In the past I have usually found one in the front yard close to a
hydrant but not here. I know I could cut the water off at the water
meter if I had a key to unlock the box but I don't.


Do you have a crawlspace or basement or is the
house built on a slab. If the former there should
be a valve where the pipe enters crawlspace or
basement. If the former there is possibly one
near where the pipe reaches the house.
