Has anyone used one of the aero tank vents on the black water vent? The one I am referring to looks like a wind vane and rotates to catch the wind. Do they work and are there any problems with them? Thanks for your replys. I just saw a new one ( new to me ) that claims to eliminate the use of toilet chemicals with its aero action. I have a 3055 and assume that the black tank vent is the one above the commode room.
