Plastic Pipes, Are They Right For You?

Homeowners and plumbers have plenty of choices when it comes to the piping to use for plumbing systems. Copper and PVC piping are two of the most popular types of piping available on the market, and are worked with frequently by the professionals at CW Service Pros . Since it conducts heat and electricity well, copper is usually the leading choice for water piping. However, plenty of homeowners are opting for plastic pipes as a cheaper and more durable alternative to copper. The following takes a look into the many pros and cons plastic piping has over similar copper and cast-iron pipes. Afterwards, homeowners can decide for themselves whether to take advantage of plastic piping, or stick to the more traditional copper and cast-iron piping for their home.

What is Plastic Piping?

Plastic piping, also known as Polyvinyl Chloride or PVC pipe, is made from a durable vinyl polymer that makes it suitable for many plumbing tasks. Plastic piping is often noted for its ease of installation, since there aren’t any special tools required outside of the solvent used to bond pipes and joints together. Plastic piping enjoys extensive use in countless construction projects thanks to its durability and ease of assembly. It also enjoys plenty of use in industrial applications where the cost of copper or cast-iron piping is prohibitive when compared with similar PVC piping.

Advantages

Plastic piping offers a significant price advantage over similar copper piping. Unlike copper, plastic piping is cheaper to produce, purchase and install. They are also resistant to corrosion and abrasion, making them viable for long-term use. These pipes also tend to be quieter than copper pipes, even at higher water velocities. Homeowners who complain about the metallic taste of water run through copper piping will enjoy plastic piping as an alternative.

Disadvantages

While plastic pipes are less prone to corrosion and abrasion, they are more delicate during installation. Unlike copper, which can be bent back into shape if stepped on, PVC piping will crack or even shatter. The solvents used to join pipes and fittings require plenty of ventilation during the installation process. Compared to the metallic taste of water that is run through copper pipe, some homeowners complain about a plastic taste in their water. Plastic piping also has the tendency to support bacterial growth under the right conditions. Ordinary PVC piping can become toxic when exposed to heat, making them completely unsuitable for use as hot water pipes and other similar applications. However, chlorinated polyvinyl chloride (CPVC) is safe for transporting hot water. Cost considerations and ease of installation are the biggest reasons homeowners choose plastic piping over copper for modern home improvement projects, especially for most do-it-yourself projects. Both copper and plastic piping offer similar advantages and disadvantages to one another – it is ultimately up to the homeowner to decide which type of plumbing they want to have in their home.

FAQs

Are all plastic plumbing pipes made from PVC?

No. PVC, CPVC, and PEX are different materials with different applications and installation methods. Choosing “plastic pipe” is only the starting point; the exact product must suit the job.

Can plastic pipes carry hot water?

Certain CPVC and PEX systems are designed for hot- and cold-water distribution. Check the specific product’s temperature and pressure ratings rather than assuming every plastic pipe is suitable.

Are plastic pipes suitable for drinking water?

Products designed and certified for potable-water service can be suitable when installed correctly. Check the exact pipe, fittings, and relevant certification. NSF/ANSI/CAN 61 addresses health effects associated with drinking-water system components.

Are plastic plumbing pipes always cheaper than copper?

No single price comparison applies to every project. Material costs, fittings, labor, access, and the amount of restoration required all affect the final estimate. Compare quotes for the same scope of work.

Can I replace copper pipes with plastic piping?

It may be possible, but the replacement material and transition fittings must suit the application. A plumber should assess the existing system, proposed layout, operating conditions, and installation requirements before recommending a change.

How do I decide whether my home needs repiping?

Pipe material alone does not establish a need for replacement. Recurring leaks, documented deterioration, and other persistent problems warrant assessment. Ask whether a targeted repair or broader replacement best addresses the diagnosed condition.

Choose the Material That Fits the Application

Plastic plumbing pipes can be a practical option, but PVC, CPVC, and PEX serve different purposes. The right choice depends on what the pipe carries, its operating conditions, and the requirements of the installation. Before repairing or replacing piping, compare suitable systems and have the existing plumbing assessed.
