Material Properties: ABS Versus PVC Schedule 40 Pipe
A 2" PVC Schedule 40 pipe has a pressure rating of 280 PSI. At 90 degrees F this should be derated to 75% of maximum, or 210 PSI. This rating applies to pressurization with water, and does not include shock. For water applications, the pipe is derated a further 72% to cover surge or water hammer conditions. This puts the rating at 150 PSI. Most of the larger pipe sizes have lower pressure ratings. PVC pipe degrades quickly when exposed to sunlight. This is not covered in the specifications that I found. In my experience, full sunlight does tremendous damage to PVC Schedule 40 pipe. For example, sunlight can cause failures in pipes that are typically carrying 40 PSI water.
