Common Plumbing Pipes - Their Pros & Cons

Understanding the different types of plumbing pipes used in residential and commercial properties is crucial for both property owners and professionals in the industry. Here, we will explore the most common plumbing pipes, their benefits, and potential drawbacks, to help you make informed decisions regarding your plumbing system. At Sewer Surgeon, we have extensive experience dealing with various types of plumbing pipes and are dedicated to providing expert advice and services.

PVC Pipes

Polyvinyl chloride (PVC) pipes are among the most popular choices for plumbing systems. They are commonly used for drain, waste, and vent piping.

Pros of PVC Pipes:

• Durability: PVC pipes are resistant to corrosion and chemical damage, making them long-lasting.
• Cost-Effective: These plumbing pipes are relatively inexpensive compared to other types.
• Lightweight: PVC pipes are easy to handle and install due to their lightweight nature.
• Non-Toxic: They do not leach harmful chemicals into the water supply, ensuring safety.

Cons of PVC Pipes:

• Temperature Limitations: PVC plumbing pipes can become brittle and crack in extreme temperatures, particularly in freezing conditions.
• Pressure Sensitivity: They are not suitable for high-pressure applications.
• Not Suitable for Hot Water: PVC cannot withstand high temperatures, limiting its use to cold water systems only.

Copper Pipes

Copper pipes have been a staple in plumbing for decades, renowned for their reliability and longevity.

Pros of Copper Pipes:

• Durability: Copper plumbing pipes are highly durable and resistant to corrosion.
• Temperature Resistance: They can handle both hot and cold water without deforming.
• Bacteria-Resistant: Copper is naturally resistant to bacterial growth, ensuring a clean water supply.
• Recyclable: Copper pipes are environmentally friendly as they can be recycled.

Cons of Copper Pipes:

• Cost: Copper is one of the more expensive piping materials.
• Installation Difficulty: These plumbing pipes require soldering, making installation more complex.
• Potential for Theft: Due to their value, copper pipes can be a target for theft.

PEX Pipes

Cross-linked polyethylene (PEX) pipes are a newer innovation, offering flexibility and ease of installation.

Pros of PEX Pipes:

• Flexibility: PEX plumbing pipes can bend around corners, reducing the need for fittings and making installation easier.
• Temperature Resilience: They can withstand both hot and cold water applications.
• Cost-Effective: PEX is generally less expensive than copper.
• Quick Installation: The installation process is quicker and simpler compared to rigid plumbing pipes.

Cons of PEX Pipes:

• UV Sensitivity: PEX pipes can degrade if exposed to sunlight, limiting their use to indoor applications.
• Chemical Sensitivity: They may react with certain chemicals, potentially affecting water quality.
• Not Recyclable: Unlike copper, PEX plumbing pipes are not recyclable, which can be a concern for environmentally conscious individuals.

Galvanised Steel Pipes

Once widely used, galvanised steel pipes are now less common due to their tendency to corrode over time.

Pros of Galvanised Steel Pipes:

• Strength: These plumbing pipes are strong and can handle high pressures.
• Durability: They have a decent lifespan when not exposed to corrosive elements.
• Availability: Galvanised steel pipes are readily available and have been used in plumbing for many years.

Cons of Galvanised Steel Pipes:

• Corrosion: Over time, galvanised plumbing pipes can corrode, leading to rust and reduced water quality.
• Weight: They are heavy and difficult to work with, making installation labour-intensive.
• Reduced Diameter: Corrosion can cause the internal diameter to decrease, affecting water flow.

Cast Iron Pipes

Cast iron pipes are commonly found in older homes and are known for their robustness and noise-dampening qualities.

Pros of Cast Iron Pipes:

• Durability: Cast iron plumbing pipes are extremely durable and can last for decades.
• Noise Reduction: They are excellent at reducing the noise of running water.
• Fire Resistance: Cast iron is non-combustible, adding a layer of safety.

Cons of Cast Iron Pipes:

• Weight: They are very heavy, making installation and repairs more difficult.
• Corrosion: Cast iron can rust over time, leading to potential leaks and blockages.
• Cost: They are more expensive compared to modern materials like PVC and PEX.

Concrete Pipes

Concrete pipes are primarily used in sewer systems and drainage applications due to their strength and durability.

Pros of Concrete Pipes:

• Strength: Concrete plumbing pipes are incredibly strong and can handle large volumes of water.
• Durability: They are resistant to most forms of damage, including corrosion and abrasion.
• Longevity: Concrete pipes have a very long lifespan, often exceeding 50 years.

Cons of Concrete Pipes:

• Weight: Like cast iron, concrete plumbing pipes are heavy and challenging to install.
• Cost: They can be expensive due to the material and the labour required for installation.
• Cracking: Over time, concrete can crack, especially if exposed to significant pressure changes.

Frequently Asked Questions

What is the best type of plumbing pipe for high-pressure applications?

The best type of plumbing pipe for high-pressure applications is usually copper. Copper pipes are known for their strength and durability, making them ideal for handling high water pressure without leaking or bursting. They are also resistant to corrosion and can last for decades with proper maintenance.

Can PEX pipes be used for both hot and cold water?

Yes, PEX pipes can be used for both hot and cold water. They are highly flexible, resistant to scale and chlorine, and can handle high temperatures. PEX pipes are often colour-coded, with red for hot water and blue for cold water, to make installation easier.

Are PVC pipes suitable for outdoor use?

While PVC pipes are durable and resistant to corrosion, they are not recommended for outdoor use in direct sunlight. UV rays can degrade the material over time, making it brittle. However, if properly shielded or buried, PVC can be a good choice for outdoor plumbing.

How do I know if my galvanised steel pipes need replacing?

Galvanised steel pipes may need replacing if you notice rust-coloured water, low water pressure, or frequent leaks. These pipes are prone to corrosion over time, which can lead to clogs and reduced water flow. Consulting with a professional plumber can help assess the condition of your pipes.

What are the environmental impacts of using different types of plumbing pipes?

The environmental impact varies by pipe material. Copper and PEX are generally considered more eco-friendly than PVC and galvanised steel, which can release harmful chemicals if not disposed of properly. Additionally, choosing durable pipes that require fewer replacements can reduce overall environmental impact.
