发明名称 Apparatus and method of water treatment with preliminary screen
摘要 The present invention provides a water treatment system, such as a water softener, with a resin tank having a top distributor with a preliminary screen and second screen. The preliminary screen provides added protection by reducing the chance of larger particles from entering the various valves and screens. Prior to the regeneration cycle, an additional back wash and fast rinse cycle are added to rinse sediment to the drain and to clean the preliminary screen.
