Note: The sand in your filter should last at least 7 years. If the pressure stays high after proper backwashing, the sand could be clogged with suntan oil or other like substances. Servicing or changing the sand should be done by a professional.

How do I backwash my sand filter?

Do in the following order:

1. Turn the pump off.
2. Turn the pool cleaner valve to the off position.
3. Stretch the backwash hose out to where you want to discharge the water.
4. Rotate the handle on the front of the filter to the open position and pull it up until it stops.
5. Turn the pump on and run until the water coming out of the hose turns clear (approx. 30-60 seconds).
6. Turn the pump off.
7. Return the valve on front of the filter to the down and locked position.
8. Turn the pump back on and reset your pool cleaner valve to it's operating position.
9. Observe the filter pressure. If it is higher than it should be, repeat the backwash procedure.
