First time home owner, can't find water shut off in condo
EDIT 1: So the white valve is the shut off apparently. The hoa president has the same unit layout as me and we're thinking the shut off valve needs to be replaced as it should be what turns the water off to the unit completely.
Hello! I am a condo owner and I cannot for the life of me find the shut off valve for my unit's water. This is my utility/storage closet and the water heater. I've turned off the two valves that are on top and let my downstairs sink run until it was empty, but it only emptied the hot handle. Running the cold handle still ran water. Am I missing something or is it possible the total shut off valve (like in image 5, which is what I've seen in every other home I've been in) is behind the drywall somewhere?
Thanks for your time and help!
