Hi My name is bill I am 48 years old I live in Bradford Pa. I am new to smoking my children bought me a Char-Broil vertical charcoal smoker. I did a Brisket last weekend and it turned out great. Today I am doing a Pork loin. I have noticed I can't get my heat over 175 deg with water in my water pan. but if I take the water out I can. Any suggestions??
