Repiping is the process of replacing the water supply lines in your home. These pipes deliver fresh water to your fixtures and appliances. Over time, pipes corrode, leak, and become inefficient. Repiping is a significant investment that safeguards your home from costly water damage and ensures clean, safe drinking water.
Leaking pipes, low water pressure, discoloured water, and frequent plumbing repairs often signal the need for repiping. Repiping eliminates these issues, increases property value, and provides peace of mind. This guide will navigate the complexities of repiping, empowering you to make informed decisions for your home.
Signs Your Home Needs Repiping
Recognizing the signs that indicate your home requires repiping can prevent significant plumbing issues and costly repairs in the future. Here are some key indicators to watch out for:
- Age of your home: The age of your home significantly influences its need for repiping, as older homes, particularly those built before the 1970s, often have outdated plumbing systems. Galvanized steel pipes, commonly used in older homes, are susceptible to corrosion and rust, leading to leaks, reduced water pressure, and potential health risks.
- Discoloured water: If you notice that your water is discoloured, such as rusty or brown, it could be a sign of corrosion in your pipes. This is particularly common in homes with galvanized steel pipes, which are prone to rust and mineral buildup. Discoloured water can affect the taste, odour, and appearance of your water, and may even contain harmful contaminants.
- Low water pressure: Lower water pressure in your home may indicate plumbing issues, triggered by mineral deposits, corrosion, or sediment buildup in pipes. This can hinder daily tasks like showering, washing dishes, or lawn watering.
- Frequent leaks: If you experience recurring leaks, despite repairs, it’s a strong indication that your plumbing system is failing and requires attention. Leaks can occur in various parts of your plumbing system, including pipes, fittings, and fixtures. Ignoring leaks can lead to water damage, mould growth, and increased water bills.
- Noisy pipes: Banging or clanging sounds in your pipes, often referred to as “water hammer,” can be caused by loose or damaged pipes. Water hammer occurs when water pressure fluctuates rapidly, causing pipes to vibrate and make noise. This can be a sign of underlying plumbing issues, such as worn-out pipes or faulty valves.
- Visible corrosion: Corrosion or leaks on exposed pipes indicate an internal plumbing system issue, as corrosion weakens pipes and increases their vulnerability to leaks and breaks. Visible signs include rust, pitting, or discoloration on the pipes’ surface.
Types of Repiping Materials

Modern plumbing systems utilize various piping materials, each with its own advantages and considerations. Understanding these options will help you choose the most suitable material for your repiping project.
- Copper: Copper pipes are a common option because of their resilience to corrosion, longevity, and capacity to inhibit the development of bacteria. They also last a long time and are reasonably simple to install.
- PEX (Cross-linked polyethylene): PEX pipes are flexible, resistant to corrosion and scale buildup, and can withstand freezing temperatures better than rigid pipes. They are also more cost-effective than copper.
- CPVC (Chlorinated polyvinyl chloride): CPVC is a rigid plastic piping material known for its high heat resistance and durability. It is commonly used for hot water supply lines.
The Repiping Process
Repiping is a multi-stage process that involves careful planning and execution. While the specifics may vary depending on your home’s layout and the extent of the repiping, here’s a general overview:
- Assessment and planning: A qualified plumber will thoroughly inspect your current plumbing system, identifying scope of work, potential challenges, and suitable materials. They will consider factors like home age, system layout, and budget to create a comprehensive repiping plan.
- Permit acquisition: In most jurisdictions, repiping requires a permit. Your plumber can assist with obtaining the necessary permits, ensuring compliance with local building codes and regulations.
- Preparation: Before repiping, your home’s water supply will be cut off, and furniture and belongings may need to be moved for access to plumbing lines. Your plumber will protect your home by covering floors and furniture with drop cloths.
- Pipe removal and replacement: The old pipes will be removed carefully to minimize disruption, while new pipes will be installed according to the planned layout, ensuring proper connections and water flow, using specialized tools and techniques.
- Testing and inspections: Once the repiping is complete, your plumber will conduct thorough tests to ensure that the new plumbing system is functioning properly. This may include pressure testing to identify any leaks or weak points. Local building inspectors may also conduct inspections to verify compliance with building codes.
