🔍 Key Concepts

• Centrifugal and reciprocating bilge pump operation – what a good vacuum tells you about the suction side • Flow path through a bilge system – suction → pump → discharge valve/line → overboard • Difference between suction blockage and discharge blockage and how each affects vacuum

💭 Think About

• If the pump is developing good vacuum, what does that say about the condition of the suction line and strainer? • Would a blockage on the suction side usually increase or decrease vacuum at the pump? Why? • Which component, if blocked, would let the pump pull hard (good vacuum) but still prevent water from leaving the system?

✅ Before You Answer

• Confirm what good vacuum physically means at the pump inlet (air is being removed and suction line is tight). • Decide whether a clogged suction strainer would allow a good, steady vacuum while moving no water, or cause loss of suction. • Consider which downstream component, if obstructed, would stop flow but still let the pump draw water into itself and maintain vacuum.
