NOTE: It is not necessary to overtighten foot valve and cylinder
into pump block. O-Ring seals perform sealing function without
excessive tightening. Full thread engagement is sufficient. The
Foot V
alve may be rotated back up to 1/2 turn from full engage-
ment for convenient hose position.
For syphon hose attachment, it is critically important that the
threads of the syphon hose fit snugly into the foot valve with the
hose assembly couplings PTFE
taped and sealed to prevent air
leakage.
