Plumbing is the lifeline of any home, ensuring water flows where it’s needed and waste is carried away efficiently. But what happens when you need to change the layout of your home or repair damaged pipes? That’s where rerouting house plumbing comes into play. Whether you’re remodeling your kitchen, fixing a slab leak, or upgrading an outdated system, rerouting plumbing is a critical task that requires careful planning and execution.
Understanding Plumbing Rerouting
What Does Rerouting Plumbing Mean?
Rerouting plumbing involves changing the path of your home’s water supply and drainage pipes. Instead of repairing or replacing pipes in their current location, rerouting redirects them to a new path, often to accommodate structural changes or avoid problematic areas.
Common Scenarios Requiring Rerouting
There are several situations where rerouting plumbing becomes necessary:
- Home Renovations: Remodeling a kitchen or bathroom often requires relocating fixtures, such as sinks, toilets, or showers, which necessitates rerouting the pipes.
- Slab Leaks: When pipes under a concrete slab develop leaks, rerouting is often more cost-effective and less invasive than breaking through the slab.
- Layout Changes: If you’re adding a new room or changing the layout of an existing one, rerouting ensures the plumbing aligns with the latest design.
Benefits of Rerouting Plumbing
Rerouting isn’t just about solving problems—it can also improve your home’s plumbing system:
- Improved Water Flow: Newer materials and optimized layouts can enhance water pressure and flow.
- Accessibility: Pipes in more accessible locations are easier to maintain and repair.
- Updated Materials: Rerouting allows you to replace old, corroded pipes with modern, durable materials, such as PEX or PVC.
Assessing Your Current Plumbing System
Before you start rerouting, it’s essential to understand your home’s existing plumbing system. Here’s how to get started:

Locating Key Components
- Main Water Supply: Identify where the main water shutoff valve is located. This is crucial for safely working on your plumbing.
- Sewer Lines: Locate the main sewer line to avoid accidental damage during rerouting.
- Existing Pipes: Trace the path of your current pipes to understand their layout.
Mapping Your Plumbing System
Creating a detailed map of your plumbing system is vital. Use tools like:
- Plumbing Blueprints: If available, these provide a clear picture of your home’s plumbing layout.
- Inspection Cameras: These can help you see inside pipes and identify potential issues.
Safety Considerations
Working with plumbing can be risky. Always:
- Turn off the water supply before starting.
- Wear protective gear.
- Be cautious of hidden hazards, such as electrical wiring or gas lines.
If the task feels overwhelming, don’t hesitate to call a professional plumber for an assessment.
Planning Your Plumbing Reroute
Proper planning is the foundation of a successful plumbing reroute. Here’s how to do it:
Step-by-Step Planning Process
- Assess Your Needs: Determine why you’re rerouting and what changes are required.
- Design the Layout: Plan the new pipe routes, keeping efficiency and accessibility in mind.
- Gather Materials: Choose the right pipes, connectors, and tools for the job.
- Obtain Permits: Check local building codes and secure any necessary permits.
Designing a New Plumbing Layout
When designing your layout, consider the following:
- Fixture Placement: Ensure sinks, toilets, and showers are positioned for convenience and functionality.
- Pipe Routes: Minimize the length of pipes to reduce costs and improve water pressure.
Avoiding Common Planning Mistakes
- Don’t overlook local building codes—they’re there for safety and efficiency.
- Avoid running pipes through areas prone to freezing, like exterior walls in cold climates.
- Plan for future maintenance by keeping pipes accessible.

Choosing the Right Materials for Rerouting
The materials you choose for your plumbing reroute can significantly impact the project’s success. Here’s a breakdown of common options:
Material Pros Cons
PEX Flexible, easy to install, resistant to freezing Not UV-resistant, may degrade over time
Copper is Durable, long-lasting, and resists bacteria. It is Expensive and prone to corrosion in acidic water.
PVC Affordable, lightweight, easy to work with Not suitable for hot water, brittle in cold temperatures
Recommendations
- Use PEX for its flexibility and ease of installation, especially in tight spaces.
- Opt for copper in areas with high water pressure or where durability is a priority.
- Choose PVC for drainage pipes due to its affordability and lightweight nature.
Essential Tips for Rerouting Plumbing Lines
Rerouting plumbing can be tricky, but these tips will help you avoid common pitfalls:
- Avoid Exterior Walls: In cold climates, pipes in exterior walls are prone to freezing and bursting.
- Mark Hidden Structures: Identify and avoid damaging electrical wiring, gas lines, and HVAC systems.
- Use Flexible Piping: PEX pipes are ideal for navigating complex routes and tight spaces.
- Secure Pipes Properly: Use clamps and brackets to prevent movement and reduce noise.
- Test as You Go: Check for leaks after each connection to avoid costly mistakes later.
Techniques for Rerouting Plumbing
There are several methods for rerouting plumbing, depending on the scope of your project:
Common Rerouting Methods
- Partial Pipe Replacement: Ideal for small repairs or minor layout changes.
- Full System Overhaul: Necessary for extensive renovations or replacing outdated systems.
Step-by-Step Process
- Disconnect Old Pipes: Shut off the water supply and carefully remove the existing pipes.
- Install New Pipes: Follow your planned layout, ensuring proper slope for drainage pipes (1/4 inch per foot).
- Secure Connections: Use appropriate techniques, such as soldering for copper or clamps for PEX.
When to Call a Professional
If you’re dealing with complex systems, lack experience, or need to comply with strict building codes, hiring a licensed plumber is the safest option.
Testing and Inspecting Your New Plumbing System
Once the rerouting is complete, it’s time to test and inspect your work:
Testing for Leaks
- Turn on the water supply and check all connections for leaks.
- Use a pressure gauge to ensure the system maintains proper pressure.
Professional Inspections
Schedule an inspection to ensure your plumbing meets local codes and is safe for use.
Cost and Time Considerations
Typical Costs
The cost of rerouting plumbing varies depending on factors such as materials, labor, and the extent of the project. On average:
- Small Projects: $500–$2,000
- Large Projects: $5,000–$15,000
Budgeting Tips
- Plan for unexpected expenses by setting aside an extra 10–20% of your budget.
