Service Line & Tap

  • Columbia Gas will install the complete service. Please contact the New Business Team at 800-440-6111 at least 30 days prior to needing gas service.


  • Please contact the New Business Team at least 30 days prior to needing gas service.
  • Service line, tap and meter will be installed at the same time; if site is ready.
  • House must be under roof.

How to Get a Tap

  • The meter location should be clearly marked on the foundation and fuel line stubbed out.
  • Area near service line, tap and meter location needs to be clear of debris and physical obstructions and within 6” of the final grade.
  • All private underground utilities shall be marked by the applicant to clearly identify their physical location (including sewer lines, laterals, drain fields, etc.)

How to Get a Meter

If your construction is located within an area requiring a city inspection prior to the gas service being established in the building, a city building inspection sticker or report needs to be available at your site prior to requesting a gas meter being set.

Important: Fuel line(s) and appliance(s) must have been installed in accordance with the "National Fuel Gas Code"; and manufactured home installations shall be in accordance with Title 24, Code of Federal Regulations, Part 3280, Subpart H.
When the fuel line(s) and equipment, if applicable, have been installed, inspected, and tested, the party responsible for the payment of the gas bill should call our New Business Team at 800-440-6111 to schedule the meter installation. The required Columbia Gas inspection and testing will be done at the time the meter is installed.

The section of fuel line piping which extends through the outside wall to connect to the meter setting must extend:

  • 4-6 inches outside the building wall, with a threaded end for piping smaller than 2 inches
  • 6-8 inches outside the building wall for piping 2 inches and larger if the connection to the meter setting will be threaded, and
  • 10 inches outside the building wall for piping 2 inches and larger if the connection to the meter setting will be welded.

Fuel lines that will be tied into large volume meter settings should terminate 18 inches above finished grade. The meter setting size will be determined by our New Business Team during the application process.

All fuel line piping must be sealed, to be rain and insect resistant.

Meter protection will be required, if near vehicular traffic.  Customer will be responsible for installing meter protection prior to meter installation for commercial properties.

On multiple meter installations, each fuel line stub must be plainly and properly identified with a weatherproof tag or other approved means of designating the apartment, unit or the part of the building it supplies.

Customer Charges:

The first inspection and/or test is done at no charge.  If a Columbia Gas Field Technician determines that a return trip is necessary due to the failure to comply with the requirements detailed above, a tag will be left at the premise stating the reason and the appropriate fee will be charged for each subsequent return trip. 

The provisions in this document are subject to change and are not intended to be all-inclusive. Local codes, ordinances, and governmental regulations will govern when they are more stringent than the requirements contained herein. When in doubt as to the proper procedure, consult your Gas Company before proceeding with the work.
