I was told to replace a chill water pump this weekend by my employer. Old pump was ran with welded steel pipe. New pump had an offset that would require repiping. I was told to repipe with pvc. When it came down to it, the only fittings available were some sch 80 and some sch 40. I know steel pipe would have been the best repair, but that wasn't an option here. Pump supply is 65psi. Chill water 45*. Inlet 3" ; discharge 1.5". How long should I expect this pvc to hold up? I have seen it ran like this before, but with a lot of problems (easily broken).
