What is the purpose of backwashing?
Advanced Water FiltersIn backwashing, the water goes down the riser tube; lifts and turbulates the carbon with the water coming out of the backwash drain line. The tank is filled 2/3 full of carbon, which allows the remaining 1/3 as a freeboard area - room for the carbon to swirl around without being forced out the backwash line. A top screen on the valve head protects the valve head from any carbon lodging in it.

Then, turn the handle on the top of the valve from "filter" to "backwash." This reverses the flow of water and instead of spraying water over the sand, it pushes water down the standpipe, which forces the sand to be flooded with water, essentially lifting all debris out of the sand and filter.
