How does an old fashioned hand pump work?
On the up stroke of the piston the foot valve opens and suction brings water into the pump head. On the following down stroke of the piston the valve on the piston opens up and allows water to flow above the piston. On the successive up stroke of the piston water is pushed out of the outlet.
How do you prime a hand pump well?
To prime the pump, pour water in the top of the pitcher pump until it runs out of the spout. Wait 5 minutes until the cup leather swells enough to make contact with the pump wall.
