Corrosion resistance: Corrosive substances and bacteria in the ground can attack water supply pipes—especially metals. This shortens the working life and limits the effectiveness of the fire protection system. However, CPVC is designed to resist the wide range of soil pH and salinity found in the ground, ensuring a longer lifespan, preventing excessive maintenance costs, and controlling risks.
Cost isel: Mae pibellau cyflenwi dŵr metel a PVC yn gofyn am ddefnyddio blociau gwthio, ychwanegiadau drud a ddefnyddir i atal y bibell ac atal difrod rhag symudiad heb gefnogaeth. Os na ddefnyddir bloc byrdwn, bydd y bibell gyflenwi dŵr metel yn symud yn rhydd, gan achosi i'r ffitiadau wahanu, gollwng a difrodi pibellau cysylltu eraill. Nid oes angen defnyddio blociau gwthio ar brif gyflenwad dŵr CPVC, gan leihau cost gyffredinol deunyddiau.
