BEFORE USE
PUMP PLACEMENT
For best pump performance, place the pump near the water level, and use
hoses that are no longer than necessary. That will enable the pump to
produce the greatest output with the least self-priming time.
As head (pumping height) increases, pump output decreases. The length,
type, and size of the suction and discharge hoses can also significantly affect
pump output.
Discharge head capability is always greater than suction head capability, so it
is important for suction head to be the shorter part of total head.
