NOTE:
1. The charts are based on using NSF approved #20 sand in the filters. Variation in
sand media may affect pressure differential values.
2. These charts are for pressure drop through the tanks only. Depending on the location of the
pressure gauges, there will likely be additional contributors to the pressure differential, such
as valves, fittings, etc.
