or adjusted as necessary
if:
Water leaking into the cavity past
the seals (packing) is normal. The
pump is designed such that
accumulated water will be drained
from the cavity through the plastic
drain tube to the ground. However,
as the packing and plungers wear
from normal operation, the water
leakage will become more severe.
When the drain tube can no longer
accommodate the flow, the cavity
will fill with water, which could enter
the crankcase and contaminate the
oil.
If the water level rises near the
plungers, the packing and the
plungers, if scored, must be
replaced. Report this condition to
unit maintenance.
