What's the Difference Between PVC and CPVC Pipe? -2

Applications of PVC & CPVC:

As mentioned before, CPVC is more suitable for hot water applications up to 200F. PVC is still often used for unheated water as well as for vent and drainage systems; however, CPVC has become widely used for both hot and cold potable water.

The more resistant properties of CPVC make it useful for commercial and industrial applications as well. Because of its wider range of applications, CPVC is usually pricier than PVC. That being said, it is still a very cost-effective and versatile material.

We recommend the use of PVC for recreational use/building, cold water systems, vent systems, and drainage systems. CPVC is recommended for applications where the maximum temperature will exceed 140 degrees Fahrenheit, but stay under CPVC's max rating of 200 degrees Fahrenheit.

Another deciding factor in which material to use is the chemical makeup of media being handled in your application. Though PVC and CPVC both are resistant to many of the same chemicals, some are best handled by one or the other.

Can PVC & CPVC be used together?

All NPS size pipe and fittings will fit together, but it is not recommended that you mix and match materials. Mixing materials can compromise the pipe line's temperature and pressure ratings. For that reason we always recommend any pressurized pipe system be constructed using matching piping material and schedules.
