Welcome to Starmatrix News, today we’re going to teach you how to backwash your sand pool filter.

      Backwashing reverses water flow to remove contaminant buildup in your sand filter, which is an essential part of pool maintenance. You are supposed to backwash the filter when the filter gauge pressure reads above 1.5 bar or you notice a weak flow of water out of your return jets (however you’ll need to backwash more often if you have an algae-infested pool or you’ve just used a pool flocculant).

      First, turn off your sand filter. Then, take your backwash hose and hose clamp and place it firmly over the backwash nozzle. Make sure to screw the hose clamp tightly.

      Next, turn your multi-port valve from filter to backwash. Now, turn on your sand filter.  Let this run for about a minute or until the sight glass is completely clear.

      Turn off your sand filter and move the multi-port valve from backwash to rinse.

      Turn on your sand filter.

      Let this run for about 30 seconds.

      Turn off your sand filter.

      Then, take your multi-port valve from rinse to filter.

      Now turn back on your sand filter.
