Sand Filter Basics - Sand filters are among the oldest form of water filtration dating back thousands of years. Ancient Egyptian writings documented the practices of purifying water by filtering it through sand. This process has remained a cornerstone in water filtration even today. Sand filters are simple, effective, and require very little attention.


How A Sand Filter Works - In swimming pools, water is pumped into a large tank that is filled with #20 Silica sand. As the water enters the top, a diffuser sprays the water out evenly across the top of the sand bed, ensuring perfect distribution.This water settles down through the sand bed entrapping the debris and returns back to the swimming pool filtered.
As the amount of debris, hair, bugs, algae, oils and more increases, the sand starts to become clogged. This restriction is noticeable on the pressure gauge located on the filter tank. The increase in tank pressure indicates the the filter is in need of cleaning or back-washing. The back-washing process rinse the sand of impurities and allows the water to flow freely again. The ease of flow lowers the pressure within the tank and the process  starts over again. Keep in mind that the more a sand filter plugs up, the finer the particulates that are captured so its ok to let the pressure climb some, and not backwash too frequently. Normal operating pressure varies by filter but typically it runs between 10-20 psi. When the pressure within the tank increases by about 10 psi or more, back-washing is needed. Allowing too much pressure to build in the tank can damage the pump and possibly the filter tank.

Cleaning The Sand Filter - To clean or back-wash a sand filter, cut the power to the pump and set the control valve to backwash, then turn the pump back on. The filter will now rinse the sand within the filter tank, sending dirty water out the back-wash port. This water can be directed away from lawns, flowers or gardens as it is chlorinated and may cause damage to plant life. This is done simply by using a backwash hose attached to the back-wash port. Continue to backwash for about two minutes or until the water runs clear through the sight glass if equipped. Shut the pump off again and return the control valve to filter mode.

Sand Filter Efficiency - Sand will filter down to about 20 microns. This is small and enough to capture most all impurities in your pool water. Sand filters will becomes clogged and cakes up over time due to the accumulation of oils, lotions hair and other debris. Even with regimented maintenance the sand within the filter tank should be replaced every 3-5 years for best results.

Changing The Sand - To empty or change the sand you disconnect the hoses or PVC piping from the filter tank. Next remove the control from the tank top and begin the manual process of scooping the sand out of the tank. Some pool professionals and pool owners turn the tank on it's side and use a water hose to spray it out of the tank. Once the sand is removed you can replace it with #20 Silica sand in the required amount dictated be the manufacturer. Use care to fill the tank and keep the sand from entering the pipe in the center. Once full of sand, replace the control valve and tighten the band. Reconnect the hoses or piping and you should be set to operate the filter once again.
