The water treatment process to get water that meets the requirements of drinking water is carried out using sand filters as the main ingredients in addition to gravel, charcoal, and fiber. This water treatment can effectively produce drinking water that is needed, the use of a filter for a long time will cause blockage by dirt stuck on the surface of the sand filter, so it cannot be used continuously without being cleaned regularly. This study aims to determine the water pressure needed to clean the dirt that clogs the sand filter and the length of the filter washing cycle. Using laboratory experiments on a J-shaped filter container model of cross-section plastic pipe 07.5 cm, 010 cm, 015 cm, and 020 cm filled with sand grading 0.15 to 0.6 mm as thick as 50-60 cm, channeling pressurized water through the outlet into the sand filter and out through the overflow pipe. The results showed that a water level of 200 cm above the datum was able to push dirt and clean the filter after being pressed for 600 seconds.
