Gas Leak Repair questions, answered by experts

In some ways, yes, and in some ways, no. As for how they’re the same, propane and gas both burn via the same process, combustion, and at the same temperature, around 3,600 degrees Fahrenheit. The difference is that propane produces more heat per unit than gas. One cubic foot of propane contains 2,516 BTU, while one cubic foot of gas contains 1,030 BTU.

The best sealant for gas pipes is usually a pipe joint compound, or pipe dope. It creates a durable, leak-proof seal that is resistant to high pressure and vibrations, and it doesn’t break down like tape can. Yellow Teflon tape, or PTFE tape, can also be a good option and is a safe and reliable sealant for gas pipes when you or a pro apply it correctly.

While some building codes allow galvanized pipe for natural gas, it shouldn’t be used for propane. Propane can cause the pipe to wear down, leading to dangerous leaks. Instead of galvanized piping for propane, you should consider coated copper, black iron, or corrugated stainless steel tubing (CSST). For underground propane line installation, you can use polyethylene (PE).

Element, gas features, and complexity, including venting and connections, are typically higher due to safety and expertise factors.

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.
