Trio Internal Power Filter Manual
Pump Maintenance
The Trio water pump requires very little maintenance, although occasionally it should be removed from the filter case and rinsed of any slime build-up that may have occurred. We recommend a bi-monthly inspection of the water pump impeller chamber. Inspect the Impeller Assembly and Ceramic Impeller Shaft Assembly for any wear.
