Gas Leak Repair questions, answered by experts

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).

Yes. There are a variety of standard pipe sizes used in plumbing. The main supply line connecting your home to the street is either 3/4 or 1 inch in diameter. Supply lines are 3/4 inch in diameter. Individual components are 1/2 inch in diameter. Meanwhile, your main drainpipe is often 4 inches wide. Most shower and bathtub drains are 2 inches in diameter, most toilet drains are 3 inches in diameter, and most sink drainpipes are 1 1/4 or 1 ½ inches in diameter.

The best way to reset this valve is to contact your utility provider to do so safely. If the pipes are damaged and you reset the valve anyway, it could lead to a gas leak. It’s important to call in a pro as soon as you can to reconnect your gas supply after an earthquake and ensure the device will work again the next time there’s a quake.

Common signs of gas line leaks include a rotten egg smell, hissing sounds, dead plants around the area of the leak, and unexplained physical symptoms like dizziness and nausea. If you notice any of these signs, act immediately. Shut off the gas supply to your home and call a pro to assess the situation.

It can cost anywhere from $200 to $5,000 to repair a gas line. The cost may vary depending on where the problem is located. For example, if there’s a small gas leak somewhere that’s easy to access, the cost could be on the lower side. On the other hand, repairing buried lines and lines in other hard-to-reach areas will be more expensive.
