Each pump body in the Guzzler G2
SapPuller
pump features a pair of
valves (a total of 4 for the pump). A valve is fastened between the
pump body and each of its inlet and outlet ports.
(Figure 14)
Valves are typically replaced in pairs; i.e., the inlet and outlet valve
of a given pump body are replaced at the same
Ɵ

When replacing a pair of pump valves, it is best that
only one valve
is removed and replaced before a
