Options if shut off valve is covered up?
I discovered an outside faucet that would be very useful. Nothing comes out of it now, and i can't locate a valve to open it. But I do have a vague recollection of a valve on the wall inside the adjacent room -- that is now completely covered by a built in bookcase! Believe me when I say I can't tear open the bookcase to pursue this hunch. Please tell me what other options I have! Thanks.
