als when flushing, turn the fan off in the bathroom. It draws air up from the tank when you flush.
I replaced my toilet with the foot flush this past spring. I also didnt like putting my face close to where I just went.
I really like the foot flush alot better.
Keep an eye on the back of the tank by the valve area and down on the floor,if you get a Thetford. My valve leaked some. I called them and they sent a replacement valve right away. I replaced it and have no problems now with it
