Installing propane gas line from tank to house like a Pro! Everything You Need to Know!

Installing propane gas line from tank to house in 7 steps

Here are the steps on how to install propane gas line from tank to house:

Determine the location of the propane tank:

  • The propane tank should be located at least 25 feet away from the house if it is larger than 100 gallons.
  • The area where the tank will go should have a firm ground base and be no more than 75 feet from where the delivery truck will be parked.

Dig a trench:

  • Dig a trench from the propane tank to the house.
  • The trench should be deep enough to bury the gas line and wide enough to allow for the gas line and any necessary fittings.

Install the gas line:

  • Install the gas line in the trench.
  • The gas line should be made of a material approved for propane use, such as copper or polyethylene.
  • The gas line should be buried at least 12 inches underground and protected from damage by rocks or other sharp objects.

Connect the gas line to the propane tank:

  • Connect the gas line to the propane tank using a regulator and a shut-off valve.
  • The regulator will reduce the pressure of the propane gas to a safe level for use in the house, and the shut-off valve will allow you to turn off the gas supply in case of an emergency.

Connect the gas line to the house:

  • Connect the gas line to the house using a gas meter and a shut-off valve.
  • The gas meter will measure the amount of propane gas used, while the shut-off valve will allow you to turn off the gas supply to the house in case of an emergency.

Test the gas line:

  • Test the gas line for leaks using a gas leak detector or soapy water.
  • If you detect a leak, turn off the gas supply and call a professional to repair the leak.

Install propane appliances:

  • Install propane appliances, such as a stove or water heater, ensuring they are fully installed and vented.
  • Make sure your contractor’s pressure test tag is visible on all propane appliances.

It’s essential to note that installing a propane gas line can be dangerous, and it should only be done by a licensed professional to ensure safety and compliance with local regulations.

What size propane line from tank to house?

  1. Distance and BTU Load: The distance between the propane tank and the house, as well as the combined BTU load of all appliances, are primary factors for determining the appropriate propane line size.
  2. 3/4-Inch Line for Typical Residential Installations: For propane tanks located less than 150 feet from the house and with a BTU load of less than 200,000, a 3/4-inch propane line is commonly adequate for a typical residential installation.
  3. Larger Line for Longer Distance or Higher BTU Load: If the propane tank is more than 150 feet away from the house or has a BTU load exceeding 200,000, a larger propane line, such as a 1-inch line or even larger, may be required to ensure proper propane delivery.
  4. Consult with a Qualified Propane Technician: It is highly recommended to consult with a qualified propane technician or professional who can assess the specific conditions of your installation, consider local codes and regulations, and make precise recommendations regarding pipe sizing for your unique needs.

What tools and materials are needed to install a propane gas line?

When installing a propane gas line, you’ll need various tools and materials for the job. Here’s a list of the necessary items:


  1. Wrenches: You’ll need wrenches to tighten fittings and connectors. Ensure the wrench size is appropriate for the size of your pipe and fittings.
  2. Hacksaw: If you need to cut your pipe to length, a hacksaw is essential. Always wear safety goggles when using power tools for cutting.
  3. Level: A level is crucial for ensuring that your piping is installed perfectly level, which is especially important in existing structures to prevent gas leaks due to sloping.
  4. Tape Measure: A tape measure helps determine the length of your piping run and the required fittings. Accurate measurements are crucial before installation.
  5. Pencil and Marker: Use a pencil and marker to make notations on your pipe and fittings regarding the type of gas and other important information for reference.
  6. Gas Leak Detector or Soapy Water: You’ll need a gas leak detector or soapy water to test the gas line for leaks, ensuring safety.


  1. Pipes and Fittings: You’ll require pipes and fittings in various sizes to match the length of your run and the type of gas you’re using. For natural gas, use black iron pipe, while for propane, opt for copper tubing. Ensure the fittings are compatible with your chosen pipe type.
  2. Tape and Pipe Cement: Use tape and pipe cement to seal all connections between pipe segments and fittings. Follow the manufacturer’s instructions carefully to ensure proper sealing.
  3. Regulator: A regulator is needed to reduce the pressure of propane gas to a safe level for use in the house.
  4. Shut-off Valve: The shut-off valve is essential for turning off the gas supply in case of an emergency.

What are the safety precautions to take when installing a propane gas line?

1. Acquire the Proper Permits:

   – Obtain the necessary permits before starting the installation to comply with local regulations and safety standards.
