Gas Leak Repair questions, answered by experts

The biggest disadvantage of propane is that heating systems and appliances powered by propane tend to cost more than gas-powered ones. Propane is also dangerous since it can create frostbite if it touches the skin and can easily combust if mishandled. It’s also quite cumbersome to buy or replace propane tanks, so many people choose to have propane delivered to their homes—an extra cost and logistical challenge that can be a headache.

Safety steps include proper vent installation, connector tightness, and leak testing. A safe environment must be maintained throughout.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.

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.

Shut-off valves, like any other piece of metal hardware, can corrode, age, get worn down, and eventually break or rust into place. Occasionally spray your shut-off valve with WD-40 to stall it from rusting. If it really gets stuck, a wrench and WD-40 will usually do the trick, but you will need to call a plumber if it’s completely unmovable.
