TROUBLESHOOTING
1. PUMP WON’T DELIVER ANY WATER
Review priming instructions. Make sure the pump and
suction line are full of water.
2. LOSS OF PRIME
a) Check the suction line and foot valve for leaks. The
entire suction side of the system must be totally
air tight.
b) Make sure the water level hasn’t dropped enough
to uncover the suction inlet. Suffi cient pipe would
be used to prevent this from happening.
3. LOW FLOW OR PRESSURE
a) Check suction piping for leaks.
b) Check the impeller for clogging. Remove all foreign
material if it is clogged.
4. NOISE
a) Make sure pump and piping are supported.
b) Make sure suction lift does not exceed 20 ft.(6mm)
c) Check disch. piping for excessive bends or elbows.
d) Check motor bearing for damage.
