Plumbing System Materials โ€” What to Specify & Source

Residential plumbing covers every pipe, fitting, valve, pump and water heater that moves clean water in and waste water out of a home. This hub explains what to specify for each part of the system โ€” material, diameter, pressure rating and code fit โ€” so contractors can build a complete, correct bill of materials.

Water Supply Pipes

Pressurized pipe that delivers potable hot and cold water to fixtures.

PPR PipePEX PipePVC PipeCPVC PipePB Pipe

Key specs to confirm

  • Material (PPR / PEX / PVC / CPVC) vs. water temperature
  • Nominal diameter and wall thickness (pressure series)
  • Pressure and temperature rating for hot lines
  • Connection method (fusion, crimp, solvent)

Specification dimensions are general engineering guidance โ€” confirm exact values against your project drawings and local code.

Drainage Pipes

Gravity pipe that carries waste water and soil to the sewer or septic.

PVC Drainage PipeUPVC PipeHDPE Drainage

Key specs to confirm

  • Diameter by fixture load and run length
  • Slope / fall requirement
  • Material (uPVC / HDPE) and joint type
  • Vent and trap arrangement

Specification dimensions are general engineering guidance โ€” confirm exact values against your project drawings and local code.

Plumbing System FAQ

What pipe material is best for home water supply?
It depends on temperature and budget: PPR and PEX suit hot and cold potable lines, PVC/CPVC are common for cold and drainage. Confirm the pressure and temperature rating against the run before ordering.
How do I size a residential water pipe?
Size by fixture demand and acceptable pressure drop over the run length. Use the House Material Calculator for a planning estimate, then confirm with an engineer for the final spec.
Do you supply the whole plumbing package?
Yes โ€” because our team also designs residential MEP systems, we can supply pipe, fittings, valves, pumps and water heaters against one coordinated spec, not as a loose catalog.

Need the full Plumbing package?

Our engineers spec the system, then we supply every material against that spec.
