CLEANING THE PUMPING
CHAMBER
Debris such as weeds, sand and other solids may be-
come trapped in the water hose and pumping chamber.
This can reduce pump performance. It is important that
the pumping chamber be kept clean at all times. The
chamber can be cleaned as follows:
1. Remove motor and impeller by removing the two
M12 × 1.75 Hex Head capscrews.
2. Remove all debris from the pump screen.
3. Thoroughly clean the volute and impeller. Do not
remove the impeller unless necessary for repair or
replacement or to remove trapped debris.
4. Assemble the motor and impeller to the volute.
Clean the capscrews and lubricate the threads with
underwater grease before installation.
5. Remove all debris from the hose. Otherwise, solids
will backll the pump.
