Is it inadvisable to reuse PVC? (Sch-40 white stuff)
Odds are it's fine, but you have more information to make a proper risk assessment than we do - for example, I wouldn't want to reuse it in my house, around wood or other materials prone to water damage, or if I was running something more valuable or potentially harmful than just water through it; just in case it did decide to fail majorly on me. I probably wouldn't do it if the cost of fittings would be greater than the cost of the pipe, either, since if it failed I'd likely double that cost to fix it.
