Running conduits behind drywall can be a practical solution for concealing electrical wiring in residential and commercial buildings.
It allows for a clean and organized appearance while ensuring the safety and compliance of the electrical system.
Running conduit behind drywall is a viable option for concealing electrical wiring. Conduit provides a protective pathway for wires, ensuring their safety and allowing for future access and modifications.
This article will explore the feasibility and considerations involved in running conduits behind drywall.
Understanding Conduit and Drywall
What is Conduit? Conduit is a protective piping system used to house electrical wires. It provides mechanical protection, prevents wire damage, and allows for future access and modifications.
What is Drywall? Drywall, or gypsum board or plasterboard, is commonly used for interior walls and ceilings. It is a panel made of a gypsum core encased in paper, providing a smooth and sturdy surface.
Can you run the conduit behind a drywall?
Yes, you can run conduit behind drywall. Running conduit behind drywall is a viable option for concealing electrical wiring.
Conduit provides a protective pathway for wires, ensuring their safety and allowing for future access and modifications.
By installing conduit behind drywall, you can achieve a clean, organized appearance while complying with electrical codes and regulations.
It helps protect the wires from damage, facilitates easy maintenance, and offers the flexibility to upgrade or modify the electrical system as needed.
The Purpose of Running Conduit
Running conduit behind drywall serves several purposes:
- Concealment: Conduit allows for the neat and hidden installation of electrical wiring, maintaining the aesthetics of the space.
- Protection: Conduit shields the wires from potential damage, such as impacts, moisture, or accidental contact.
- Accessibility: It provides easy access to the wiring for future maintenance or upgrades.
- Compliance: In many jurisdictions, running conduit is required by electrical codes to ensure safety and adherence to regulations.

Factors to Consider Before Running Conduit Behind Drywall
Before undertaking a project involving conduit behind drywall, consider the following factors:
- Building Codes and Regulations: Familiarize yourself with local building codes and regulations to ensure compliance. These codes specify the types of conduit, installation methods, and spacing requirements.
- Electrical Requirements: Determine the electrical load and the appropriate wire size and type needed. Consult an electrician if necessary.
- Structural Considerations: Identify potential obstructions or structural elements within the walls, such as studs, pipes, or HVAC ducts, which may affect conduit placement.
- Accessibility and Future Maintenance: Evaluate the need for future access to the wiring, as certain installations may require conduit runs that are easily accessible for repairs or modifications.
Types of Conduits Suitable for Concealed Installations
Several types of conduit are suitable for concealed installations behind drywall:
- Electrical Metallic Tubing (EMT): EMT is a lightweight and cost-effective conduit made of steel. It is easy to bend and install, making it a popular choice for residential applications.
- Rigid Metal Conduit (RMC): RMC is a heavy-duty steel conduit that provides superior protection against physical damage. It is commonly used in commercial and industrial settings.
- Intermediate Metal Conduit (IMC): IMC is a steel conduit that combines the strength of RMC with the lighter weight of EMT. It offers a balance between protection and ease of installation.
- Flexible Metal Conduit (FMC): FMC is a flexible conduit composed of interlocking metal strips. It is suitable for curved or irregular paths but provides less protection than rigid conduits.
- Non-Metallic Conduit: Non-metallic conduits, such as PVC (polyvinyl chloride) or HDPE (high-density polyethylene), is lightweight, corrosion-resistant, and easy to install. It is commonly used in residential applications.

Installation Process for Running Conduit Behind Drywall
Running conduit behind drywall involves several steps:
- Planning and Measurements: Determine the conduit route, take accurate measurements, and mark the locations for access points and fittings.
- Tools and Materials Required: Gather the necessary tools, including conduit benders, fish tapes, wire cutters, and drill bits. Acquire the appropriate conduit, connectors, fittings, and junction boxes.
- Creating Access Points: Cut openings in the drywall at the designated access points for installing the conduit and pulling wires.
- Securing the Conduit: Attach the conduit to the wall using appropriate supports and fasteners. Ensure proper spacing and secure the conduit firmly.
- Pulling Wires: Use fish tapes or cable pullers to guide and pull the wires through the conduit. Take care not to exceed the conduit’s fill capacity.
- Sealing and Finishing: Seal any gaps or openings around the conduit to maintain the fire-resistant qualities of the wall. Repair and finish the drywall surfaces to restore their original appearance.
Potential Challenges and Solutions
Running conduit behind drywall may pose challenges that require careful consideration and problem-solving:
- Obstacles and Obstructions: Identify and address any obstructions within the walls, such as existing wiring, plumbing, or HVAC systems. Modify the conduit path or consult professionals for guidance.
- Navigating Corners and Angles: Use appropriate conduit bending techniques and fittings to navigate corners, turns, or angles smoothly.
- Dealing with Existing Wiring: When encountering existing wiring, ensure proper separation and avoid interference or damage by using separate conduit runs or appropriate separation methods.
- Maintaining Bend Radius: Adhere to the manufacturer’s specifications for maintaining proper bend radius when bending conduit. Excessive bending can damage the conduit or affect wire performance.
Safety is paramount when working with electrical systems. Follow these safety guidelines:
- Working with Electrical Systems: Prioritize safety by turning off the power to the area where you are working. Use appropriate personal protective equipment (PPE) and follow electrical safety protocols.
- Proper Handling of Conduit and Wiring: Handle conduit and wires carefully to prevent damage and maintain insulation integrity. Avoid sharp bends or kinks that may impede wire performance.
- Testing and Inspecting the Installation: Once the conduit and wiring are installed, conduct thorough testing and inspection to ensure proper functioning and compliance with electrical standards.
Hiring a Professional vs. DIY Approach
Deciding whether to hire a professional or take a DIY approach depends on various factors:
- Benefits of Hiring a Professional: Professionals possess expertise, knowledge of local codes, and experience with complex installations. They ensure safety, compliance, and quality workmanship.
- DIY Considerations: DIY projects can be cost-effective and rewarding for those with sufficient knowledge and skills. However, consider the complexity of the installation, local regulations, and your comfort level with electrical work.
Running conduit behind drywall offers an efficient and aesthetically pleasing way to conceal electrical wiring.
By understanding the considerations, selecting the appropriate conduit type, and following proper installation techniques, you can successfully incorporate conduit within your walls while adhering to safety standards and building codes.
