However, further inspection on the second floor revealed that a large whirlpool-type tub had been installed very near the wall below. When filled with water, total weight of the tub was about 2,000 pounds. The initial conclusion then had to be changed. Someone had made a mistake during the design process. The wall was in fact acting as (and was necessary as) an important support even though such support was not intended by the floor truss designer. The only way to safely remove this support wall would be to; (1) Remove the whirlpool bath on second floor, or (2) Perform extensive remedial work to reinforce the second floor framing, such as installation of a header beam.
