Hi,

The old main valve of my house doesn't stop the water flow very
tightly when shut off. I need to install a new main valve. It's on

Why?

3/4" copper pipe. I'll install the new valve just over the old one.

Over??

The problem is that the old pipe is now more oval in shape than round
and I'm afraid that the joint will leak. I planned to use a
compression fitting, since the old valve, when closed, lets pass
enough water to prevent us using soldering.

Is there a way to get the pipe round again?

Can't you rebuild the current valve? �Turn off the water at the
street, and change the washer and/or the stem and whatever else needs
changing on the current valve

Best regards,

mm: I meant "above" (not "over". Sorry)

It's true that we could rebuild the current valve. It will probably
fail again soon or later though (unlike a ball valve).

Doesn't it depend on how much later later is.

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
