If you fill it completely with water, the fumes have to leave. This sort of stuff is done all the time in the chemical industry where vessels hold thousands of cubic feet of highly flammable materials. When they begin leaking due to the corrosiveness of material or metal fatigue or whatever, they are purged, then welded from the inside and outside to insure a full penetration weld. This is a common procedure.
