The Waterway Leaf Trap fits Sequence 750 or Sequence 1000, PerformancePro Cascade, or Tiny Might pumps, and requires a "mate adapter" to assure a snug fit.
If you will be using any of the Wave Series, Sequence 750 or Sequence 1000, PerformancePro Cascade, Iron Might or Tiny Might pumps, and are planning on placing the pump before the filtration system, it is required by the manufacturers to have a leaf trap/priming pot in order for your warranty to be valid.
The strainer basket is designed to facilitate the priming of the pump and suction line. It is not designed to remove air from the suction line. This trap will also work as a strainer basket to trap leaves and debris. Use when your pump is mounted above the water level.
