Restore High-Volume Waterfall Flow
The Atlantic Water Gardens TT4000 replacement impeller is the factory-spec service part for the TidalWave3 TT4000 waterfall and stream pump. Replacing a fatigued impeller returns the TT4000 to its rated 4,490 GPH (16,999 LPH), bringing your large waterfall or stream back to full visual impact at a fraction of the cost of pump replacement.
High-Flow Impeller Design
At 4,490 GPH, the TT4000 moves a serious volume of water. The impeller geometry is specifically tuned for the asynchronous motor's RPM and torque curve. Worn or cracked blades create turbulence that reduces both flow and energy efficiency. A genuine OEM impeller ensures the blade angles, diameter, and material match the factory specification — no guessing, no compromises.

How to Replace
Power off and remove the TT4000 from the pond. Open the volute by rotating counter-clockwise. Extract the worn impeller, insert the new one firmly, and reinstall the cover. Test free rotation before resubmerging. Spring startup is the ideal time to inspect and replace the impeller as needed.
Ideal for large pond and stream installations in the TT4000's flow range.
