Keep Your Waterfall Running at Peak Flow The Atlantic Water Gardens TT2000 replacement impeller is the genuine OEM service part for the TidalWave3 TT2000 waterfall and stream pump. Replacing a worn impeller restores the pump's full 2,640 GPH (9,993 LPH) output for a fraction of the cost of a new pump. Signs You Need a New Impeller If your TT2000 is running but flow has dropped significantly, or if you hear an unusual grinding or rattling sound, the impeller is likely worn or fouled with debris. Hard water deposits can also lock the impeller in place over winter. A genuine replacement restores the tight tolerances and blade pitch required for the TT2000's asynchronous motor to deliver full rated performance.
