Each type of pipe has pros and cons that must be carefully evaluated to ensure effective use.

Common types of plumbing materials

Plastic pipes - Known for their corrosion resistance and lightweight nature.

  • PEX water pipe - This tubing, often used in water supply systems, is known for its versatility and flexible properties. PEX pipes also offer a more budget-friendly supply line alternative to copper.
  • PVC pipes - Rigid white plastic pipes used for drains and underground outdoor plumbing.
  • Cast iron pipes - Once the most common for your drains but being phased out due to cost.
  • Galvanized steel - Previously used for supply lines but prone to rusting.
  • Lead - Historically used in plumbing but no longer used due to health risks.
  • CPVC - Plastic piping efficiently rated for the hot cold water supply.
  • Choosing suitable pipes requires careful consideration of their intended location and function within your plumbing system. Indoor supply lines, drains, outdoor underground piping, and sewer connections all have different requirements due to their specific functions. Our team can help suggest the perfect plumbing pipes your home requires for its varied needs, including gas and water systems.

    Plastic pipes

    Plastic pipes, especially PVC and PEX, have become increasingly popular in Australian homes for their compatibility with residential plumbing systems. The lightweight, flexible nature and simplicity of installation of these pipes carry the added benefit of making them resistant to corrosion in your plumbing system. Making them ideal choices for your home plumbing requirements.

    However, it should be protected from UV light by using insulation or being buried underground.

    Rigid pipes, such as PVC, are securely joined using solvent cement, ensuring a more reliable connection compared to PEX installations.

    PEX piping, identified as a variety of cross-linked polyethylene, is pliable plastic tubing, outstanding for arrangements that encompass domestic plumbing for water heater systems, and simplifies installations around corners or in tight spots. PEX pipes, also suitable for cold hot water delivery up to 180°F, match various applications. It is chlorine and chemical resistant but like PVC, should be shielded from UV rays if outdoors.

    The primary limitation of plastic pipes is their capacity to withstand certain temperatures and pressures. Copper and stainless steel are robust materials offering more than adequate performance in plumbing under higher temperatures and pressures. The specific pipes that are the best for your system should be employed strictly within their certified performance rating.

    Your plumber can advise on the right type of plumbing pipes for your house’s bathroom based on water pressure, fixture locations, and water heaters specs.

    Overall plastic pipe systems when installed properly can be a cost-effective, low maintenance plumbing solution. When it comes to your home’s plumbing, be sure to choose the most suitable plastic material grade, thickness, and plumbing fittings fixtures for your application.

    Metal pipes

    Metal pipes, including copper, stainless steel, and galvanised steel, are commonly chosen for traditional plumbing systems. Each material, from rigid copper to flexible plastics, presents unique benefits and drawbacks.

    Copper and brass pipes are renowned for their quality and are a preferred choice due to their versatility and longevity. Copper pipes, employed for used hot water, also handle cold water consistently and at high pressure for extended periods.

    Copper stands out among piping materials for its durability, resistance to corrosion and mineral buildup, often lasting over 50 years. The main disadvantage is the expense, as copper, being a high-quality material, is costly to purchase and install.

    With its robust composition, stainless steel is an excellent option for tankless water heaters, offering durability and corrosion resistance on par with copper. Stainless steel is also suitable high temperature and pressure applications, rendering it an excellent choice for commercial settings. One drawback is that it necessitates special threaded fittings to connect to other pipe types.

    Galvanised pipes, previously common for water supply lines, are now less favoured due to corrosion over time. Eventually, the galvanised coating wears away, with the pipes rusting from the inside, causing leaks, reduced water pressure and potential contamination. For these reasons, galvanised pipes are no longer recommended for domestic plumbing.

    In bathroom plumbing, materials like copper remain reliable, whereas PEX and PVC present more cost-efficient alternatives. During a bathroom renovation, converse with a professional plumber to decide if a blend of copper pex options, or another alternative, is best for your system’s specific needs.

    Factors to consider when selecting plumbing materials

    Choosing the right plumbing pipes for your home is crucial to a functional and secure domestic plumbing system, necessitating thoughtful consideration of several important factors:

    Water type and quality - The mineral content, pH, hardness, and contaminants in your water supply will determine which pipe materials are most suitable. Copper and plastic pipes fare better with hard, alkaline water, while stainless steel handles acidic water well.

    Temperature and pressure requirements - The pressures and temperatures your hot and cold water supply can withstand will influence the choice of pipe types. Plastic pipes offer an ease of use with their lower pressure and temperature capacity compared to metal alternatives.

    Exposure to outdoor elements - For outdoor or underground type plumbing, UV and weather resistance are crucial. Various PVC compositions tolerate sun and soil well, yet in comparison, PEX does not exhibit the same resilience as a steel pipe.

    Costs - Plastic pipes can also be the most affordable, while copper pipes are moderately priced and stainless steel is a premium-priced option.

    Ease of installation/repair - Flexible plastic pipes like PEX can easily simplify installations, whereas the process of soldering copper can be more involved.

    Longevity and durability - In the long run, copper and stainless steel pipes have the most extended functional lifespans before a pipe replacement is needed.

    Noise - Plastic pipes dampen water flow sounds, while metal transmits noise through walls.

    Codes and standards - Make sure any plumbing materials conform to Australian standards and plumbing codes.

    Carefully weigh all these aspects before settling on the ideal plumbing system materials for your home. Partnering with a professional, licenced plumber is highly recommended to ensure proper selection and installation.

    Tips for choosing the right plumbing materials

    Here are some tips when evaluating options:

    • Don’t sacrifice quality solely for lower upfront costs. Higher grade, longer-lasting materials like copper can save money over time.
    • Match materials to your application’s specific temperature, pressure and exposure needs. Plastic pipes have lower limits than copper or steel.
    • For hot water lines, identify which pipes are best suited for high temperatures such as copper, stainless steel, or CPVC plastic.
    • To reduce water flow sounds, plastic pipe materials dampen noise better than rigid metal pipes.
    • If your water supply is acidic or alkaline, choose pipe materials that resist corrosion from those conditions.
    • For outdoor or underground plumbing, opt for UV-resistant PVC or stainless steel due their robustness against sun damage.
    • PEX plastic tubing, often used in plumbing for its flexibility, simplifies installations around corners, but choose copper for straight runs.
    • Consult the professionals at Padstow Plumbing to pinpoint the materials that are best for your home’s requirements.
