From your original post I really have no idea what you are talking about.
My bad. I'm not at home right now, so I can't post pics yet, but I'll describe it best I can.
I have a copper pipe running along my basement wall. It leads to an exterior tap. I want to install a shutoff valve in that pipe, somewhere along that inside wall.
I'm a beginner, so I don't know which fittings I will be using -- I assumed I would buy a standard straight valve at the hardware store and that it would come with the right fittings.
I'm concerned about what will happen if, when I cut out the section of pipe where the valve will go, I do not cut it exactly the right length.
Hope this clears things up a bit. Thanks for listening.
