SAND FILTER MAINTENANCE
The sand filter requires no special routine maintenance but its correct operation should be checked every
three months. In doing so, the level of the sand in the centre tube needs to be kept topped up. On
experience this should be topped up every year, although the amount of sand required varies from site.
The sand should be kept at level of 450mm from the steel plate. 2mm-4mm Dry Quartz sand should be
used and can be purchased from WPL directly.
