Location Indication Comments
Sealing Head
Water leaking from the weep
hole in the sealing head
Seat in the discharge check valve
is not sealing properly
Make sure the gland nut is
tightened to the proper torque
specification.
Inspect the seat, sealing head and
gland nut for cracks.
Internal crack in sealing head
Replace the sealing head.
A cracked sealing head can result
in water leaking from the high
pressure outlet passage to the low
pressure inlet passages.
The sealing head body can
become extremely hot.
Improper torque on gland nut
Tighten the gland nut to the
proper torque specification.
Erosion or scratches on the
contact surface of the sealing
head, or on the gland nut where
the seat makes contact
Polish the surfaces following the
procedure, Sealing Head
Maintenance.
Water leaking from the weep
hole in the gland nut
High pressure piping gland nut is
not tight and is not sealing
properly
Tighten the gland nut to the
proper torque specification.
Improper high pressure piping
connection
Check the number of exposed
threads past the collar on the high
pressure piping. Only 1-1/2 to 2-
1/2 threads should be exposed.
Check high pressure piping for
damage, cracks or deformation.
Inspect the gland nut for
deformation of the threads.
Damaged sealing head gland nut
Check the gland nut for cracks
due to fatigue. If cracks are
detected, replace the gland nut.
