Extending a gas line
 

My guest house remodel involves moving the stove from one wall to a perpendicular wall about ten feet away. I need about 15 feet of CSST gas line run. I was going to do it myself but the local plumbing supply will only sell CSST to a certified gas plumber. I called a plumber and he is going to charge $500 which includes the materials. Seems pricey but I guess it it will be done right.

I would think the $500 also includes getting a permit.

Google is your friend. Seems pretty easy to get.

Home Depot has flexible gas line. By the time you are into the materials, connectors and the cutting tools (yes, takes a special tubing cutter!), you are about 30% the way there. $500 seems like the no hassle way to go.

If you were local, I'd loan you the tools and give you the gas line.

The gas line pressure after the meter is about 1/4 psi, or about 6-7 inches of water. You can run the extension with steel pipe with pipe threads sealed with telflon tape (yellow) and plumbers dope. I pressure test the line to 5 psi and see if it holds and do a soap bubble test on all the joints.

I DYI as much as I can but $500.00 and you have someone to hold responsible? No brainer.

It's a gas line not a water line.

I just could not figure out how to get black pipe between 16 inch spaced studs without a bunch of couplings.
I thought about ordering the pipe and fittings from Home Depot but it’s over 30 miles away and not sure the fittings are the ones I need.

Just don't let them see the Porsche or it will be $1,000.

My thoughts exactly.

Another vote to have a pro do it. Flexible line on a gas line is restricted to a certain length in many cities codes. Be sure the pro has a city permit for the work. When the day comes to sell the house, you will be happy a licensed pro did it, with a permit.

One of my friends of a friend has an offer on a house. It was a "flip" house, and the work done by the non professional owner. They have found several horrendous bodges and flat out wrong items. I told them to RUN from that house unless it is 1/2 the price they offered.

This is correct

ok,

I see the problem. You could try copper but long flexible CCST seems to best way to go if you want to go thru the studs. You can use double male nipples to join two or more lengths together but I wouldn't bury a nipple under drywall. Maybe an inspection panel so you can do a soap bubble or snif test in the future.

Are gas lines like electrical lines where all junctions need to be accessible?

Just look up local codes on flexible gas lines. Around here is is a fairly short line that is permissible. Long runs of flex line are a code violation. They have the codes for a valid reason. You don't want your house leveled by a gas explosion.

On a YouTube there is a contractor doing his entire house with CSST.
