Factors To Consider Before Gas Line Installation

Before beginning the project, you need to know the type of gas line to install. Below are some of the factors to consider:

1. Cost Of Gas Pipe

The cost of pipe material varies for different types. Depending on your budget, you can find an affordable pipe that will serve your needs accordingly. Below are the price ranges of various materials:

  • Galvanized Steel: between USD$5 and USD$12 per linear foot
  • Black Iron: between USD$20 and USD$25 per linear foot
  • High-density polyethylene piping (HDPE): between USD$2 and USD$5 per linear foot
  • Flexible corrugated stainless-steel tube (CSST): between USD$8 and USD$10 per linear foot

Other factors like labor, location, and line length contribute to the cost. The labor charge for a licensed professional is high but worth it because you’re guaranteed an excellent job. The location of gas lines also matters. If the lines are inaccessible, the professional will spend more time tracing them and may have to do extra work like landscaping, adding to the cost. The professional requires more materials, time, and labor for a more extended gas line.

2. Geographical Location

Have in mind the kind of geographical location to install a gas line. Professionals recommend using flexible corrugated stainless-steel tubes (CSST) in areas prone to natural hazards. It’s advisable to refer to area safety code requirements and risk profiles concerning natural disasters that are common in the local area. This info will also help to determine the type of pipe to use in the area. 

3. Strength And Resilience

Gas pipe materials are different, so some are more durable than others. For instance, high-density polyethylene piping (HDPE) and black iron are among the most commonly used materials for gas pipe creation. It is because they’re strong, flexible, and heat resistant.   

4. Indoor Or Outdoor Fittings

Of the various gas pipe materials available, some are good for indoors, while others are best suited outdoors. Ensure that you select the type suitable for the gas line installation you need. Flexible corrugated stainless (CSST) is said to be the most favorable for indoors because of its flexibility, and it also fits well in tight spaces. High-density polyethylene piping (HDPE) is suitable outdoors because of its high resistance to cracks, corrosion, and punctures.

How To Install A Gas Line

Below are the steps to follow for gas line installation

1. Switch Off Gas Supply

Switch off your gas supply from the meter and confirm that by checking to see that the meter is not moving.

2. Get Proper Gas Pipes

Inquire from the gas company that your house is registered to get the appropriate pipes in size and materials.

3. Stretch Your Gas Line

Extend your gas line by fixing your appliances’ valves to the desired length. Ensure to use pipe dope and not tape to cover the threads of the pipe ends so that they’re airtight.

4. Connect Gas Line To Appliance And Confirm Airtightness

Connect the gas line to your appliance and pour soapy water over the pipe joints. Water bubbles indicate that there’s a leak. Correct that by tightening the joints using a wrench, and if the leak is still there, undo the pipes, join them all over again, and apply more pipe dope.

5. Turn On The Gas

Balance the valves to allow gas flow, then test by switching on your appliance to confirm gas flow.


Using gas is cheap and affordable but can be hazardous if not handled carefully. Ensure to observe all safety precautions throughout the installation process.
