High-Pressure Plumbing Weep Holes - Hypertherm HyPrecision 100D Instruction Manual

7.11 High-Pressure Plumbing Weep Holes

Weep holes throughout the HP water system relieve the water seepage from any leaking components
(for example, see Check Valve Assembly). Seepage from any of the holes indicates a faulty
component, loose connection, or damaged seat. Failure to correct the cause may result in damage to the
mating fittings.
If weep hole leakage is observed, the fitting may have loosened and it will need to be tightened. Another
cause of seepage is the collar on the tubing may need to be threaded further onto the tubing. Persistent
seepage may require replacing the fitting or tube.
Lubricate the high-pressure fittings with a HP grease such as Blue Goop. To minimize side load, use
two wrenches to tighten the high-pressure fittings: one on the gland and the other on the fitting.
