💧 What an “Open Backwash” Means Backwashing a sand filter is the process of cleaning the sand inside by reversing the water flow — sending water upward through the sand instead of downward. This lifts and flushes out the dirt, debris, and oils that the sand has trapped, sending them out through the waste line. ☎️ 076 279 9291 | Mypoolshop
