Today I got a call from one of my A List customers to come in and replace some air lines. So I went in to check out the project.
The entire shop had been plumbed in Sched 40 pvc..about 500 ft of it, most at least 14' off the floor. It blew out yesterday about quitting time. No visible shrapnel, but the shock was such that it catastrophicly disassembled itself in at least 5 seperate areas breaking branch lines loose, drains sagging and broken..the normal.
The plastic was brittle. Cutting a chunk with a PVC cutter simply caused it to snap to pieces rather than cut. Looks like compressor oil damage.
All of it had been hung with plumbers strap, and no signs of abrasion were noted. Im unable to tell where the plumbing failed first, but no where was there any possibliity of it being struck.
So for the next few day$, Ill be hanging off a forklift and a really shitty ladder installing all new 3/4" black pipe, area drains, sand blaster runs, a number of CNC machines, etc etc.
A good reason not to run PVC pipe.
