A sand filter has laterals (plastic tubes with holes in them) in the bottom, covered with a foot or more of sand of a particular size grain. Pool water is flowed onto the top of the sand and vacuum pressure draws the water through the sand. The particles in the water are trapped in the upper level of the sand and the clean water flows through the laterals and back to the pool. As the dirt builds up on the top of the sand (the schmutzdeck) the filter actually cleans better. Once the dirt layer is thick enough to impede the flow of water, you have to remove it by backwashing. You do not want to backwash too often or you will lose the efficacy of the filter. Be sure to shut off the pump before you move the lever to backwash or you WILL crack the laterals - requiring a very expensive repair.
