POSSIBLE CAUSE
Locate and remove the obstruction. See the corresponding section
of this manual for instructions on how to disassemble the pump.
Try to prime the pump again. Check the intake system for air leaks.
Check the impellor for wear on the seals.
See repair instructions.
Inspect and repair.
Compare the pressure and flow of the pump on the pump curve.
Check that the valve on the discharge is not partially or fully closed.
Reduce the pressure requirements of the installation.
Locate and remove the obstruction.
Check the intake pipe for obstructions, leaks, open by-pass valves, etc.
If necessary, reduce the flow by partially closing the discharge valve.
Install the pump as close as possible on the vertical line of the
intake tank.
