I live on a second floor of 4 story apartments building and I'm planning to change my old washer+dryer tower for a new one, however it is bigger and heavier. I'm worried that the weight could cause a problem.
The new weight will be 315 lbs (I believe the previous one was around 255 lbs). I do see that new towers are around this size and weight, so I suppose it should be ok, but not sure about the max weight that buildings are supposed to handle.
