Which pipe is better CPVC or PVC?
The better pipe, CPVC or PVC, depends on the application. Here’s a breakdown of their key differences to help you choose:
Temperature Resistance:
- CPVC: Winner here. CPVC can handle higher temperatures, up to 200°F (93°C).
- PVC: Maxes out at 140°F (60°C).
Applications:
- CPVC: Ideal for hot water lines, as well as cold water lines. Can also be used in some industrial applications involving chemicals.
- PVC: Best for cold water lines, drain lines, vent lines, and some non-pressurized applications like sprinkler systems.
Other Considerations:
- Strength: Both CPVC and PVC are strong and durable, with CPVC having a slight edge in tensile strength.
- Flexibility: CPVC offers a bit more flexibility than PVC.
- Cost: CPVC is generally more expensive than PVC.
Here’s a table summarizing the key points:
| Feature | CPVC | PVC |
|---|---|---|
| Temperature Resistance | Up to 200°F (93°C) | Up to 140°F (60°C) |
| Best Uses | Hot water lines, cold water lines, some chemical applications | Cold water lines, drain lines, vent lines, non-pressurized applications |
| Flexibility | More flexible | Less flexible |
| Cost | More expensive | Less expensive |
In conclusion:
- Choose CPVC for hot water lines or if higher temperature resistance is needed.
- Choose PVC for cold water lines, drain lines, vent lines, or cost-sensitive applications where temperature is not a major concern.
Remember: Always check local building codes for any specific requirements regarding pipe materials for your project. Consulting with a plumber can also be helpful for getting expert advice on the best pipe for your particular needs.
