How to get an oval shaped copper pipe round again to install compression fitting

How often do

I had a main valve fail once during a major plumbing job, it allowed the basement to flood.

given my unhappy experience a new quarter turn ball valve is a excellent idea.

some things are best not repaired but replaced. that valve is one on my short list:)

Doesn't it require a 5-sided socket, or something else most people don't have? How do you do it?

many people have those tools, they are pretty common but vary regionally. a plumber told me in the pittsburgh area there are about 5 models.

Thanks to all!!! Really!!! You guys are very helpful and very knowledgeable persons.

So what did you end up doing?

Yes, the clamp part of a flare tool can be useful.

For out of round fittings, stick brazing often can fill some larger gaps.

The copper coming up from the lower level had a 20 degree bend so I cut it in the straightest looking area. The compression nut or sleeve would not go on. I saw your post and tried it and it was perfectly round again!!!! I had the whole building water off and this fitting was my shut off taps. Thank you so much for this post.
