Copper vs. PVC Pipe Fittings: Which Works Best for Plumbing in Singapore?

Plumbing keeps homes and buildings running smoothly. Picking the right pipe fittings helps prevent leaks, cut costs, and keep water flowing safely. In Singapore, copper pipe fittings and PVC pipe & fitting are the top water system choices.

Each material brings different strengths and weaknesses. Knowing how they compare helps homeowners and workers choose wisely. This guide outlines the key differences to help you pick the best plumbing option.

1. Why Do People Choose Copper Pipe Fittings?

For many years, plumbers have trusted copper pipes. These pipes fight rust, hold firm under pressure, and handle both hot and cold water without cracking.

Why Pick Copper Pipe Fitting?

• Lasts for Decades – Copper stays tough for over 50 years without breaking.

• Handles Heat Well – Boiling water won’t bend or weaken it.

• Blocks Rust – Copper shields itself from corrosion and harsh chemicals.

• Keeps Water Clean – Copper stops bacteria from growing, keeping drinking water safe.

• Holds Firm Under Pressure – Copper won’t burst even when water rushes through.

• Resists Fire Damage – Unlike plastic pipes, copper won’t burn or release toxic smoke during a fire.

• Prevents Contamination – Copper doesn’t soak up harmful chemicals from nearby materials.

Why Avoid Copper Pipe Fitting?

• Costs More – Copper pulls more money from your budget than PVC due to high material and labour costs.

• Needs Skilled Hands – Soldering demands special tools and trained workers.

• May Attract Thieves – Copper sells for a high price, making it a target for theft.

• Weighs More – Copper feels heavier than PVC, making transport and setup harder.

2. Why Do People Choose PVC Pipe & Fitting?

PVC (Polyvinyl Chloride) provides a lightweight, low-cost plumbing option. It works best for drainage, waste systems, and cold-water plumbing.

Why Pick PVC Pipe & Fitting?

• Saves Money – PVC costs less than copper, shrinking material and labour expenses.

• Easy to Install – PVC clicks together with glue and simple fittings, skipping welding and special tools.

• Blocks Rust – PVC won’t corrode or react with chemicals.

• Light and Easy to Move – PVC weighs much less than copper, making it easy to carry and install.

• Great for Drainage – PVC works well for waste pipes and rainwater drains.

• Bends Easily – PVC twists and flexes more than copper, making it useful for tight spaces.

• Perfect for DIY Projects – Homeowners can set up PVC pipes without professional help.

Why Avoid PVC Pipe & Fitting?

• Melts in High Heat – PVC softens and bends when hit with boiling water.

• Cracks Under Heavy Pressure – Strong water flow can break PVC over time.

• Wears Out Faster – PVC does not last as long as copper.

• May Leak Chemicals – Some PVC pipes release harmful substances into drinking water.

• Burns Easily – PVC melts in extreme heat and gives off toxic fumes when burned.
