What Does Backwashing Your Pool Mean

From https://www.swimmingpoolsteve.com/pag... - Backwashing is a swimming pool maintenance term used to describe the removal of dirt and debris from your swimming pool filter by reversing the water flow through it. Most commonly when the term backwash is used, it is referring to the cleaning and maintenance of a sand filter. The pool water that passes through this sand filter leaves a layer of dirt and debris on the top layer of sand as cleans the water and sends it back into the pool. To remove that accumulation of dirt and debris left behind in the filtering process, the flow of water is reversed through the filter and out through a backwash or waste port and this is known as backwashing. You will know when it is time to backwash the filter again by monitoring the filter gauge for increased pressure, normally about 7-10 psi higher that your clean operational pressure. Swimming pools should operate at a filter pressure of lower than 30 psi.
