The second floor of a building is empty. It's blocked. Who should I call?

No one lives on the second floor and the water pipe is blocked. That's only for people in your unit. Because it's the only way, right? They can. Not here. The second floor is still not for sale. The water main is blocked. Only your residents on the third floor want to call the property. Everyone in the unit should take full responsibility. The money used to clean the pipes. A unit should be divided equally.
