DOs

  • Install product according to the manufacturer’s installation instructions.
  • Follow recommended safe work practices.
  • Make certain that thread sealants, gaskets, and or fire stop materials are compatible with Corzan® CPVC.
  • Use only latex-based paints if painting is desired.
  • Keep pipe and fittings in original packaging until needed.
  • Cover pipe and fittings with an opaque tarp if stored outdoors.
  • Follow proper handling procedures.
  • Use tools specifically designed for use with plastic pipe and fittings.
  • Use proper solvent cement and primer and follow application instructions.
  • Cut the pipe ends square.
  • Deburr and bevel the pipe end before solvent cementing.
  • Rotate the pipe 1/4 turn when bottoming pipe in fitting socket (applicable for 4” and smaller pipe sizes).
  • Avoid puddling of solvent cement in fittings and pipe.
  • Follow the manufacturer’s recommended set and cure times prior to pressure testing.
  • Fill lines slowly and bleed the air from the system prior to pressure testing.
  • Use only insulation and/or heat tracing approved for CPVC piping.
  • Allow for movement due to expansion and contraction.
  • When making threaded transitions from metal to plastic, thread plastic pipe into metal fitting.
  • Follow support spacing recommendations for specific temperature and gravity of process fluid.

DON'Ts

  • Do not use petroleum or solvent-based paints, sealants, lubricants or fire stop materials.
  • Do not use both Teflon® tape and thread sealants simultaneously.
  • Do not use solvent cement that exceeds its shelf life or has become discolored or gelled.
  • Do not use solvent cement near sources of heat, open flame, or when smoking.
  • Do not pressure test until recommended cure times are met.
  • Do not use dull or broken cutting tool blades when cutting pipe.
  • Do not install Corzan® CPVC pipe in cold weather without allowing for expansion.
  • Do not thread any Corzan® Schedule 40 pipe.
  • Do not thread Corzan® Schedule 80 pipe larger than 4”.
  • Do not pressure test using compressed air or gas.
  • Do not use Corzan® CPVC for compressed air or gas systems.
  • Do not thread metal pipe into plastic fittings.
  • Do not anchor the pipe so that it can’t expand or contract.
