Insert the white valve into the pump body,
so that it fits securely into the small round
hole. Make sure the pointed side of the
valve is facing down.
Fit the clear silicone diaphragm into the
pump body. Ensure a perfect seal around
the rim by pressing down with your
fingers.
(This is easier if assembled while
the diaphragm is wet.)
