Ask This Old House plumbing and heating expert Richard Trethewey explains how gas piping is installed in a home.

Skill Level: Expert – for licensed professionals only

Steps:
1. In general, residential houses start with 1” gas pipes at the gas meter and then branch out to smaller diameter pipes using T fittings as they reach their appliance destinations.
2. To connect gas appliances to the main branch, there are gas pipes that come in a variety of lengths that you can piece together to reach each appliance. They are secured with pipe dope and gas fittings. Because of the way the threads work, piping always has to start at the source and work its way outward towards each appliance.
3. It’s also possible to thread your own gas pipes at the exact length you need if you have a pipe threading tool.
4. Before turning the gas back on, any professional will test for leaks by connecting a manometer to the pipes, locking in the air pressure, and waiting overnight to see if the pressure drops.
5. If the new gas work passes the manometer, a soap test should also be done as the gas is turned back on. If the soap solution bubbles over any of the new work, that means there is a leak.

Resources:
Richard emphasizes that only a licensed professional should work with gas. The materials they use for gas pipe fittings, including the pipes, nipples, and pipe dope, can be found at home centers and plumbing supply houses.

  2. Having enough volume and pressure being delivered to the appliance means everything with gas. Before I retired in 2016, I worked for the gas utility company in Baltimore. Sometimes we'd have a distribution problem when a large building converted from oil or coal to gas and a larger service pipe was tapped into the main to supply the new heating plant. Occasionally, there would be too much demand on the main between the new and existing customers when the new heating system would cut on and the main pressure would drop too low from insufficient gas volume. We'd then have to do a system reinforcement installation to boost the gas supply requiring either a larger main being laid for the new service or tapping a nearby higher pressure main and installing a pressure regulator station and back feed main tapped into the old main near the customer's service pipe. The same is true with a building having multiple gas appliances – you have to have the correct size pipe so that each appliance gets a sufficient supply of gas volume at the pressure required even when all the appliances are operating at the same time.

  4. you basically learn nothing from this video. it is not a DIY vid and also it doesn't go into detail the purpose of the size of pipe and how it affects pressure. A lot of things left out that would have been nice. lame

  9. The reason they left out a lot of information and used lots of fittings is because they don’t want people dealing with gas pipes. Minor plumbing is one thing but gas pipes usually should be left to a pro if you’ve never done it before.
