Need plumbing help

Depends on where you live. Up here we are responsible from property line. Normally that's where curb stop(valve) is.
Yes all valves need to be closed slowly. It'll cause water hammer. You and other 2 neighbour's could have had that repaired nc. Municipality was at fault there.
A call to Distribution dept is free.
Past meter is all you, bub....found that out when they checked the fire plug and then closed it right at my curb. Sent a shock wave that broke the main into my house under my lawn. 2 other neighbors were affected too...I guess they have to close it very slowly. I was able to dig up, cut and thread the pipe and put PEX from that to my entry point fitting.
