When it comes to plumbing, choosing the right type of pipe can be overwhelming. With so many options available, it’s important to understand the differences between them to make an informed decision. Two popular types of pipes are CPVC and PVC. In this article, we’ll compare CPVC vs PVC pipe and help you determine which one is better for your plumbing needs.

Are PVC And CPVC The Same?
Although PVC (polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride) are both made from the same base material, they are not the same. CPVC undergoes an additional chlorination process, which makes it capable of withstanding higher temperatures than regular PVC.
In fact, approximately 40 percent of the bonding sites on the backbone of CPVC are filled with chlorine atoms, which give it its unique properties.
CPVC is known for its heat-resistance and ability to withstand higher temperatures than PVC. It is often used as an alternative to copper or galvanized pipes because it is resistant to corrosion from certain substances such as corrosive soil acids and salt.
On the other hand, PVC is often used for drain lines because it is cheap and does not rust.
Due to their differing properties, PVC and CPVC have different applications and are not typically used in the same types of situations. PVC is commonly used in low-temperature applications, while CPVC is used in high-temperature applications
Are PVC And CPVC Glue The Same?
PVC and CPVC glues are not the same. These two types of plastic require different glues for a reliable fit. While CPVC glue technically can be used on PVC piping.
it’s recommended to use the appropriate PVC solvent cement and primer for the specific application. Conversely, you cannot use PVC glue on CPVC pipe.
The PVC cement process is actually a two-step solvent welding process, while cementing CPVC is a contact cement.
This means that the PVC primer cleans and initially softens the PVC, while the CPVC primer acts as a simple contact adhesive.
There is no such thing as a “CPVC to PVC glue,” so chemically joining CPVC and PVC requires solvent cement and primer that are strong enough to fully bond the materials.
Differences Between CPVC and PVC Glue
CPVC and PVC glues are different and require specific adhesives for a secure fit. CPVC glue is a contact cement that chemically fuses the pipe and fitting together, making it stronger and more durable than PVC glue.
While CPVC glue can technically work on PVC piping, it is recommended to use the appropriate PVC solvent cement and primer for the job.
The PVC cement process is a two-step solvent welding process, while CPVC cementing is a contact cement.
The primer cleans and softens the PVC, while there is no special “CPVC to PVC glue” available, so using solvent cement and primer strong enough to fully bond the materials is necessary for joining CPVC and PVC.
Can you use CPVC glue on PVC pipes
Yes, it is possible to use CPVC glue on PVC pipes. However, it is important to note that PVC and CPVC have different applications, and are not typically used in the same types of systems.
PVC is commonly used in drain lines, while CPVC is more suitable for water supply lines due to its ability to withstand high temperatures better than PVC.
Using CPVC glue on PVC pipes requires careful consideration of the adhesive, fittings, and procedures involved. CPVC glue is a contact cement that chemically fuses the pipe and fitting together, creating a strong and reliable seam.
Although it is recommended to use the correct adhesive whenever possible, CPVC glue can be a viable option for connecting PVC pipes if done correctly.
CPVC Vs. PVC Glue: Which One Should I Use?
To ensure a secure and effective bond between pipes, it’s important to use the appropriate glue for the specific type of pipe. For PVC pipes, it’s recommended to use PVC glue, and for CPVC pipes, CPVC glue is the way to go.
Although there may be some flexibility when using CPVC glue on PVC pipes, it’s still best to use the proper glue for the pipe to ensure optimal bonding.
Using the wrong type of glue can result in weakened joints and potential leaks, which can lead to costly repairs or even system failure.
Therefore, it’s essential to follow the manufacturer’s instructions and use the recommended glue for each type of pipe.
