. Next, the pre filtered water is sent to the resin media tank where its then filtered through the 10,000 grain resin media. This process removes minerals commonly found in municipal water. These minerals include calcium, magnesium, iron and other minerals which are harmful to your boats finish. The (softened water) then exits the system through the stainless water outlet fitting. The end result is water that’s not only much more effective but also safer for your boats finish all while preventing aggravating water spots.
