Prepare the other tools you’ll need for this job now that you have the pipes. A drill, a drill bit large enough to bore through a wall, a flare tool, and a pipe nipple are all required. Later, you’ll need a brush, a container, some soap, and water to perform a basic test.
Step 3: Connect the Pipes to Propane Tank
Now is the time to get the pipe. Locate the fitting on your pipe and secure it to the tank’s opening with a screw. To ensure that the connection between the tank and the pipe is secure, tighten the fitting.
What am I able to use as a propane 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 to utilize PEX for a propane 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 subterranean propane pipe is used?
The service plumbing, also known as the yard line, is the gas line that travels between the tank and the structure that houses the gas appliances. Copper tubing or plastic polyethylene piping are commonly used in propane yard lines. For the entire exterior section of the installation to be safe and serviceable, the service piping must be installed appropriately and legally in conjunction with the propane tank.
The visible portion of the yard line is where it emerges from the ground adjacent to the tank, as well as where it enters the structure or links to a source of usage, such as a generator or pool heater. For any section of a propane gas service line, only certified materials and fittings should be utilized. PVC, rubber hose, and flex lines are prohibited and should not be utilized in any component of the gas service line.
Is it possible to have propane tanks close to the house?
Residential propane tanks are simply tanks that have been filled with propane. That propane is extremely flammable and has a hard time with high temperatures. That’s why there are safety precautions in place (such as how far away a propane tank must be from the house).
They certainly can be. ‘Stationary aboveground propane tanks’ are the name for these tanks. Propane tanks, on the other hand, must be placed in accordance with municipal, state, and federal requirements.
We’ll go over the fundamentals of propane tank positioning for tanks with capacities of 100, 500, 1,000, and 2,000 gallons. Example: How far away from the house must a 250-gallon propane tank be? The minimum distance is 10 feet from the home (or, more precisely, from the opening of a building; in other words, from the window).
The Department of Housing and Urban Development is in charge of regulating propane tank placement on private land (HUD). In 2020, they released a new document titled “Conforming the Acceptable Separation Distance (ASD) Standards for Residential Propane Tanks to Industry Standards,” which deals with the minimum distances for propane tanks.
Let’s start with a 100-gallon propane tank and work our way up to 500-gallon, 1,000-gallon, and 2,000-gallon tanks.
It’s worth noting that some laws are state-specific. We’ll go over the basic rules that normally apply, but you should be aware that some states may have somewhat different minimum distances.
What size propane pipe do I need?
Section 1 requires 1/2 inch pipe to feed outlets A and B, or 35 cubic feet per hour. Section 2 requires 1/2 inch pipe to serve outputs A, B, and C, or 94 cubic feet per hour. 3/4 inch pipe is required in Section 3 to supply outlets A, B, C, and D, or 230 cubic feet per hour.
Is it possible to use black pipe for propane?
Running black iron pipe for propane use may appear to be a difficult process, and you will pay a professional to complete it. The truth is that this is a great do-it-yourself project if you have the necessary tools and some basic pipe fitting knowledge.
This can be done in an afternoon depending on how much pipe needs to be installed, potentially saving you hundreds of dollars in installation fees.
