If you use the super-economy stuff this may be true because it is only
rated at 180 or 200 psi. I don't see why it should'nt be reasonable to
use schedule 40 PVC which is rated at 480 psi and only costs about $.15
per foot (1" dia). If you're still paranoid, you could get schedule 80
PVC rated at 630 psi at about 50% more cost.
