18-04-2014Gravity feed is used on filter 1, filter 4, and filter 5. Filter 2 and 3 are fed by a small Direct current 12 volt pump that feeds water to them through a float valve system. Both ways work as long as the surface of the sand remains undisturbed. An overflow will allow the unfiltered water that flows in too fast to simply flow into your unfiltered storage tank.

Sand Media Filters
The recommended rate for "average water" is 20 to 25 gallons per minute; for clean water (less than 10 ppm of suspended solids), the rate is 25 to 30 gallons per minute. An excessive filter flow rate can reduce the filtering ability of a sand media filter by forcing larger particles to pass through.

Rapid vs slow filtration
There are two main types of sand filters that are used for water treatment: rapid sand filters (also known as Rapid Gravity Filters or RGFs) and slow sand filters. Sand filters should not be confused with Roughing Filters, which tend to be horizontal-flow gravel filters used as a roughing treatment for turbid raw waters prior to sand filtration.
