    The backwash is an intense rinsing and tossing of the medium that lasts for several minutes. In a standard residential filter, a typical backwash lasts about ten minutes. After the backwash, the control valve initiates a “rinse” of the bed during which water flows downward through the medium, up through the riser tube, and out the drain.

    Filter channeling is when pockets form in the sand bed to allow water to channel through faster, unfiltered. It causes an uneven distribution of water within the filter, and often a noticeable difference in filter pressure. Another contributor to filter sand channeling is a plating out of calcium carbonate, caused by a high LSI in the water. 5:01
