Picking the Perfect Plumbing Pipes

Found a water leak in your home and now you have a choice: PEX or Copper.

Here’s the lowdown on these two common piping materials!

Copper Pipes:


  • For many years, copper piping has been the standard for water pipes throughout a home.
  • Copper creates a biostatic atmosphere that prevents the growth of most bacteria.
  • Copper is very resistant to corrosion.
  • This pipe material is also suitable for use outdoors because it is not affected by ultraviolet rays.
  • Copper comes with an extremely long lifespan


  • Copper has become increasingly expensive over the years.
  • Depending on the PH levels of the water where you live, copper piping could corrode.
  • While it shouldn’t be a problem in the Sydney Metro, frozen water can cause copper pipes to burst.

PEX (crosslinked polyethylene):


  • PEX piping is very affordable, costing only a third of copper piping
  • Pipes are more resistant to freezing and bursting
  • Resistant to scale and chlorine
  • Quick and easy to install; fewer connections and fittings
  • Pipes don’t lose heat the way copper pipes do
  • PEX pipes are often colour coded in red (meaning hot), blue (meaning cold) and white (meaning either) for convenience and quick identification


  • PEX is not suitable for outdoor use
  • Prone to damage from rats gnawing on the piping
  • Cannot be recycled and will have to be completely replaced
  • The impermeable membrane increases the possibility of water contamination
