Types of Plumbing Pipes Used in Indian Homes: CPVC vs UPVC vs PVC vs GI

### Choosing the Right Pipe for Every Application

Using the wrong pipe type can lead to premature softening, cracking, or toxic leaching. Here is a breakdown of modern pipe standards in India:

- **CPVC (Chlorinated Polyvinyl Chloride):** The gold standard for domestic indoor plumbing. Can handle hot water up to 93°C and cold water under high pressure without scale buildup. - **UPVC (Unplasticized Polyvinyl Chloride):** Ideal for cold water distribution and outdoor supply lines. UV-stabilized, rigid, and lead-free. - **PVC / SWR (Soil, Waste & Rainwater):** Lightweight, chemical-resistant pipes with rubber ring joints specifically designed for drain and sewer applications. - **GI (Galvanized Iron):** Historically popular, but largely phased out due to internal rust, lime scale choking, and heavy weight.
