Replace the washer in the hose fitting or
replace the hose.
The inlet hose is clogged.

surface.
Notch the end of the inlet line where it meets
the flat surface, use suction rated hose.
The impeller, body, and end cover are worn
from pumping abrasives.
Replace the pump.
The impeller blades are missing or charred
from dry running.

is too small and/or the pump is too high
above the liquid surface.
Use appropriate hose and pumping setup
to maximize performance.
