On their own online schematic, Weber calls it a water pan.Originally posted by Dave Wr.:
...I just called the service department and they said this refers to the "water bowl"! I asked her 3 times are you sure - she said yup - the water bowl/pan...
I foiled my 22.5 waterpan yesterday with 2 sheets of foil, the wide aluminum foil won't cover it in one sheet. I suspect water was boiling up behind the alum foil and was leaking over the sides of the water pan onto the charcoal. It also left quite a burned mess on the bottom of my water pan. I was previously very careful to crimp the foil tight against the pan
