Revolutionising Plumbing with Plastic

Plastic pipes are transforming the plumbing industry. They offer a durable and cost-effective solution for modern construction needs.

The rise of plastic in the plumbing industry

The journey of plastic pipes in the plumbing industry began in the 1930s, marking the start of a significant transformation. Advances in plastic technology during the 1960s further accelerated their popularity among plumbers.

This shift was largely due to plastic’s versatile properties, including corrosion resistance and flexibility. Such features made them an attractive alternative to traditional materials like copper and galvanised steel.

Over time, the use of types such as PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), and HDPE (high-density polyethene) became more widespread. Their ability to join with both other plastics and metal pipes without harmful chemical reactions has revolutionised building practices.

Today, these materials are chosen for various applications, from water supply and drainage systems to complex municipal water projects, showcasing their integral role in modern plumbing solutions.

Comparing Plastic and Copper Plumbing

Exploring the differences between plastic and copper plumbing reveals insights into their use in homes. Keep reading to find out more about how they measure up.

Performance and durability of plastic pipes

Plastic pipes, such as PVC, ABS, and CPVC, offer flexibility and resistance to corrosion from chemicals found in household water. This makes them ideal for carrying hot and cold water in residential settings.

Despite their resilience against chemical wear, these pipes can be more prone to physical damage. Impacts of heavy pressure can cause cracks or breaks more easily than in some harder materials.

Copper pipes excel over plastic ones, withstanding higher water pressures at room temperatures without deforming or breaking. While copper remains a durable choice capable of lasting many years under proper conditions, plastic plumbing systems might require more frequent checks and potentially earlier replacement due to their susceptibility to impact damage.

This highlights the importance of considering the environment they’ll be used in and the expected longevity when choosing between plastic and copper piping for plumbing projects.

Ease of installation

Installing plastic pipes presents a smoother process compared to their copper counterparts. This is largely due to their flexibility, allowing easier handling and fitting into tight spaces without complex tools or techniques.

On the other hand, copper systems demand soldering joints together – a method that requires additional time and a specific skill set.

This straightforward approach saves significant time during installation projects. For example, PVC pipes can be joined with solvent cement, eliminating the need for brazing or filler metal, as seen in copper installations.

Similarly, cross-linked polyethene (PEX) tubing offers methods like compression fittings or heat fusion, further streamlining plumbing tasks. This simplification makes plastic piping an attractive option for DIY enthusiasts and reduces labour costs on larger construction sites.


Plastic pipes offer a more budget-friendly option compared to copper. The affordability stems from less expensive plastic, making the initial installation costs significantly lower.

For instance, PEX pipes, widely used in various plumbing setups due to their flexibility and resistance to corrosion, are, on average, 25 per cent cheaper than their copper counterparts.

Choosing plastic over copper cuts down on upfront expenses and reduces routine maintenance needs. Unlike metal options that can rust or corrode over time when exposed to water, plastic remains resistant.

This durability means fewer replacements and repairs, further stretching the homeowner’s budget. Whether for pipework in modern homes or updating older systems, opting for materials like PVC or HDPE ensures cost savings without compromising quality.

Comprehensive Comparison of Plumbing Pipe Types

Various pipe types stand out in exploring plumbing materials for their unique features and applications. Here’s a concise comparison crafted to highlight the distinctions and similarities between commonly used plumbing pipes.


Type Material Applications Advantages Disadvantages
PVC Polyvinyl Chloride Drain lines, vent lines, water supply lines Corrosion-resistant, durable, cost-effective Can become brittle over time
PEX Cross-Linked Polyethylene Water supply lines Flexible, less expensive than copper, easy to install Cannot use outdoors due to UV sensitivity
ABS Acrylonitrile Butadiene Styrene Drain lines, vent lines Impact resistant, handles cold temperatures well Not as temperature resistant as PVC
CPVC Chlorinated Polyvinyl Chloride Hot and cold water lines, industrial liquids Handles high temperatures, safe for drinking water More expensive than PVC, can split if frozen

This table summarises the pivotal aspects of each plumbing pipe type, shedding light on their materials, common uses, benefits, and potential drawbacks. Each pipe type offers unique advantages for specific applications, highlighting the importance of selecting the right material for your plumbing needs.

Understanding Plastic Plumbing Joints

Exploring the various plastic plumbing joints reveals their unique roles in building efficient systems. These joints connect pipes securely, ensuring smooth water flow and preventing leaks.

Types and applications

Plastic plumbing joints are crucial in ensuring efficient and leak-free pipe connections. They come in various types, each serving specific purposes across the plumbing and heating industry.

  1. Slip joint: Ideal for sink drains and other easily accessible areas, it allows for simple disconnection and cleaning.
  2. Threaded joint: Commonly used for connections that might need to be undone. Suitable for water heaters or washing machines.
  3. Solvent-welded joint: Creates a permanent bond between pipes by melting the plastic. Perfect for PVC and ABS pipes in drainage systems.
  4. Compression fitting: This type relies on a nut to compress a ferrule onto a pipe, ensuring a tight seal. Great for places where soldering is not possible.
  5. Flanged joint: Utilises bolts to connect two sections of pipe. Often seen in large commercial applications.
  6. Union joint: Designed for situations where future disconnection of the pipes might be necessary, such as near water meters or shut-off valves.
  7. Barbed fitting: Works with flexible plastic tubing, securing it with clamps or crimps—a favourite for irrigation systems or pools.
  8. Push-fit fitting: Offers quick installation by simply pushing the pipe into the fitting—an excellent choice for DIYers needing quick repairs.
  9. Electrofusion fitting: It uses electricity to heat and join HDPE pipes, which are vital for gas supply lines due to their leak-proof nature.
  10. Mechanical coupling: Connects different types of pipes together, like cast iron to plastic, making it versatile across repairs and installations.
  11. Crimp fitting: This requires a special tool to crimp metal rings around PEX pipes, which ensures secure connections in hot and cold water lines.

Each type serves an essential purpose within plumbing systems, whether facilitating repairs, connecting different materials, or ensuring durable installations in harsh environments.
