If we had a dollar for every different way that a customer had told us how they backwash their filter we would be way too rich.

Incorrect backwashing can have a very negative effect on your pool so here’s how it should actually be done.

How to Backwash and Rinse your Pool Filter

  1. Switch the pool pump off.
  2. Move the handle on top of the filter to the ‘backwash’ position.
  3. Switch the pool pump on, and watch the sight glass on the filter. It should turn dirty and then slowly become clear again (usually 1 – 2 minutes).
  4. Switch the pool pump off.
  5. Move the handle on top of the filter to the ‘rinse’ position.
  6. Switch the pool pump on for 10 – 20 seconds.
  7. Switch the pool pump off.
  8. Move the handle on top of the filter back to the filter position.
  9. Switch the pool pump on (this is normal operating position).
