Pipe lines for the house construction

Building a house is not only about bricks, cement, and design. A strong and safe house also needs the right pipeline system. Pipelines are like the veins of a house. They carry water, gas, and waste. If you choose the wrong pipe, you may face leakage, damage, or safety problems.

In this blog, we will explain:

• Which pipe is best for water supply (hot and cold)

• Which pipe is best for gas lines

• Which pipe is best for sewerage and drainage

• Top 5 companies in Pakistan that provide these pipes

This guide will help you make the right decision for your home.

1. Water Supply Pipes in House (PPRC Pipes)

For water supply, both hot and cold, the most common and best choice in Pakistan is PPRC pipes.

What is PPRC?

• PPRC stands for Polypropylene Random Copolymer.

• It is a special type of plastic pipe designed to carry water.

• These pipes are strong, safe for drinking water, and can handle both hot and cold temperatures. pipe lines for the house construction

Why use PPRC for water?

1. Hot and Cold Friendly – Can carry both hot water (from geyser) and cold water without damage.

2. Rust Free – Unlike steel pipes, these pipes never rust.

3. Leakage Free Joints – Heat fusion welding makes strong joints.

4. Safe for Health – No harmful chemicals in drinking water.

5. Long Life – Can last 40–50 years if installed properly.

Common Uses

• Kitchen and bathroom water supply

• Geyser hot water line

• Overhead tank to house distribution line

2. Gas Supply Pipes (GI or MDPE Pipes)

For gas pipelines, GI (Galvanized Iron) pipes or MDPE (Medium Density Polyethylene) pipes are used.

Galvanized Iron (GI) Pipes

• Strong metal pipes with zinc coating to prevent rust.

• Commonly used inside the house for gas pipelines.

• Can handle gas pressure safely.

• Require skilled welder/fitter for installation.

MDPE Pipes pipe lines for the house construction

• Full form: Medium Density Polyethylene.

• Yellow color pipe used for underground gas lines by SNGPL.

• Flexible, rust-free, and long life (more than 50 years).

• Mostly used from main gas supply to the house boundary.

Why GI or MDPE for gas?

• Gas is dangerous. Wrong pipes can leak and cause fire.

• GI and MDPE are approved by gas companies in Pakistan.

• They are strong, safe, and long-lasting.

IL (Galvanized Iron Line) Pipes vs MDPE Pipes

When we compare IL (Galvanized Iron Line) pipes with MDPE pipes, there are two important things to note:

1. Cost – IL pipes are cheaper than MDPE pipes. For this reason, many homeowners in Pakistan prefer IL pipes inside the house, because they are affordable and easily available.

2. Recommendation for House Use – For underground main gas line (from the street to the house), SNGPL usually prefers MDPE pipes. But for inside the house construction, IL pipes are recommended because:

   • They are cost-effective pipe lines for the house construction

   • Strong enough to handle household gas pressure

   • Easily available in every city

   • Gas fitters and welders are more skilled in working with IL pipes

Conclusion:

• Use MDPE for underground gas supply (from Sui Gas connection to your home boundary).

• Use IL pipes inside your house for gas lines, because they are cheaper and reliable.

3. Sewerage and Drainage Pipes (UPVC Pipes)

For waste water and sewerage, the best option is UPVC (Unplasticized Polyvinyl Chloride) pipes.

What is UPVC?

• A type of plastic pipe, very strong and rigid.

• Designed to carry dirty water, rain water, and sewage.

Why use UPVC?

1. Rust Free – Unlike iron, it never rusts.

2. Smooth Flow – Inside surface is smooth, so no blockage easily.

3. Lightweight – Easy to install and handle.

4. Durable – Long life, can stay strong for decades.

5. Economical – Cheaper than metal pipes.

Common Uses

• Kitchen and bathroom drainage

• Toilet sewerage

• Rain water pipes

• Main sewer connection to street

4. Which Pipe Where? (Quick Guide)

• PPRC – Best for clean water (hot and cold).

• GI / MDPE – Best for gas supply (inside = GI, outside = MDPE).

• UPVC – Best for sewerage and drainage.
