How to run natural gas line, or how to blow up your home in 3 easy steps.

[Turin39789]

Help wanted, demo is halfway done and electric has been run. Thinking about hiring out the drywall on the wall I knocked down because I'm just lazy and would probably do the mud and tape bad anyway, but I also need to relocate a gas line and I'm thinking about doing that by my lonesome.

Gas line for stove, want to move it to opposite wall 11.5' away. Figure I need to take off the vertical piece and turn the 90 towards the new wall. Then either carefully measure black iron, but am starting to think about just doing the run in flex hose(which is what one plumber quoted over the phone, but don't know if I can just come up through floor with flex or if I need a fitting or pipe to terminate it through the floor.

Smarter and experienced people please educate me.

1. You must obtained a home owner permit for gas work if your town allowed home owner permit.

2. Flex pipes may or may not be purchase by home owner pending the whole sales store.

3. Flex hose are not allow to go through wall or floor, but certain flex pipes that are approved for such application are okay to go through walls & floors.

4. You must have a shut off within reach at the appliance and a regulator may be needed to drop line pressure (if gas line is greater than 14 inch water column).

5. Flex pipe must be install at the middle of the stud or greater than 1.5" from the edge of the stud, other wise you must have metal plates to protect the pipe.

You can terminate the hose at the floor with a flex flare fitting x FIP (female iron pipe threads), and have a short black iron nipple for ease of mounting/securing, and to install a shutoff valve (brass ball valve) & gas regulator if needed.

Appliance BTU rating will also needed as well as the appliance pressure rating in WC (water column) to calculate the needed pressure for the pipe run & matching regulator (inlet pressure, outlet pressure, and BTU).

Good luck!

If you are near a Lowes/HD/hardware store then it is not to hard. I would run hard black pipe myself. You can use flex to connect the appliance.

Use good pipe sealant and test ALL your connections with good leak test. And restest them 1 week or less later after being in use, I have seen some leak after being in use a little while later.

Yea, flex seems easier but I think I will probably just go with black pipe. Spent a long time in the hated crawlspace yesterday, may wait a little bit before I get to work on this, should get it done before tile though.

Gastite is the easiest way to go. A couple plumbers I know around here said they won't waste their time with other stuff. It meets code here, of course. Where it comes through the floor, you have to install some sort of flange (or whatever it's called. It has a special fitting for the gastite to create a leak proof seal. Then, from there, a shutoff valve & the flex line to the appliance. Should take you 20 minutes to install once you have the materials, cheaper than black pipe & easier. Where you purchase the gastite, they should be able to get you everything you need.

Gastite costs more than black iron, and I prefer black iron because it take about the same amount of time for me to install it as gastite because of switching back to black iron for the regulator, shutoff valve, and appliance flex connection.

Simply put: Get some automotive heater hose and some hose clamps. Expand heater hose over gas pipe, remember to put on hose clamp. Turn gas back on. Celebrate by lighting up cigarette.

Use black iron, disconnect the meter and test the system 15psi when you're done.

Gastite appears to be a good product, with a proven track record and code approval. I flat out refuse to use it under any conditions. The material is simply to fragile. One misplaced nail, one screw that's just a bit too long, and you've punctured a gas line in the wall. I'm very fussy about things that can go bang and kill an entire family, and while my fears appear to be entirely without merit, I'll stick with good old fashioned steel.
