Choosing the Right Plumbing Pipes: CPVC vs UPVC vs PVC

The Hidden Danger of Cheap Plumbing

Plumbing pipes are embedded deep within your brickwork and concrete. A single leak can cause massive structural dampness and require breaking expensive tiles to repair. Choosing the correct polymer pipe is critical.

1. CPVC (Chlorinated Polyvinyl Chloride)

CPVC is the premium choice for modern indoor plumbing, characterized by its creamish-yellow color.

• Best For: Both HOT and COLD water supply lines.
• Pros: Can withstand temperatures up to 93°C (200°F), highly durable, scaling resistant, fire retardant.
• Cons: More expensive than UPVC and PVC.
• Top Brands: Ashirvad, Supreme, Astral.

2. UPVC (Unplasticized Polyvinyl Chloride)

UPVC is a rigid, strong plastic pipe usually white in color.

• Best For: COLD water supply only.
• Pros: Very strong, lead-free, cost-effective, UV resistant (suitable for exposed outdoor lines).
• Cons: Cannot handle hot water (will warp and burst).

3. SWR PVC (Soil, Waste, and Rainwater)

These are the large, grey pipes used for drainage.

• Best For: Drainage, sewage, and rainwater harvesting.
• Pros: Large diameter, smooth inner surface prevents clogging, highly chemical resistant.
• Cons: Not suitable for pressurized water supply.
