Question Main water valve replacement


I really want to do this job myself but I need some guidance. This is the original water valve aging about 65 years old and it's leaking now. I did some research and all suggestions point to replace it with a brass full port ball valve. My question is what type of tools do I need to complete this job and how do I remove it without busting the other pipes? See image below.

My opinion?

Leave it if it aint broke..

Whats that valve for?

But if you must change it I would not want to turn anything out but the valve off the main..

I would.

1. loosen union
2. cit off stem valve body with sawzall. ( so you can turn out with wall there)
3. cut top of valve nipple off with saw zall.
4. Turn off valve off main pipe. Be very careful as to hold back and not crunch, twist pipe in ground. You will have issues if its steel and rusted down below..
5. turn out top nipple and union piece from tee.

Then buy new threaded valve, union, and same nipple sizes you cut out..

You may need longer or shorter nipples due to the fact the new valve may be a different size.

The trouble will be getting all the parts back in there and lining up the union.. You will see that the whole new assemble is too long but when you make it up it will get shorter so the union mates together..

If you have play in the bottom pipe it will be easier..

If not turning that tee out slightly, assemble it all, and turn the tee back to mate union..
