Tips for backwashing your sand filter

If your sand filter has a pressure gauge, check it before you begin backwashing. The pressure should be at least 10 PSI higher than the normal operating pressure. If it's not, clean the filter elements according to the manufacturer's directions.

To start backwashing, turn the valve to the BACKWASH position and let the water run for about two minutes. Then turn off the pump and let the water drain out of the tank completely.

Once the water is out of the tank, open the air relief valve to release any built-up pressure. Then unscrew the lid of the tank and remove the diffuser.

Inspect the diffuser for any dirt or debris that may have accumulated during operation. Clean it off if necessary, then replace it and screw the lid back on tight.

Turn on the pump and let it run for a few minutes to re-prime itself. Then turn off the pump and put the valve in the FILTER position. Your sand filter is now ready for normal operation!

When should I backwash sand filter?

As a general rule, you should backwash your sand filter once every 1-2 weeks. However, if your pool is used frequently or if you live in an area with a lot of debris, you may need to backwash more often.

If you are unsure how often to backwash your sand filter, consult your owner's manual or ask a professional for advice.
