Can I Run My Own Natural Gas Line?

Many households in the northern half of the country will have to turn on their heating systems at the beginning of October. Natural gas is one of the most cost-effective and efficient fuels for a furnace or boiler. With its benefits come questions about safety and obligations for homeowners. It is your role as a home inspector to assist in the detection of flaws that may jeopardize the safety of residents in natural gas-powered homes. We’ll go through some of the fundamentals of gas piping inspection.

The gas supply line, also known as the building line, is the plumbing that runs throughout the house. Individual appliances are served by branch lines. The branch line finishes in a drop line, which is a vertical pipe that drops down from an overhead branch line to the appliance. If it carries gas up to an appliance from a branch line below the appliance, it’s called a riser.

A sediment trap or dirt pocket, commonly referred to as a drip leg, is normally present at the appliance connection point and consists of a nipple and a cap. This pipe extension, which is normally at least 3 inches long, is designed to catch any water or foreign material that may be present in the gas before it enters the appliance. The solids and liquids fall into the pocket, which is just a gravity mechanism.

The homeowner is normally responsible for the pipework downstream of the gas meter. The gas company is normally responsible for the piping upstream of the gas meter, as well as the meter itself.

Steel, copper, and brass are the most popular materials for gas piping. In some cases, galvanized steel, copper, brass, or CSST (Corrugated Stainless Steel Tubing) can be used, but copper is prohibited by some utilities. Copper is widely used in different parts of the world. You should be aware of what is considered acceptable in your neighborhood. Black steel piping with malleable iron or steel fittings is common. In other cases, galvanized steel is also used.

Flexible connectors are allowed to be used to connect appliances to gas pipelines. A shut-off valve must be installed at the rigid piping connection. This valve must be located in the same area as the appliance.

Accessible and three or six feet long: The flexible connectors cannot pass through walls, floors, or ceilings, and they cannot be hidden. Except for gas stoves and laundry dryers, the flexible connector length is normally limited to 3 feet. 6 feet is usually allowed for these equipment. Using nipples to splice or join connectors is frequently forbidden. Flexible connectors are only allowed in some jurisdictions for gas stoves, dryers, outdoor barbecues, and other semi-portable equipment. Flexible connectors may be prohibited on gas furnaces, water heaters, space heaters, and other similar appliances. Flexible connectors are more likely to be utilized on all appliances in earthquake-prone areas because they give some protection against gas piping leakage or rupture during an earthquake. To find out what is and isn’t permitted in your area, consult your local gas code.

The use of white thread seal tape (often referred to as Teflon tape) as a connecting compound for steel gas piping is not recommended. Cutting oils on the pipe threads from the manufacturing process may hinder the tape from sealing. Yellow thread seal tape is permitted in some regions. Pipe dope is favored and may be the only option available. You might wish to double-check with the gas company. Inquire about whether any piping installations with thread seal tape of any color should be reported as a defect.

Although certain exceptions exist, most appliances should have a shut-off valve nearby.

The use of gas piping as a grounding mechanism for the electrical service is prohibited by most authorities. In many countries, however, bonding the gas piping to the electrical grounding system is required. This is often accomplished by connecting the gas pipe to the supply water piping (assuming it is grounded) near the water heater. We want to keep the gas piping at zero electrical potential by attaching it to the grounding system to prevent an electrical potential building within it that could lead to arcing, which could ignite gas.

All of these issues have the potential to result in gas leaks and explosions.

Is it possible for a homeowner in Ontario to install a gas line?

There are a variety of reasons why a new gas piping system should be installed in Hamilton. The following are some of the most typical reasons to install a new gas line in your house or business:

It is highly recommended that you always contact a competent gas line installation specialist in Hamilton to handle the task, regardless of the purpose for the installation or replacement. For inexperienced and untrained persons who don’t know what they’re doing, working with gas lines can be quite dangerous.

This is not something you can learn on the internet, contrary to popular belief. Rather of jeopardizing your life and the lives of your neighbors to save a few dollars up front, contact a professional contractor who knows what they’re doing and has the necessary certifications.

