Know About Features of Copper Pipes and CPVC Pipes

There are several key differences between CPVC pipe & CPVC pipes, copper pipes and other types of piping. We’ll discuss the major differences between them and the benefits of each.

The Main Types of Pipes

The earliest drain pipes were made of cast iron, lead, bronze or galvanized iron. These materials were used because they were so easily shaped. These types of pipe have been replaced by plastic pipes. The two main types of plastic pipe are PVC and CPVC. PVC stands for polyvinyl chloride. CPVC is short for chlorinated polyvinyl chloride.

PVC pipe is regularly used in drainage systems, cold water supplies and vents. CPVC is more often used for hot water pipes. But why are PVC and CPVC pipes used so much more often than the alternatives they’ve replaced?

Lack of Corrosion

Any metal pipe is prone to corrosion. This most often takes the form of rust, though oxidation will hit copper pipes, too. Corrosion will lead to leaks. This requires costly repairs or replacement of the pipes. Corrosion also creates the possibility the drinking water will become contaminated, while wastewater could leak into your walls or soil, contaminating that. Plastic pipes resist corrosion, so it prevents this contamination. Another benefit of CPVC and PVC pipes is that its smooth surface resists deposition and scaling. For example, the trace minerals in drinking water like calcium are less likely to deposit on the interior of the pipe. When these mineral layers build up, you lose water pressure until the pipe is clogged. At any time, large pieces of the scale can break up and clog your pipes. Plastic pipes thus ensure smooth, constant drainage.

Easy Transportation and Installation

Traditional pipes made from ceramics or metal were heavy. This made them difficult to transport and hard to install. Having to weld them together added to installation costs, and every weld joint is subject to corrosion. Plastic pipes, in contrast, are lightweight. They’re easy to install thanks to their design. They may be screwed together or they can be snapped together, a layer of epoxy used for extra security.

Damage Resistance

Ceramic pipes were particularly prone to damage. They could break during transport and installation. They’re also prone to shifting and cracking along with your foundation. Plastic pipes can’t be damaged when handled, and they rarely crack when the structure of your home is damaged.

Resistance to Changes in Climate

Suppose the heat goes out in your house. An older home with lead, copper or steel pipes is going to have the water inside those pipes freeze faster than if they were in PVC or CPVC pipes. Plastic pipes are less prone to bursting in cold weather.

Their thick walls also acts as an insulator, so the hot water sent across the house remains warm when carried by PVC pipes relative to copper pipes. A side benefit of this low thermal conductivity is that plastic pipes are less prone to “sweating”, where condensate in the air condenses on the pipes. These drops of water can flow down the pipes and create puddles in the bottom of your walls. That will eventually erode the wood in

the walls and fuel mold growth.


Plastic pipes are cheaper than metal pipes when you first buy them. Installation costs are often lower, as well.

The Option of Geocomposite Pipes

Geocomposite pipes are made from a combination of nets, membranes and textiles. This mix of materials helps the pipe perform several tasks at once. The textiles filter the material passing through the pipe, capturing solids like soil particles. Liquids and gasses pass through. These pipes are relatively light and low cost. They are generally used in drainage pipes under landfills, basements, highways and retaining walls. Geocomposite pipes are typically the better choice for utility projects, while PVC and CPVC pipes are better for most residential and commercial projects.
