  1. After you have installed your Rusco system, you can simply turn the flush valve parallel with the system when you notice excessive buildup of sediment
  2. You should clean your filter screens every few months and replace them every 6-12 months depending on your water usage

  4. The filter element may need to be removed and cleaned
  5. To remove the filter element turn off the water supply and drain water pressure
  6. Unscrew the clear cover and remove the filter element
  7. Wash off collected sediment by spraying with water
