Why is the filter short cycling (builds pressure quickly after backwashing)?
• Refer to Hayward’s owners guide for proper backwashing procedures. It may be that you are not backwashing long enough. Always backwash until the water is clear in the multiport valve sight glass. • You may have live algae causing the filter to clog. You may also have mineral deposits building in the sand bed. • It is highly recommended that you have your water tested at your local Hayward dealer. Compare those results with your own. You may need to update your test kit or replace the testing solutions.
