adding valve to existing line

[gjxj]

I'm looking to add a valve to a 3/4 copper line. My trouble is, although i have plenty of room to work I cant readily move the ends of the line. That means obviously when i cut the line i wont be able to pull the ends apart far enough to install the sweat valve.

My current thought is to cut out about a two foot section. Install the valve, then use four 90 degree elbows to offset a section of the pipe so It can be assembled and soldered together without any stress.

If that a reasonable thing to do? Any better ideas?

They came out recently with these really cool fittings called slip couplings or coupling w/o stop. Comes in handy for your situation.

Thanks, that's what i wanted to hear. Now that i know what to look for I see you can get pretty long "repair couplings" as well, which might be good to have on hand in case i dont get the pipe cut to the exact length needed.

you can turn a dimpled coupling into a slip coupling with a file or a dremel

just knock the dimple down
