Excessive glue is specifically documented as a failure mode for CPVC pipe in CPVC installation/design manuals. Excessive glue can weaken the pipe and cause pipe fractures and premature pipe failures. More glue is not better. Photographs below document poor quality work. These observations are outside the scope of NFPA 25 inspections.
The photograph below shows not only poor quality work (excessive glue on the exterior of the CPVC pipe) but a catastrophic fracture failure as a result of tension overload from ice impingement (freeze-up). Speculation is this section of piping froze previously, was repaired, then froze again. A extensive section on freeze failures will be developed for this blog at a later date.
The following photos show correct glue work:
