Types of Plumbing Pipes and Their Uses

Every plumbing system has a job to do. One line brings clean water to your kitchen tap. Another carries hot water from the geyser to the shower. A third takes wastewater safely away from the house. Each of these lines needs a different kind of pipe.

That is why understanding the different types of pipes used in plumbing makes such a difference, whether you are building a home, renovating a bathroom or planning a commercial project. In this guide, we break down the most common plumbing pipes, what they are made of, and exactly where each one fits.

How Plumbing Pipes Are Grouped

Before going into each type, it helps to know that plumbing pipes are usually grouped by the job they do:

• Water supply lines: Carry clean, pressurised water for drinking, cooking and bathing
• Drainage and waste lines: Carry soil, wastewater and rainwater away by gravity
• Underground and service lines: Bring water from the main supply to the building
• Borewell lines: Line the borewell and lift groundwater from the pump to the surface

The material you choose depends on water temperature, pressure, whether the pipe is indoors or underground, and whether it carries drinking water or waste.

Common Plumbing Pipe Types Explained

1. CPVC Pipes

CPVC (Chlorinated Polyvinyl Chloride) pipes are made by chlorinating PVC resin, which gives them much higher heat resistance than standard PVC.

CPVC pipe uses:

• Hot and cold water supply in homes, apartments and villas
• Bathroom and kitchen lines connected to geysers and water heaters
• Water distribution in hotels, hospitals, schools and offices
• Selected industrial lines that carry chemicals or salt water

Why it works: CPVC handles high service temperatures, does not rust, resists scaling and uses leak-proof solvent cement joints. Utkarsh CPVC pipes and fittings are made to IS 15778 and ASTM D2846 standards.

2. uPVC Pipes

uPVC (unplasticised Polyvinyl Chloride) pipes are rigid, lightweight and cost-effective. They are one of the most widely used pipes for cold water.

PVC pipe uses:

• Cold water plumbing lines inside and outside buildings
• Overhead tank to tap connections
• Cold water distribution in residential and commercial buildings

Why it works: uPVC is corrosion-free, easy to cut and join, and keeps water clean.

3. SWR Pipes

SWR pipes stand for Soil, Waste and Rainwater. These pipes are designed for drainage, not water supply.

Uses:

• Toilet and bathroom soil lines
• Kitchen and washbasin waste lines
• Rainwater downpipes from roofs and terraces
• Vent pipes in drainage systems

Why it works: SWR pipes have a smooth inner surface that helps waste flow freely. They also resist household chemicals and are easy to join with ring-fit or solvent-fit joints.

4. HDPE Pipes

HDPE (High Density Polyethylene) pipes are flexible, tough and highly resistant to impact and ground movement.

Uses:

• Underground water supply lines from the main to the building
• Municipal water mains and long-distance water transport
• Service connections in housing societies and townships

Why it works: HDPE can bend with the ground, handles pressure well and has very few joints over long runs, which lowers leak risk.

5. Borewell Pipes: Casing and Column Riser Pipes

Homes and buildings that depend on groundwater need a separate set of pipes.

• PVC casing pipes line the borewell and protect it from collapse and contamination.
• uPVC column riser pipes connect the submersible pump to the surface and carry water up to the storage tank.

Why it works: Casing pipes keep the borewell walls stable and the water free from soil and debris, while uPVC column pipes are lightweight, rust-free and easy to lower or lift during pump maintenance.

6. Other Pipe Materials

You may also come across copper pipes, which are durable and heat resistant but expensive, and PPR pipes, which are joined by heat fusion and used for hot and cold water in some projects. Both are less common in everyday Indian home plumbing than CPVC and uPVC.

Frequently Asked Questions

What are the different types of pipes used in plumbing?

The main types are CPVC, uPVC, SWR, HDPE, GI, copper and PPR pipes. CPVC and uPVC are used for water supply, SWR for drainage, HDPE for underground lines, and casing and column pipes for borewells.

What are CPVC pipes used for?

CPVC pipes are used for hot and cold water supply in homes, apartments, hotels, hospitals and offices. They are ideal for lines connected to geysers and water heaters.

What are PVC pipes used for?

uPVC pipes are used for cold water supply lines and overhead tank connections. Other PVC pipes, such as SWR, casing and column pipes, are used for drainage and borewell systems.

Is GI pipe better than plastic pipe for home plumbing?

For most homes, plastic pipes such as CPVC and uPVC are the better choice. They do not rust, resist scaling, are lighter and are easier to install than GI pipes.

Which pipe is used for drainage in houses?

SWR (Soil, Waste and Rainwater) pipes are used for toilet, bathroom, kitchen and rainwater drainage in houses.

Can I use uPVC pipes for hot water?

No. uPVC pipes are designed for cold water only. For hot water lines, use CPVC pipes.
