How to Extend Gas Line for Dryer: A Step-by-Step Guide


Extending the gas line for your dryer is a task that can save you money by allowing you to place your dryer exactly where you want it. This guide will provide you with the necessary steps to extend the gas line safely and efficiently.

Safety Precautions

Before you start, safety should be your top priority. Always wear safety goggles and gloves, and ensure the gas supply is turned off. Keep the area well-ventilated, and have a fire extinguisher nearby in case of emergencies.

Gather Your Tools and Materials

To extend the gas line, you will need a few tools and materials, including a pipe cutter, pipe wrench, gas sealant, Teflon tape, flexible gas line, and a gas shut-off valve. Make sure to have all these items ready before you begin.

Shut Off the Gas Supply

Locate the gas shut-off valve near the existing gas line and turn it off. This will ensure that no gas is flowing while you work on the extension.

Disconnect the Old Gas Line

Carefully disconnect the old gas line from the dryer. Use a pipe wrench to loosen the fittings and remove the line. Be cautious not to damage the fittings during this process.

Measure and Plan Your Extension

Measure the distance from the existing gas line to the new location of your dryer. Ensure you have enough flexible gas line to cover this distance. Plan the route for the new line, keeping it away from sharp edges or potential sources of damage.

Install the New Gas Line

Attach one end of the flexible gas line to the shut-off valve and the other end to the dryer. Use Teflon tape on the threads to ensure a tight seal. Secure the line with pipe clamps.

Test for Leaks

Turn on the gas supply and use a mixture of soap and water to check for any gas leaks. Apply the soapy solution to all the connections and watch for bubbles. If you see any bubbles forming, tighten the connections further until they are completely sealed.

Reconnect the Dryer

Reconnect the dryer to the new gas line and ensure all connections are secure. Double-check that there are no kinks or sharp bends in the flexible gas line.

Turn On the Gas Supply

Turn On the Gas Supply

Turn on the gas supply at the shut-off valve. Make sure to do this slowly and listen for any hissing sounds, which could indicate a leak. If you hear hissing, turn off the gas immediately and recheck the connections.

Test the Dryer

Run the dryer on a test cycle to ensure it is receiving gas and functioning properly. Check for any unusual smells or noises.

Final Checks and Inspection

Inspect all connections one last time to ensure there are no leaks. Tighten any fittings if necessary. Once you are satisfied that everything is secure, your gas line extension is complete.

Additional Tips and Considerations

Gas Line Sizing

Ensure that the diameter of the new gas line matches the specifications of your dryer and the distance it needs to cover. Gas line sizing is crucial to ensure proper gas flow and appliance performance. Consult your dryer’s manual or a professional if you are uncertain about the appropriate size.

Local Regulations

Always check local building codes and regulations before extending a gas line. Some areas may have specific requirements or inspections that need to be followed when working with gas lines. Complying with these regulations is essential for safety and legal reasons.

Professional Assistance

While this guide provides a comprehensive overview of extending a gas line for your dryer, some situations may be more complex. If you encounter challenges or if you lack experience in gas line installations, it’s advisable to seek the help of a licensed professional. They have the expertise and tools to ensure a safe and reliable installation.


Regularly inspect your gas line and connections for signs of wear, corrosion, or leaks. Perform these checks at least once a year to maintain the safety and efficiency of your gas dryer. If you notice any issues, address them promptly to prevent potential hazards.

Emergency Response

In case of a gas leak or suspected gas leak, follow these immediate steps:

  1. Turn off the gas supply at the main shut-off valve.
  2. Open all windows and doors to ventilate the area.
  3. Do not use any electrical switches, appliances, or open flames.
  4. Evacuate the premises and move to a safe location.
  5. Call your gas company’s emergency hotline or 911 for assistance.

Measure and Plan Your Extension

Before you start extending the gas line for your dryer, it’s crucial to measure and plan the extension carefully. Proper planning ensures that you have the right materials and that the installation goes smoothly. Here’s a step-by-step guide on how to measure and plan your gas line extension:

Determine the New Location

Decide where you want to place your gas dryer. Measure the distance from the existing gas line to this new location. Ensure you have a clear path for the gas line without any obstructions or tight bends.

Check Gas Line Compatibility

Check the compatibility of the existing gas line with your dryer and the new location. Ensure that the diameter of the gas line matches the specifications required for your dryer. If necessary, consult your dryer’s manual or a professional to determine the appropriate size.

Select the Gas Line Material

Choose the type of gas line material you will use for the extension. Flexible gas lines are commonly used for these types of projects due to their ease of installation and flexibility in routing. Make sure the material is approved for use with natural gas or propane, depending on your setup.

Plan the Route

Plan the route for the new gas line from the existing gas line to the new dryer location. Avoid running the gas line near sharp edges, electrical wiring, or areas where it might be accidentally damaged. Ensure that the line follows a safe and direct path.

Calculate the Required Length

Measure the total length of the gas line required for the extension. Allow some extra length for flexibility but avoid excessive coiling or bending. It’s better to have a slight excess than a gas line that is too short.

Acquire Necessary Materials

Based on your measurements and planning, gather all the materials you will need for the extension, including the flexible gas line, pipe clamps, Teflon tape, and any additional fittings or connectors required.

Consult Local Regulations

Before proceeding, check local building codes and regulations regarding gas line extensions. Some areas may have specific requirements, and it’s essential to comply with these regulations for safety and legality.


Extending a gas line for your dryer is a manageable DIY project when approached with safety and careful planning. By following these steps, you can confidently relocate or install your gas dryer, enjoying the flexibility it offers in your laundry room setup.
