Understanding the Full-House Repipe Process

A full-house repipe replaces the entire network of water supply lines. Homes in regions with older construction or corrosive water conditions may experience issues such as pinhole leaks, internal pipe corrosion, or slab leaks. Replacing the system provides new pathways for water flow and brings the plumbing up to current code.

Before any work begins, technicians evaluate the home’s layout, the materials in use, and the condition of the system. This evaluation helps determine the overall scope and sequence of the project.

What to Expect During a Full-House Repipe

A repipe starts with an assessment of the existing water system. This step ensures that the layout and materials of the new system are appropriate for the home.

Full-System Evaluation

The inspection typically includes identifying pipe materials, checking water pressure, reviewing visible areas for corrosion or leaks, and noting any signs of slab movement or water intrusion. This information helps guide the planning for the repipe.

Detailed Work Outline

Following the inspection, a written outline or proposal is prepared. This document explains the planned routing, materials, fixture count, and general expectations for the work. Clear documentation helps ensure that the project proceeds according to the agreed-upon scope.

Step 1: Initial Inspection and Plumbing Assessment

Once planning is complete, the home is prepared for the repipe. This preparation helps maintain a clean and organized work environment.

Preparing the Home for Work

• Protecting floors and walkways

• Setting up dust containment

• Preparing tools and access locations

• Coordinating fixture count and supply routes

  
  

Homeowners may be asked to:

• Clear under-sink cabinets

• Remove items near plumbing access points

• Make the water heater and laundry area accessible

  
  

These steps allow the work to proceed efficiently and reduce the amount of time water is shut off.

Step 2: Opening Access Points in Walls and Ceilings

After preparation, technicians create access to the existing plumbing. Access points allow them to remove old lines and install new ones.

Strategic and Minimal Openings

Openings are placed near fixtures or plumbing pathways to minimize the amount of drywall affected. Technicians use caution to avoid electrical wiring, framing, and HVAC components.

This step often includes:

• Identifying pipe locations behind walls

• Cutting strategically placed openings

• Avoiding electrical and HVAC lines

• Using proper detection tools

• Maintaining clean work areas

  
  

Step 3: Installing the New Piping System

With access established, the new piping system is installed. This is the central phase of the repipe.

Selecting the Right Material

PEX or copper is commonly used depending on water quality, routing needs, and homeowner preference. Both materials meet plumbing code requirements.

Routing and Fixture Connection

Technicians route new hot and cold supply lines to each fixture, including sinks, showers, toilets, bathtubs, laundry connections, and the water heater. Proper fastening and placement help ensure stable operation and consistent water pressure.

Quality Control During Installation

Throughout the installation, technicians monitor alignment, securing, and connection integrity to confirm that the new system functions properly.

Step 4: Pressure Testing Every Line

Before closing any walls, the new piping system is tested to verify proper performance.

Typical steps include:

• Pressurizing the system to confirm performance

• Checking for leaks or irregularities

• Making any necessary adjustments

• Preparing for city inspection if required

• Ensuring compliance with local plumbing code

  
  

Pressure testing ensures that the system is functioning correctly before moving forward.

Step 5: Patching, Texture Matching, and Cleanup

Once the system has passed testing, the access points are repaired and the home is cleaned.

Wall Repair

Openings are patched using appropriate backing material and joint compound. Texture is matched as closely as practical to the surrounding surfaces. Final painting, if desired, is typically completed by the homeowner or a painter of their choice.

Final Cleanup

The workspace is cleaned, dust is removed, and surfaces are wiped down. This step restores normal living conditions and completes the interior restoration portion of the project.

Step 6: Final Walkthrough With the Homeowner

After the installation, testing, and patching phases are complete, the final walkthrough ensures that the homeowner understands the work performed and the functionality of the new system. This stage serves as a confirmation that all components operate correctly before the project is considered complete.

Complete System Demonstration

During the walkthrough, each fixture is turned on to verify proper water flow, stable pressure, and correct hot and cold orientation. This allows the homeowner to observe the performance of the new system in real-time and confirm that everything functions as expected.

Review of the Work

The homeowner is shown where new piping was routed and how access points were repaired. Any relevant documentation, such as information on materials used or general maintenance recommendations, is reviewed. This helps the homeowner understand the layout of the new system and what was completed during the repipe.

Project Closeout

Once the walkthrough is finished, the project is considered closed out. At this stage, the homeowner has the opportunity to ask procedural questions, clarify details about the installation, and confirm that all agreed-upon work has been completed. Any notes regarding future inspections or finishing work, such as paint touch-ups if desired, are addressed at this time.
