Restore Full Flow to Your TidalWave3 Pump The Atlantic Water Gardens TT1500 replacement impeller is the factory-matched service part for the TidalWave3 TT1500 waterfall and stream pump. Over time, impellers wear or accumulate mineral deposits that reduce flow. Swapping in a fresh impeller restores the pump to its rated 1,640 GPH (6,209 LPH) output without the cost of a full replacement pump. Why Replace the Impeller The TT1500 uses an asynchronous motor design that spins the impeller at very high efficiency. When flow drops noticeably or the pump runs louder than usual, the impeller is the first component to inspect. This genuine replacement part ensures exact clearances and blade geometry, so your stream or waterfall returns to full performance after a simple quarter-turn swap.

Twist the front housing counter-clockwise to release the volute. Pull out the worn impeller, drop in the new one, and reassemble. Rinse the pump before returning it to service. Ideal for annual spring startup maintenance or any time output drops below expectation. Ideal for pond owners who want to extend the life of their TT1500 rather than replace the whole unit.
