This is the first of four posts in a CPVC piping failures series by Donald B. Snell, PE.

CPVC AdvantagesCPVC piping failure

There are many advantages of using Chlorinated Poly (Vinyl Chloride) (CPVC) piping (such as domestic water, condensate drain piping, and fire sprinkler piping) in building systems. These advantages include:

  • Lower cost
  • Ease of installation
  • Physical properties such as corrosion resistance and flame and smoke spread ratings
  • Service life

However, while there are many advantages, owners should also be aware of potential compatibility issues and risks associated with contamination, which could lead to failure and/or decreased service life.

Owners out of necessity should take on this responsibility because designers are not aware (or are not as aware as they should be) about these compatibility issues and risks.
