For those determined to make this a do-it-yourself project, xj. and both post personal accounts of installing a new gas supply line.So installing a gas appliance a short distance from an existing gas line might require 20-50 or more linear feet of pipe, or however much is needed to reach back to the gas manifold. Although it may appear logical to simply extend an existing gas line a few feet to where you want to add a gas dryer or a gas barbecue, often it's necessary to install a T-valve back at the gas manifold and run a new line all the way to the new appliance, or to replace the existing line with larger pipe. Gas pipe must be correctly sized according to how many appliances are on the line, and how much gas each appliance needs to function properly.Related articles: Dryer Vent Installation, Plumber, Gas Central Heating, Replacing a Water Heater, Furnace And in areas with higher labor costs, a long and complex installation project could be $800-$1,000 or more. If not, running a new line from the gas manifold (where the gas service to your house starts) to where you want the new appliance installed might take 20-30 linear feet or more, which works out to $300-$750. Extending an existing gas line 10 feet might run $150-$250, but that can only be done if the existing pipe has the capacity to add another gas appliance. In estimating the cost having a new gas line professionally installed, expect to pay $15-$25 a linear foot to hire someone to handle everything - labor, materials, testing and any required permits - and there's often a minimum charge of at least $100.

Because of the danger of leaks or an explosion plus the liability involved, most experts recommend hiring a certified plumber or contractor to install a new gas line.

It's possible to add a gas line as a do-it-yourself project for $50-$150 worth of materials, but in some states certain types of flexible pipe or other special materials can only be bought by someone officially certified to install them.

In some areas gas companies charge less than certified plumbers for installing a gas line in other regions the gas company may charge as much as twice the going rate and not all gas companies have technicians available to install an additional gas line. If this service isn't free, your gas company may install the line at a set rate, then add the charges to your gas bill and let you make monthly payments.

Some local gas companies will install a new gas line for free if you're adding a gas heater or a gas water heater plus another gas appliance such as a dryer or stove.
