The Pooled Energy control system will recommend a backwash roughly every 4-6 weeks in summer, based on sensor readings of the water flow through the filter. The exact frequency will depend on the  particular pool, its situation and usage.

More frequent backwashing offers little benefit in energy consumption, but does increase the consumption of pool chemicals and tends to destroy the filter media. Please do not backwash more than once a month, unless otherwise requested by Pooled Energy, or if it is obviously needed.

Please note that your pressure gauge is not a good indicator of when you need a backwash.  The reason is that Pooled Energy uses true variable speed pumping at a much lower pressure during normal operations.

Sand/media filters have a sweet spot where they filter best and, surprisingly, this is when they are slightly to moderately dirty.  As the filter dirties up, the gaps between the grains of sand (or the glass filter media that Pooled Energy uses by preference), get smaller and the filter operates better….until it finally clogs up and has to be backwashed.
