    Aug 10, 2016 PVC pipe often gets a bad rap because it cannot handle as much pressure as various types of metal pipe. However, smaller sizes of PVC pipe, especially schedule 80, can handle plenty of pressure for most home and business uses. Unlike tensile strength, burst pressure decreases as pipe size increases.
