A practical guide from the team at Puranmal Sons & Ceramix Syndicate.
Use CPVC for hot and cold water plumbing inside buildings, and UPVC for cold water supply, agriculture and column pipes. Both are corrosion-free and long-lasting, but they handle heat very differently, which is the main thing that decides your choice.
CPVC (chlorinated polyvinyl chloride) is designed to carry hot water safely — typically up to around 93°C. That makes it the standard choice for internal plumbing where hot and cold lines run together, such as bathrooms and kitchens.
UPVC (unplasticised PVC) is a rigid pipe for cold water only. It's widely used for cold water supply lines, borewell column pipes and agricultural applications. It should not be used for hot water.
Ask three questions: Will the line carry hot water? (If yes, CPVC.) Is it an internal plumbing line or an external/cold supply line? What pressure and diameter does the application need? If you share your layout or BOQ, our team will specify the right system, sizes and fittings for you.
Share your list or BOQ and we'll call back with pricing and availability, usually the same working day.
