Safety first

Smell gas near a gas line or appliance? Leave first

Natural gas has no smell of its own. A pungent odorant, similar to rotten eggs, is added before it reaches the pipes in your area. Treat that smell as an emergency, not a project.

Gas smell

A rotten-egg odor near a gas appliance or line.

  1. Leave now

    Get everyone, pets included, out of the building. Do not stop for belongings.

  2. Avoid anything that could spark

    No light switches, appliances, doorbell or flames, and do not start a vehicle in an attached garage.

  3. Call 911, then your gas utility

    Call from a safe distance. The gas utility's number is on your gas bill.

  4. Stay out until told it is safe

    Wait for responders or the gas utility. Do not look for the leak or try to fix it; repairs come afterward.

Common projects

Gas line projects a plumber handles

Most calls fall into a handful of jobs. The difference is what the line has to reach and what it has to carry.

Range or cooktop

A new gas range, a switch from electric, or a move to a different wall. The line has to reach the new spot.

Gas dryer

Adding a dryer connection, or moving the laundry area.

Water heater

A new or different gas water heater can change what the line has to carry. See the section below on heaters.

Grill or fire pit

An outdoor line from the house to a patio. It runs outside, and often underground.

Standby generator

A gas-fueled generator needs its own supply, sized for what it burns.

Repair or replacement of old piping

Worn, corroded or modified piping, or a line that was changed over the years.

Planned work only. Gas piping and appliance connections are work for a plumber. This page gives no steps for doing any of it yourself.

How the work goes

What a plumber checks on a gas line job

This is a general outline. The plumber will explain the steps for your job.

  1. Look at what is there

    The existing piping, where it runs, what it feeds today, and what you want to add or move.

  2. Size the line for the load

    A line has to carry enough gas for every appliance on it at the same time. Adding a range, a heater or a generator can mean the old line is no longer big enough. A plumber works this out; this page gives no sizes.

  3. Run, connect and secure the piping

    New pipe is routed to the appliance, through walls, floors or outdoors, and fastened and protected as the job requires.

  4. Test before it goes into service

    The line is tested for leaks before it goes into service, and appliances are checked once they are connected.

  5. Inspection, where required

    If the work needs a permit, the city may inspect it. See the next section.

Permit and inspection

Does gas line work need a permit?

The City of Greeley says an owner or authorized agent must first get a permit from the building official to alter or repair a building, and to install or modify gas, mechanical or plumbing systems that its adopted code regulates. The city's page does not say how that applies to a particular gas job, and this page cannot either.

Have the contractor confirm permit details with the City's building inspection division, a city department. Plumbing permits in Greeley

Outdoor and underground runs

Gas lines to a grill, fire pit or detached garage

A line that leaves the house and runs through the yard is buried, so locating what is already underground comes first. Colorado law says to contact the statewide utility-locate service (call 811 before digging) at least three business days before you dig, regardless of project size. Ask who will make the request.

Outdoor gas lines also have to survive weather, the mower and the next landscaping project. Where the line will run and how deep are questions for the plumber.

New heater, same gas line?

Gas supply for a new or different water heater

A water heater is one of the larger gas users in a house. Changing it can change what the line has to supply.

Swapping like for like

  • The same size tank-type heater often fits the existing line
  • A plumber still looks at the connection, venting and condition of the piping

See water heater repair and water heater replacement.

Changing the type of heater

  • A tankless unit can use more gas at once than a tank-type heater
  • The line, and sometimes the venting, may need to change

See tankless water heaters for what a retrofit changes.

Before you call

What to have ready

A short description of the project lets the plumber tell you what to plan for.

Tell the plumber

  • What the gas line is for: a range, dryer, heater, grill, generator or a repair
  • Where the appliance is going, and how far that is from the existing gas piping
  • Whether the appliance is new or being moved, and its label or model if you have it
  • Whether the line will run outdoors or underground
  • Any earlier work or problems with the line or the appliance

FAQ

Gas line repair and installation in Greeley: common questions

What should I do if I smell gas?

Leave the building and take everyone, pets included. Avoid switches, flames and starting a vehicle. Call 911 from a safe distance, then your gas utility, whose number is on your gas bill. A plumber is for repairs after the area has been made safe. See emergency plumber.

Does gas line work need a permit in Greeley?

The City of Greeley says a permit from the building official is required first to install or modify gas, mechanical or plumbing systems that its adopted code regulates. The city's page does not say how that applies to a particular job. Have the contractor confirm permit details with the City's building inspection division.

Can I add a gas line for a range or a grill?

Often yes, but it depends on the existing piping, how much gas it can carry and where the new appliance goes. A plumber looks at the line and tells you what the project involves.

Will a new water heater need a bigger gas line?

Sometimes. A like-for-like tank swap often does not. A tankless unit can need more gas at once, so the line may have to change. See tankless water heaters.

Do I need to call before digging for an outdoor gas line?

Colorado law says to contact the statewide utility-locate service (call 811 before digging) at least three business days before you dig, regardless of project size. Ask the plumber who will make the request.

How is a gas line job evaluated on site?

A plumber looks at what the appliance needs, the size and route of the existing piping, and where the new line would run, then explains the sizing, the testing before the line goes into service and the permit question for your job.
