Gas Piping

Gas Piping

Heavy black iron is the typical material used when making gas piping. It is important to have your gas piping installed by a professional rather than attempting to install it yourself. It is also wise to have your gas piping services by a professional as well. It can be very dangerous to work with gas piping if you do not know what you’re doing.

You can use flexible gas piping for special circumstances. An example of such a situation would be when connecting a valve to an appliance such as a gas dryer. Flexible piping typically cannot be longer than 24 inches (2 feet), and you do not want to conceal a union. It is also vital that you make sure there are no leaks; no guessing or assuming with this for your own safety.

Alterations to your gas piping can require a local building permit, so make sure you have one before touching it.

When a professional checks your piping, they look at:

  • Controls
  • Regulators
  • Gas tank defects

If you smell gas:

  • Do not light a match or even operate a telephone or electrical switch. Doing so can cause an explosion.
  • Leave your home or building right away.
  • Immediately notify others in the building if it is a multi-unit.
  • Contact your local fire department and gas company, and inform them of the leak.

Reasons you may smell gas & what professionals look for:

  • There is a leak in the gas piping – A professional will look at piping joints and areas of the piping for corrosion or pin holing.
  • Meter equipment leak – Meter seems and piping connections will be checked.
  • Control valve leak – They will look for a leak at the pilot and temperature control knobs. They will also look at the center seam on the right side of the control.
  • Gas line shutoff – These are generally located at the main gas meter. There may be another shutoff in the sidewalk or street outside of the building. A shutoff is open when in the down position, or when it is parallel to the pipe.
  • Pilot line at the control of the appliance
