I saw the video Chris put out on how to foil the water pan. The shape of my new 18.5 WSM required 2 pieces of heavy duty foil. I have also foiled a 14 inch terra cotta saucer and placed it in the water pan. Is there another water pan that I should look for that can replace the one that came with the smoker? I don't want to have to waste using a second piece of foil just to cover the outside of the water pan.
