Throat Packing Adjustment
When pump packings begin to leak after
much use, perform Pressure Relief
Procedure, page 11, and tighten packing nut
down until leakage stops or lessens. This
allows approximately 100 gallons of
additional operation before a repacking is
required. Packing nut can be tightened
without o-ring removal.
