Superior filtration from the inside out
The Pro Series S166T Filter features an integral top diffuser that evenly distributes unfiltered water over the sand media in a cascading, umbrella-like pattern.
This allows the greatest filtration possible from every square inch of sand.
The self-cleaning underdrain assembly, with its 360&#deg; slotted laterals, provides a fast, balanced flow of clear water back to the pool while allowing more thorough backwashing.
Best of all, the S166T's full-flow technology reduces your energy costs because the filter operates for shorter periods.

Seven-position valve
The patented, multiport control valve was designed with seven pool filter positions.
An easy to use lever-action handle lets you quickly dial any function.

Long lasting convenience.
The S166T's assembly can be easily accessed via the unique folding ball joint in the laterals.
A corrosion-proof housing protects the filter from severe weather for years to come.
