Graded Silica Sand Media for Pool Filters

Silica Sand Grade 16/30 for Swimming Pool Sand Filters 25kg Bag During filtering operation, dirty water from the pool comes in through the filter’s inlet pipe of the multiport valve, which leads to the water distribution head inside the tank. While gravity pulls the water down through the sand, the tiny sand particles catch any dirt and debris. At the bottom of the tank, the filtered water flows through the pick-up unit and out the outlet pipe. Over time, the collected dirt and debris in the sand slows down the water flow. Pressure gauges on the Multi port Valve give an idea of the blockage/ restriction level inside. Once the pressure rises (normally by around 30-40KPA above baseline) it’s time to backwash the filter.
