Maintaining Your Natural Gas Pipes
Nicor Gas regularly monitors the pipelines up to your meter that deliver natural gas to your home or business for corrosion and leaks. You are responsible for maintaining the lines that begin at the meter and extend to the natural gas-burning equipment in your home or business, yard and any other buildings on your property.
If there is more than three feet between your meter and your home, Nicor Gas will monitor the primary pipeline. However, you are still responsible for repairs. (Nicor Gas does not monitor any fuel lines after the meter for business customers.)
You should periodically have your buried gas piping inspected for corrosion and leaks and have repairs made if any unsafe condition is found. Also, any repairs, locating and appliance connector replacements and inspections should only be performed by a plumbing contractor, heating contractor or other qualified professional. When excavating near buried gas piping, the piping should be located in advance, and the excavation done by hand.
