BEFORE USE
POSITIONING THE PUMP
For optimum performance, place the pump near the water level and use
hoses that are no longer than necessary.
As “head” (pumping height) increases, pump output decreases. The length
and size of the suction and discharge hoses can also effect pump output.
The discharge head is always greater than the suction head, so it is important
for the suction head to be the smaller part of the total head.
