Priming and Storage of the Water Pump
The term Self Priming is actually an industry term that describes the ability of a pump to create a partial vacuum by purging air from the intake hose and pump casing. All Honda pumps are self priming by definition. All self priming pumps require water to be added to the pump casing to start the priming process.
Priming Tips Back to Water Pumps
Place the pump as close to the water source as possible. The less lift
required will improve priming time
Fill the pump case completely with water (Never operate a centrifugal
pump without water in the pump casing)
Start the pump engine
By partially restricting the discharge hose, priming time can be
improved
Shutting off a pump will allow water to flow out of the suction hose,
requiring priming.
The use of a foot valve on the end of the suction hose will prevent
water from flowing out of the suction hose if you stop the pump and reduce
time required for the pump to regain its prime.
Wear off the volute and Impeller can decrease pump performance and increase time required to prime the pump. Regular inspection and maintenance of your pump will maintain peak performance
