I live in a four apartment building that was originally a residential home that was converted into apartments. Two story building I'm on the second floor and this morning I experienced a complete loss of water in the entire apartment. The other three apartments have working water. There are a total of six water pipes or lines with shut off valves in the cellar, 4 for the apartments and 2 for the laundry room, mine being dead smack in the middle of the others. The bill has been paid, the valves are all on, there is no water main break anywhere in the town and there is water flowing out of the pipe in the cellar but no water in the apartment. My landlord thinks there's a possibility that my pipe is frozen in the middle of the building. My question would be if my pipe is in the center of these other ones is it possible for just mine to freeze in the middle of the building and no one else's to cause complete water loss. And if not what else might cause just my water to be stopped.

It's possible the pipe is frozen , did the landlord say it has happened before

Is the building on just 1 water heater or individual heaters I find it hard to believe that both hot and cold froze at the same time unless there's a nasty draft in the middle of the building

He said it has never happened before! He even called the previous owner who originally built the house and he said none of the pipes had ever frozen before and then told him where it would go up in the middle of the house- behind which wall

Individual heaters in each apartment. And I said exactly the same thing as far as the hot and the cold both at the same time. Plus I would have expected some type of warning like sputtering water or something to that effect. Is it possible maybe that it's an air pocket?

I would start by cutting above the cold valve that supplies your apt then open the valve and see if you have pressure there, if pressure is there keep cutting every 10' or so and open the valve till you get no water
