CPVC vs. UPVC: Choosing the Right Pipe for Your Home
The Battle of the Polymers
While both are corrosion-resistant, using the wrong one in a hot water line can lead to structural failure.
Key Differences:
- CPVC: Ideal for both hot and cold water. Can withstand temperatures up to 93°C; mandatory for geysers.
- UPVC: Best for cold water supply and drainage. It is more rigid and cost-effective but brittle under high heat.
- Flexibility: CPVC is easier to install in the tight, complex layouts of Mumbai apartments.
Frequently Asked Questions (FAQ)
No. UPVC will warp and burst under heat. Always use CPVC for hot water lines.
Both resist salt-air corrosion, but CPVC is more robust for internal residential pressure.
