Are you thinking of tackling a home plumbing project entirely on your own? Maybe you just want to understand what your plumber is trying to explain to you about the differences in the types of pipes they are offering. No matter what your reason is, every homeowner should know the difference between CPVC and PVC pipes. 


Learn more about these two different types of pipes and how they differ in this detailed guide. 


The Major Difference

The most significant difference between PVC and CPVC pipes is the temperature that they can withstand before the pipes begin to soften and the joints begin to fail. If you exceed the maximum temperatures of these pipes, you will find that your plumbing will fail. This is why it is so important to know just how you plan to use your pipes before moving forward. 


There is quite a difference in what each type of pipe can handle temperature-wise. CPVC tolerates heat up to 93℃ (200℉) while PVC can only tolerate temperatures up to 60℃ (140℉). It might not seem like much, but that can make a world of difference when it comes to how well your plumbing will hold up in the long run. 


Minor Differences

These two types of pipes will be made from different materials which is why one is more tolerant of heat than the other. As a result of this difference in manufacturing, you will find that several other factors are affected as well. For example, you will need to use primers and bonding agents that are specific to either PVC or CPVC pipes. 


Another difference between these two types of pipes is the size that they come in. You will have no trouble finding PVC pipes in nominal pipe sizes, but CPVC is a bit different. It comes in both nominal pipe sizes and copper tube sizes. 


Support is another factor you should consider when deciding what type of pipe is right for your project. CPVC tends to be a bit more flexible and will require more support. Most experts uphold the standard of placing a support every three feet along the path. 


CPVC is also manufactured with more chlorine in its makeup than regular PVC. This means that it is chemically stronger and prevents the buildup of bacteria inside your pipes. However, both of these types of pipes will be durable when used under the right conditions.
