At the forefront of heating and plumbing solutions, we proudly present our latest innovation – the STH Westco Multilayer Pipe System.

Engineered to meet the most demanding high-pressure applications, the system offers a comprehensive range of piping components and advantages for the professional installer. WRAS-approved, this cutting-edge product is engineered to ensure ultimate durability and flexibility.

In this handy guide, we explain more about the composition and applications of the STH Westco Multilayer Pipe System, and set out the key features and benefits of this advanced heating and plumbing solution.

What are multilayer pipes?

The STH Westco Multilayer Pipe System includes a diverse range of pipes and fittings, meticulously designed to ensure complete reliability across a wide array of hot and cold-water distribution applications. Manufactured under a single roof, the individual components seamlessly complement each other, guaranteeing optimal performance.

Crafted from tough, durable, lightweight plastic, the Multilayer Pipe System offers a simple and cost-effective installation for both residential and commercial projects, including:

  • As a pipe for hot and cold water distribution of potable and food-safe water
  • As a pipe for radiator-fed high-temperature heating systems*
  • As a pipe for low-temperature heating and cooling systems
  • As a compressed air pipe in systems with preceding oil filter (oil-free)
  • As a rain water piping system inside buildings and separately installed from drinking water installations (the pH-value of the water must be higher than 6).
  • In industrial pipeline systems for food, electrical, and chemical transportation
  • In condensed, filtered, and mineral water pipeline systems
  • In high-pressure air duct systems
  • In agricultural pipeline systems.

*System separation is required for specific solar and district heating systems.

The benefits of using multilayer pipes in plumbing and heating installations

The STH Westco Multilayer Pipe System offers a multitude of advantages over traditional materials like copper, including corrosion resistance, prolonged lifespan, and minimal maintenance costs. The plastic pipe system also ensures stable physical properties and high chemical stability, reducing the risk of failure. Its resilience against weather and water, coupled with superior insulation properties, positions it as the preferred choice for professional installers aiming to deliver lasting, robust results.

The system also offers a range of additional benefits for plumbing and heating installers, including how easy it is to use. Super flexible and adaptable to a wide range of property designs, the Multilayer Pipe System is also space-saving due to its lightweight, modular construction.

An environmentally friendly choice

Plastic gets a bad rap when it comes to the environment. But the STH Westco Multilayer Pipe System emerges as an environmentally friendly alternative to traditional copper pipes for several compelling reasons.

  • Resource Efficiency. Being lightweight, plastic pipes require fewer raw materials during manufacturing compared to the production of copper pipes. This results in reduced resource consumption.
  • Plastic pipes are corrosion-resistant, ensuring a prolonged lifespan without degradation, thereby minimising the overall environmental impact associated with frequent replacements and service-related emissions.
  • Reduced Transportation Emissions. Plastic pipes are lighter than copper pipes. The lower weight contributes to lower fuel consumption and less environmental impact in transportation.
  • Installation Efficiency. Plastic pipes are known for their ease of installation. Faster installation translates to lower energy consumption and emissions associated with construction activities.
  • Water and Energy Conservation. Plastic pipes offer better insulation compared to metal alternatives like copper, contributing to energy efficiency in the long run.

Looking after your multilayer pipe system

Despite being highly durable, like any plumbing and heating installation, the STH Westco Multilayer Pipe System still requires a degree of care and maintenance. Our technical experts recommend following these top tips when installing, troubleshooting, and maintaining the system:

  • Follow manufacturer guidelines for proper installation, maintenance, and repairs
  • Protect the plastic pipes from sudden pressure surges by installing pressure-reducing valves or water hammer arrestors
  • Provide adequate support for plastic pipes, especially if they are used for horizontal runs
  • Ensure proper tightening of connectors
  • Use tools designed for the material to avoid damaging the pipes or fittings
  • Avoid excessive force during installations or repairs
  • Store the plastic pipes in a cool, dry place away from direct sunlight
  • Consider installing a water softener in hard water areas/install water filters if water quality is a concern
  • Insulate pipes in areas prone to freezing
  • Periodically inspect the plumbing system for any signs of leaks, cracks, or damage, and address any issues promptly
  • Avoid harsh chemicals, solvents, or drain cleaners that can damage plastic pipes over time
  • Maintain a clean, debris-free area around the pipes
  • Regularly flush the system to remove sediment and debris.
