Sta-Rite System: 3 Sand Filters

Sand is the most widely used filtration method for swimming pools. Convenience, low maintenance and water quality are the reasons for sand’s popularity. The System: 3 sand filter is a time-tested favorite with pool owners for its simple maintenance, easy-to-operate control valve selector and outstanding water clarity. The biggest reason for installing the System: 3 - the additional leisure time you’ll spend enjoying your pool.

System 3 brings you the proven performance of Sta-Rite's sophisticated sand filter hydraulics in the world's safest and easiest to operate filter. Its sophisticated design yields a uniform flow pattern.  Sta-Rite's sophisticated under-drain design has a proven performance record of greater sand bed depth penetration, more thorough backwashing and long cycle times.

Special lateral design provides superior flow characteristics and long filter cycles for economical operation. Use coarse aquarium sand or 100 lbs. clean pea gravel and the balance in coarse aquarium sand (requires: StaRite backwash valve).
