I have some salvaged PVC (Schedule 40) from a run in the irrigation system that I'm rebuilding which is now unused - I'm considering reusing it in the rebuild of the system. Is this foolish?
The salvaged section is SCH-40 pipe from Charlotte pipe, and has some ASTM info on it. I can post a picture if it will help. I could use this 'salvaged' pipe in either the primary part of the system (if acceptable), or in a side-bar to the primary system which is purely accessory, or not at all.
I'm guessing it's likely better to use fully-new pipe and connections in the work I'm doing now, as it should significantly reduce the likelihood of leaks in the new work. If this is the case, I'm happy to hear it, but I'd also like to know what the potential issues of re-using old PVC is, as there is a solitary long run that is non-essential where it would be useful to have a reduction in cost (as small as it may be). Plus it could always go to another project (like watering the garden, or something similar), if the risk is mostly to critical/annoying-to-fix situations like deeply buried irrigation.
