This demonstration guide answers one field question about weep holes that show packing failure. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with weep rate after a pressure cycle. That reading separates weep holes that show packing failure from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the packings as the primary path. If it is in spec, do not replace the packings just to complete a parts list.
Repair the failed system
The usual correction is the packings, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about weep holes that show packing failure.
Stop before you make it worse
Do not sealing weep holes with silicone. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the packings is corrected, convert the visit to a broader diagnosis rather than stacking parts.
