Switch the pump back on for about 30 seconds to rinse the grids from the “normal” filter side. Step 6: Turn equipment back on and run the second cycle. Step 5: Rotate the valve to the "Rinse" position. If you have a sight glass, you will see the water change from cloudy to clear as it flushes out. Turn the pump “in reverse” and run it for 1-3 minutes to strip the old DE powder and impurities off the filter grids. Step 3: Turn equipment back on and run the first cycle. Be sure the handle is pressed down all the way as you rotate it. For multiport valves, push the handle down and rotate valve to the backwash position. Lock it into position so it doesn’t slide up during operation. Step 2: Rotate the valve to the “Backwash” position.įor slide valves, turn backwash handle and pull the valve piston straight up to the backwash position. Don’t change modes of operation on the valve with the pump on, or you can damage the spider gasket in the valve. Shut off the pump at the main power switch or, even better, at the circuit breaker box. This will restore your filter to its highest efficiency to circulate your pool water and keep it healthy.įollowing a handful of easy steps for a standard three-cycle backwash is usually effective in keeping your DE filter clean: Step 1: Turn off pool equipment. By changing the direction of the water, you can knock off the caked-on DE powder that has accumulated impurities from your pool water and flush it out. The grids get caked with the powder that collects impurities to keep the water in your inground pool or above-ground pool crystal clear and to help maintain your filter’s pressure.Īre you noticing cloudy or dirty pool water? Or are you seeing a pressure gauge reading 10 psi higher than normal? These are strong indicators that it’s time to “recharge” those grids by backwashing your DE filter to strip off the current power and replacing it with a new coat.īackwashing a DE pool filter is the act of reversing the flow of water inside your filter tank. This powder works with a specific type of filter that pushes the pool water through a set of grids. Guide to Cleaning Pool Filter Cartridgesĭiatomaceous Earth (DE) is made of pulverized plankton fossils (called diatoms) that coat the filter element and acts as a filtration medium.
