6.6.3 General Considerations to Prevent Cavitation
Consider the following to avoid conditions that lead to cavitation.
• Regularly inspect suction hoses and gaskets to check for air leaks.
• Use the proper suction hose size and length for the pump flow rating.
• Use caution with intake valves to minimize pressure loss.
• Cavitation can also occur when air enters the pump. If an air leak is suspected, discontinue
pumping and perform pressure and vacuum leak tests.
• Low barometer from a storm and high water temperature can increase cavitation.
• Know your elevation. Pump performance is reduced at higher elevations where there is less air
pressure to push the water into the pump (similar to low barometer).
6.7. Post Operation Notes
Unless local procedures exist, perform the following steps at the end of all operations.
A. Return to idle slowly.
NOTE
Use the red idle button ONLY when an emergency exists.
B. If local procedures require storing the pump dry, drain pump.
NOTE
If salt water (sea or brackish), contaminated water, or foam solution was used; flush the
pump with fresh water.
C. Fill out pump run log. (Typically, indicating total pumping time and report all issues or
malfunctions and/or irregularities to AHJ immediately.)
