This Pressure Vacuum Breaker is between the city meter and the house. Usually when the layout is this way. If I shut these two valves off, does it stop the supply of water to the sprinkler system or the entire house?

    it should only be for the irrigation system. you should have a backflow preventer inside your house.

Normally I would expect it to be for the sprinkler system but you never know. There is a valve on it, turn it off and then try the faucets etc in your home. If they quit it is a main cutoff, if they keep working it is for the sprinklers which at this point with the valve off they will not work.
