Understanding Swimming Pool Sand Filters, Swimming Pool Filter Sand, & Your Pool Filter System.
Water is pushed through the sand in the housing and is removed by a set of lateral tubes on the bottom.
The dirty water goes into the top of the filter, is pressed through the sand and exists out the bottom as clean water.
Ever had an "espresso" from a coffee place?
Pool sand water filters work on the same concept.
Let's dig a bit deeper into your sand filter.
As your pool filter becomes clogged with waste and debris, the pressure increases and the water flow lessons. Your filter should have a PSI/pressure gauge that will tell you the pressure.
This requires the pool owner or operator to backwash every few weeks or when needed, depending on the water flow.
Please remember that excessive backwashing may cause a loss of sand which in turn will reduce the effectiveness of the sand filtration process. The measurement from the top of the sand to the top of the filter is called the "freeboard". Check your owner's manual for the correct measurement.
The freeboard is, in my opinion, one of the most important, yet, THE most overlooked aspect of sand filter maintenance.
Please be aware of proper pool sand filter maintenance.
Should you find your sand filter low, simply get the proper grade of sand and top off the filter following the manufacturer’s instructions.

Above Ground Filters - Choosing above ground swimming pool filters can be an issue, but which one to pick.
In terms of cost and efficiency for swimming pool filter systems, a sand filter is probably the least expensive but least effective at removing those very small particles.
You also want to gauge your pump motor to fit your filter. Too many people believe that "bigger is better" and that's true in some cases but not for sizing filter motors.
There are huge calculations for this process, but the short of it is this: You want a water turnover rate of about 8 - 10 hours.
