8. Remove the two o-rings from the draw
valve.
Note: To remove o -rings, use a clean,
sanitized towel to grasp the o-ring. Apply
pressure in an upward direction until the o -ring
pops out of its groove. With the other hand,
push the top of the o-ring forward and it will
roll out of the groove and can easily be
removed. If there is more than one o -ring to be
removed, always remove the rear o-ring first.
This will allow the o-ring to slide over the
forward o-rings without falling into the open
grooves.

the retaining pin, mix inlet adaptor, valve
cap, pump gasket, and the piston.
Remove the o-ring from the piston and