Although it is theoretically permissible for property owners to build, relocate, repair, and maintain gas lines on their own in Ontario, it is highly ill-advised due to the significant hazards involved. You’ll need to get the work evaluated by a certified gas line technician or electrician before using it, in addition to getting the required permissions from municipal agencies.

Is it possible to run natural gas line around the outside of the house?

(1)All pipe, tubing, fittings, and other piping components between the tank and the first shutoff valve must be designed with a factor of safety of at least 8 based on the minimum specified tensile strength at room temperature for the full range of pressures, temperatures, and loadings to which they may be subjected.

All other pipe, tubing, fittings, and other pipeline components must be adequate for the full range of pressures, temperatures, and loads to which they may be exposed, with a factor of safety of at least four.

For plumbing systems with a working pressure more than 100 psi, underground piping must never be less than Schedule 80.

Any material utilized, including gaskets and packing, must be compatible with natural gas and the conditions in which it is used.

(2)All piping and tubing must be run as close to the source as possible, with suitable allowances for expansion, contraction, jarring, vibration, and settling.

Exterior pipe must be well supported and protected against mechanical damage, whether buried or put aboveground.

Unless otherwise protected, underground plumbing must be buried at least 18 inches below the ground’s surface.

All underground piping must be coated to prevent corrosion in accordance with Section 533(b) or an equivalent standard.

For piping below ground, zinc coatings (galvanizing) are not considered enough protection.

(3)All welded piping must be manufactured and tested in conformity with the ANSI Code for Pressure Piping, Petroleum Refinery Piping, B31.3, 1966 Edition or a similar code.

(4)All valves must be capable of withstanding the whole range of pressure and temperature that they may be exposed to.

The service ratings must be stamped or otherwise permanently marked on the valve body by the manufacturer.

Strainers, snubbers, and expansion joints, among other piping components, must be permanently marked by the manufacturer to show the service ratings.

All materials, such as valve seats, packing, gaskets, and diaphragms, must be resistant to natural gas action in the circumstances they are exposed to.

(A)Valves, cocks, fittings, and other piping components made of cast iron or semisteel that do not comply with ASTM Specifications A-536-67, Grade 60-40-18; A-395-68; A-47-68, Grade 35018; and A-445-66 unless they have pressure-temperature ratings of at least 1 1/2 times the design service conditions.

Valves made of cast iron or semisteel that do not meet the three ASTM criteria specified above should not be utilized as primary stop valves.

Is it possible to utilize PEX for a gas line?

PEX pipe is not the same as PE piping, and the two are frequently confused. Polyethylene, or PE, is a flexible plastic polymer that is ideal for piping in wells and other cold-water supply lines.

PEX stands for polyethylene that has been cross-linked. It’s made of polyethylene, a material with a stronger link between the polymer chains that make it up. PEX is now suited for both hot and cold water applications as a result of this advancement. It can also be utilized in some gas applications, depending on the building code.

PEX and PE are more flexible and have a significantly greater pressure rating than typical gas lines, thus they suit those requirements. They are, however, made of a soft material that could be damaged by nails, rodents, and other objects. As a result, in your location, either may not be permitted for use as a residential gas line. Even when the utility provider is able to install it, plumbers and homeowners are not always able to.

What type of natural gas pipe is utilized in homes?

Steel, black iron, polyvinyl chloride (PVC), high-density polyethylene (HDPE), and copper are the most popular materials used to build gas piping. Some of these materials are prohibited by some utilities, so check with your local utility to see what is permitted in your region before installing any. If you employ a professional to complete the task, they will be familiar with the local regulations.

Flexible Corrugated Stainless Steel Tubing

Corrugated stainless steel tubing is flexible and easy to install, and it works well in compact spaces and areas with a high risk of natural disasters. Flexible corrugated stainless steel tubing can crack over time, despite its ability to reduce damage. This material should only be used for indoor gas piping.

Galvanized Steel

Galvanized steel gas pipes are both energy efficient and long-lasting. Galvanized steel pipes are suitable for water supply lines since they may be used for both interior and outside gas lines. Because it is labor-intensive compared to other materials, this material is commonly found in older homes and is not used in new structures nowadays.

Black Iron

The most frequent material used to manufacture gas pipes, both inside and outside, is black iron. The substance is durable, heat resistant, and can be molded into an airtight seal. Black iron, on the other hand, can corrode and its sealant erode over time. Consider contacting a professional for routine maintenance if your gas pipes are constructed of black iron.


