Because there is still gas in the line even with the main turned off, you should not use any electrically driven tools to cut the pipe. A sawzall has the ability to start a fire. The preferred (safe) options are to use a wheel cutter or a hacksaw.
What is the best way to clear a natural gas line?
In other circumstances, it’s simply a matter of locating and removing the obstruction. Make sure the gas supply is shut off before proceeding.
Pushing a wire or a plastic probe into smaller gas lines, such as 3/8 or 1/2 flexible copper tubing or flexible stainless steel tubing, will sometimes clear the piping. Because the wire can mistakenly cut the interior of thin-walled gas piping, causing damage or perhaps a future point of corrosion and gas leakage, a plastic probe is preferred.
You may be able to run a 1/4 diameter drain auger through the piping run if the pipe is 1/2 or larger.
Cleaning natural gas pipes yourself is not recommended, especially if the obstruction is caused by corrosion, dirt, or insects. If you are unable to completely clean the pipe, any remaining material may choke a gas orifice or control, rendering the gas light inoperable or potentially dangerous. Pipe cleaning and unclogging should always be done by a registered professional gas piping business.
When you hire a competent gas line repair firm, you can rest certain that not only will the repairs be done safely and correctly, but they will also use a borescope to inspect the interior of the pipe, perhaps avoiding the need to replace the entire pipe.
If you find water in your gas line and it’s corroded, and/or the leak isn’t evident and can’t be fixed, the entire pipe will most likely need to be replaced because the pipe’s integrity has been compromised. To keep water out of the system, outdoor gas piping is frequently replaced with continuous, waterproof, flexible polyethylene gas piping with risers at the pipe entry and exit sites.

What is the length of time it takes to bleed a natural gas line?
The Lines Are Bleeding As the gas starts to flow, it could take anywhere from one to ten minutes to bleed air out of the pipes. Continue to press the valve knob inward for 30 seconds after the pilot is lighted before releasing it.
Is it necessary to bleed the natural gas line?
Bleeding a gas fireplace is yet another thing to add to our never-ending list of responsibilities. Because this isn’t a duty you have to do every day, it’s easy to forget about your furnace. So, why is it so crucial to bleed your furnace?
If there is air in the gas line, it is necessary to bleed the furnace. You won’t be able to light your gas furnace if this is the case.
But what is the source of this issue? If your gas line has air in it, it signifies there is a void in the line. Between the gas valve and the pilot assembly, there will be a void. This is due to the furnace being utilized infrequently. This could be for a variety of reasons.
What are the signs that my gas line is clogged?
Continue reading to learn about three typical gas line issues, their symptoms, and possible treatments.
1. Leak of Gas
A gas leak within the house is dangerous to the people who live there. Natural gas poisoning can occur when people and pets inhale the gas that has been discharged into the home air. Furthermore, a buildup of natural gas within a home can cause a fire or an explosion.
The smell of sulfur or rotten eggs in the home is one symptom of a natural gas leak. This odorant is added to gas by gas supply companies to aid in the detection of gas leaks. A gas bill that suddenly climbs for no obvious reason and home plants that all die or become wilted at the same time are other symptoms of a gas leak.
When there is a leak in the pipe that distributes natural gas to a certain home appliance, the equipment may make a hissing noise. Furthermore, you may detect gas bubbles rising to the surface of standing water in your yard if there is a leak in the gas line part buried in your yard.
Turn your home gas supply valve to the off position as soon as you observe one or more indicators of a natural gas leak in your home, and immediately contact a plumber who can diagnose and repair the gas leak.
2. Blockage of a gas line
A gas line obstruction is another common household gas line issue. Dirt and other debris, insects, tree roots, and even water can clog a gas line. A gas line, on the other hand, can acquire a bad dent or kink that prevents gas from flowing through it.
Gas-powered appliances that no longer work properly or at all are the most evident indicator of a natural gas obstruction. When you have a blockage in a gas line, your gas range may only create a low flame when a burner is set to high, or your gas water heater may take considerably longer to heat water than it used to.
As pressure rises on the gas line segment behind the blockage and exerts pressure on corroded or weak areas of the pipe, a gas line blockage can eventually lead to a gas leak.
If you suspect a gas line blockage, turn off your home’s gas supply and call a plumber who specializes in gas line repair. This specialist can locate the source of the clog and clear it with a special probe or drain auger, as well as evaluate your gas lines for any damage caused by the clog, such as a leak.
What is the best way to burp gas lines?
- Turn off your propane tank’s valve now. Twist it all the way to the end to turn it off.
Don’t fire up the grill right away. Allow at least 30 seconds for the gas tank to reconnect to the grill and the regulator to reset on its own. Reconnect and tighten the hose. Open the propane valve now. To avoid tripping the regulator, make sure you go slowly. After that, turn on the valve as well as the burner. Keep an eye on the flame of the burner. This time, the stakes should be tremendous. Make sure you turn them off one by one as you turn them off.
What does “purge a gas line” imply?
The initial air in freshly constructed natural gas pipelines must be purged before they can be placed into service. This eliminates the potential of a harmful air/natural gas mixture forming in the pipeline, which could cause combustible combinations.
Do not attempt to purge a gas line on your own; only a certified professional should do it. Consider the following additional safety precautions:
- Do not expel a gas line’s contents into a tight place or somewhere where gas could concentrate.
- Only a competent professional should purge gas in a well-ventilated location or by venting to the outside atmosphere.
- Identify and eliminate all sources of ignition in the region where the gas may be discharged before purging.
- To determine if natural gas is present during purging operations or when working on gas piping facilities, always utilize gas detection equipment. To detect the presence of natural gas, do not rely just on your sense of smell.
- Follow the manufacturer’s installation instructions and local code requirements when installing gas appliances or equipment.
