IMPORTANT: An air leak in the suction line will prevent priming, and reduce
the performance of the pump.
3. Pay particular attention to the following:
• Always ensure the hose adaptor sealing ring is in place and correctly
fitted.
• Always use a flexible hose at the pump body connection of at least
1ft (300 mm) length.
• Keep all pipes/hoses as short and straight as possible and avoid
sharp bends. If a flexible hose must be laid across a roadway,
protect it with planking.
• Ensure there is adequate drainage for the discharged water, and
that there is no danger of damage to property as a result of the
pumping activity.
NOTE: Instantaneous shut off pressure, applied when a vehicle runs
across an unprotected hose, will cause “hydraulic shock”, which
can damage the pump and/or the hose.
4. Attach the inlet strainer to the end
of suction hose using a further
hose clamp, to prevent large
stones etc, from being drawn up
which could cause severe
damage. Keep the strainer free of
debris.
5. If it is likely to clog with dirt or
debris, proceed by either:
• preparing a bed of stones on
which to rest the strainer.
• tying the strainer so that it stays off the bottom of the pit, pond or
excavation.
• rest the strainer inside a basket or bucket to keep undue debris
away.