Because PVC gas pipes are sturdy and corrosion-resistant, they’re ideal for underground outside gas lines. Although PVC pipes are a cost-effective option, some places do not allow them since they can break during installation.


HDPE pipes, like PVC pipes, are appropriate for buried outside lines. Although these plastic pipes are flexible and affordable, they can be damaged by subsurface material such as rocks and tree roots.


Some towns do not allow copper gas lines, therefore their use is limited. Copper pipes have severe code requirements that limit their use due to their estimated life of 20 years.

Is it possible to run a gas pipe through a wall?

(1) No part of any installation pipework shall be installed in a wall, a floor, or a standing of solid construction unless it is constructed and installed in such a way that it is protected against failure caused by movement of the wall, floor, or standing, as the case may be.

What is the name of the yellow gas line?

In the gas business, HDPE pipe is less frequent and is typically used in non-residential applications with high pressures (up to 125 psi). HDPE pipe can be black, black with a yellow stripe, or black with a yellow outmost layer, whereas MDPE gas pipe is yellow.

Is it possible for a gas line to be made of copper?

Nothing, including copper, is corroded by natural gas. Corrosion is a chemical reaction that occurs when metal and oxygen come into contact. Any corrosion would be caused by the oxygen in the normal air that is mixed in with the gas. Heat and moisture can also hasten the rusting process. Is it conceivable that the pipe was clogged by humidity or water? Sorry, but I don’t have any information about gas pipe specifications! I strongly advise you to use whatever material is current under California law. Natural gas leaks aren’t something you want to take lightly.

Is it possible for me to undertake my own gas work?

When it comes to home upgrades, keep in mind that doing your own gas work won’t save you money; it could cost you your life.

Do not attempt to install, repair, or relocate gas appliances such as a boiler or cooker; instead, use a Gas Safe qualified engineer who has the necessary abilities to do so safely.

Unsafe gas work can result in a gas leak, a fire, an explosion, and carbon monoxide poisoning.

If you’re having construction work done on your house, make sure your contractor is qualified for the job. According to the HSE, if you need a new gas appliance installed or if an existing gas appliance needs to be removed or relocated for building work, your contractor must be Gas Safe registered.

All Gas Safe registered engineers carry an ID card that you may check to see if they are Gas Safe registered. You may also call Gas SafeRegister for free at 0800 408 5500 to see if the gas engineer is listed and qualified for the job you want. Go to the Gas Safe Register instead.

Is it legal for me to use my own gas stove in Ontario?

If you’re handy around the house and want to buy a few propane appliances for your house or cottage, you’re probably thinking whether you can install them yourself.

The answer is, unfortunately, no. In order to service and install gas appliances in Ontario, you must have the necessary training and certificates from the Technical Standards and Safety Authority (TSSA).

“A fuels safety technician is a certified professional who performs a variety of tasks, including installation, service, and maintenance, for various types of equipment that operate on gaseous fuels, fuel oil, and compressed gas, as set out in Ontario Regulation 215/01: Fuel Industry Certificates and all related regulations,” according to the TSSA website.

These restrictions in Ontario are in place to help you save money while also keeping your family safe. Budget Propane has outlined three important reasons why hiring a professional to install your propane equipment is critical:

Professionals are liable

Professionals that have been trained and licensed have their own insurance and are responsible for any damages to the appliance or your home that occur during the installation process. Before you choose a skilled and licensed installation, it’s critical to ask questions about this type of coverage.

It is safer for your family

Professionals receive training and certificates to ensure that they know exactly how to install the appliances while also ensuring propane safety and preventing leaks. They will know exactly how to handle each circumstance as it arises if something goes wrong during the installation.

Propane gas, while relatively safe compared to other forms of fuels, should not be messed with if you are unfamiliar with it.

They will ensure you have the right units

Professionals will not only be able to install and repair propane appliances properly and safely, but they will also be able to recommend the type or unit that is best for your needs.

For example, the type of hot water heater you require may be determined by the size of your home and family. Professionals may also be able to provide suggestions for companies that require less upkeep or have better user feedback.
