When replacing the impeller the gasket between the pump
case and the cover should be replaced as well. So when
ordering a spare impeller order a gasket as well. Remove
the cover to get access to the impeller. Remove the old
impeller with the help of two screwdrivers. Install the new
impeller and add some grease. Turn the blades in the
direction of rotation of the pump i.e. anti clockwise looking
at the impeller.
