Yes,either valve will shut water off to house,just turn so holes in ears line up. There is another in a box near foundation of house,look around outdoor hydrant nearest valves in picture.

Awesome thank you! Looked up a bunch of guides on water main types and nothing had this type listed, just wanted to make sure.

Richard:

And good for you for finding out where the main shutoff is when it's not a panic situation. Been there; it's not pleasant and cost me 20K in 10 minutes.

Sorry to hear that Joseph and if it's true misery loves company, you have company. A client called me one Christmas Morning in panic. His down stairs renter awoke to water pouring from ceilings and utility company didn't consider it their problem so didn't send anyone out to cut water off. The renter up stairs had turned central heat off before leaving on vacation, water lines running through attic froze and burst multiple places drenching both apartments. The upstairs tenant was with SMU School Of Music and Dallas Symphony Orchestra so he had instruments in the apartment. I never heard how much total damage was done but an organ appraised for more than I paid for my house 3 0r 4 years earlier was ruined . From time utility was called until I arrived was over 2 hours so as you pointed out,if water had been quickly cut off it would have saved tenants and landlord a great amount of damage.
