How long should it typically take to install a new 20 foot interior gas line?

Answer: Not sure
Explanation: Well, it depends on a number of things. Does it include removal of old piping, or prep work? Is it a flanged connection, Or is there a tie-in? Is there offsets or rolling offsets? Am I working alone? Is the system under pressure? Providing a timeframe without knowing these things would be guess at best, and not accurate.

Answer: Not sure
Explanation: Every job is different . Can not estimate without a visual inspection.

Answer: Two to four hours
Explanation: Being sight unseen it is hard to judge the length of of time this job would take. I would say its safe to say 2-4 hours. It could vary depending access issues and what it will actually take to get to the pipe that needs to be replaced safely.

Answer: One to two hours
Explanation: All sections of pipe to be measured, cut, threaded and hung with a necessary shut-off valve. If proper sizing allows, an installer can easily get the required volume of gas from a branch line close to another appliance by disassembly of the drop to that appliance at the union. If cutting into an existing line is necessary, the job could take to the latter part of the estimated time frame. Turning the gas back on, leak checking, leak testing with pressure test, and lighting pilots on all the appliances should all be done within two hours without rushing through it. The time frame of two hours does not include inspection appointments. So the gas line, although installed in this time frame, cannot be used until inspected.
