because you asked, you call a plumber.
he's the one who doesn't break the main.

also: did you finish all your inside repiping?
did you remember make it drainable to be able to easily winterize the
house? did you add all those anti-freeze garden hose valves
conveniently around the outside of the house?
did you use 3/4" pipe and gate valves throughout the home [despite
others advice of 1/2"] to deliver lots of usable water to your
showerheads and sinks?

fill up the tub and extra pitchers for water in the house.
turn off the buried main water shutoff at the street under the water
cover. does it turn off and on? good.
you will be replacing your old indoor main gate valve, and for the
future use put in a second one leaving several working inches of pipe
between the two.
