cutting gas line


in our new kitchen layout- we no longer need the gas line that went up thru the attic that fed the old oven. I can trace it back to the basement and cap it off there (or put a valve)- I would shut off the house main gas- let it bleed for a bit- etc- Best way to cut I'm guessing is a hacksaw? I'd be a little weary about using a sawzall....

Why cut it? A few pipe wrenches at the joints and twist.

I've found a pipe cutter useful to cut pipe. Your friendly rental will have one. If you decide to put a valve at the termination, install a plug in the valve. I'd probably choose a cap to lessen the chance of a leak.

We don't have many details of the pipe lay out so unless there is a union somewhere in the length you are wanting to abandon you will need to unscrew every joint until you get to the end where you want to cap it off. Otherwise cut, unscrew the stub and cap.

This is why you need (2) pipe wrenches, one to pull and the other to push, the forces stay local to the connection you are working on.

I had the same concern too when I replaced my gas water heater.

What I did was to apply 2 masking tape sections for 2 joints prior to the section I was working on and drew a straight line. That way, if I accidentally disturbed other pipes, I would see it right away.



I also do the soap bubble test to be sure.

Good luck

Sawzall. Wouldn't even think twice about it after the gas was shut off and bled out.

cutting gas line


is there any "test" that can be done to insure all the gas is out of the line (or do you never really get all the gas out 100% of the time)

if you have a gas water heater, check to see if the pilot light goes out after awhile.

otherwise, i believe pros use inert nitrogen gas to flush out the pipes.

Still at a loss as to why you want to cut the line....it's pretty hard to cap a gas line that is not threaded.

I would just remove the pipes one at a time....then you end up with some spare pipe you can use later.

" I knew a guy who used to check his pipe jobs like that after he was finished". Not Kidding.
