The Pooled Energy control system will recommend a backwash roughly every 6-8 weeks, based on sensor readings of the flow and power consumption of the filter. The exact frequency will depend on the particular pool, its situation and usage.
frequent backwashing offers little benefit in energy consumption, but does
increase the consumption of pool chemicals and tends to destroy the filter
Sand 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, these 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.
Please don’t do extra backwashes.
