While plastic pipe systems are now readily accepted as a viable alternative to traditional metal materials, there are still many in the building services industry that are mistaken about the performance capabilities of plastic pipe products.
At HP Mechanical, we pride ourselves on using the correct materials for each and every job for our clients throughout Sonoma County. So, here are some facts and fables about plastic pipe systems.
One of the most common misconceptions is that all plastic pipe systems are the same and there is an assumption that the characteristics of one material will be the same with other plastic materials. However, every plastic material has different performance capabilities and has been specially designed for specific applications.
Fact: The mistake is often made of comparing initial material costs, but when looking at the installed costs of a system, plastics offer significant cost savings. The lightweight nature of plastic pipe systems, combined with their quick and simple jointing methods, significantly reduces the installation labor time and costs, offering installed cost savings of up to 50% compared with steel or copper systems.
Fact: Plastic pipe systems require less maintenance than traditional materials, such as copper and steel. Corrosion is the biggest cause of maintenance and replacement costs in metal systems, with unseen corrosion in copper and steel HVAC systems having the potential to cause severe damage and significantly impact on operational efficiency. As a result, metal pipe systems need to be continually monitored, with regular flushing of the system scheduled, alongside taking frequent water samples to ensure the water quality is not adversely affected by any corrosion. With plastic pipe systems completely corrosion resistant this is not an issue, eradicating associated maintenance and repair time and costs.
In addition, the smooth bore of plastic pipe systems ensures no lime scale can build up within the system, resulting in less friction loss and guaranteeing a consistent flow rate is maintained throughout the life of the system. With optimum flow levels maintained, minimal maintenance and repair work is required to ensure the system operates efficiently.
Fact: Plastic pipe systems have a 50-year design life, with the operational performance remaining at the same level throughout the lifetime of the system. The smooth bore of plastic pipe resists lime scale build-up, ensuring flow is not restricted and continues at the same rate throughout its working life.
Fact: While it is widely acknowledged that plastic materials expand and contract more when compared with metals, thermal expansion in plastic pipes can be easily catered for if addressed at the design stage of a project.
The simplest and most cost effective method of catering for thermal movement is to use the natural flexibility of the pipe system by building in changes of direction to the network design. The direction of pipe movement can be controlled by the use of anchor points at strategic positions. Other cost effective solutions include installing expansion loops, bellows, flexible hoses and expansion compensators.

Rudy did excellent work and I’m happy to recommend him and hire him again. He installed a new water heater to code, was responsive, on time and kept the job site tidy, and charged a fair price.
Also appreciated his readiness to answer questions and provide guidance.
