Troubleshooting
Leaks
Make sure that the tubing, the water fittings, and the quick disconnects inside and outside of the pump are not
leaking.
Damage to the high-pressure water seals and the hoops is the most common cause of water leaking from the
intensifier. Water dripping from the high-pressure cylinder shows that the seals will soon require changing. One
drop every few strokes means that the seals should be watched. More than 1 drop with each stroke means that
the seals in that high-pressure cylinder should be changed at the first opportunity.
Weep holes throughout the high-pressure water system let water escape from leaking parts. A leak can mean that
there is a faulty part, a loose fitting, or a damaged seat.
Water can enter the hydraulic system if the weep holes in the dynamic seal backup or the seal housing are
blocked. Make sure that the weep holes are free of debris.
Look for leaks at both ends of the high-pressure cylinder.
CAUTION
Failure to correct the cause of a leak can cause damage to the fittings.
