Backwashing Instructions for a diatomaceous earth (D.E.) filter with a dial valve.

  1.  Turn off the pump & rotate the valve  to the Backwash position.
  2. Turn on the pump for approximately 1.5-2.0 minutes.
  3. Turn off the pump & rotate the valve to the Rinse postion.
  4. Turn on the pump for another 30 seconds.
  5. I recommend this be done anywhere from 1-4 times or until the site glass is relatively clear.
  6. Turn off the pump & rotate the valve  to the Filter position.
  7. Turn on the pump & make sure the pool is circulating.
  8. Add  the D.E. slurry mix to the skimmer with the pump on.
