I think I've got the Wife convinced to let me buy a Brush, and some extentions to sweep our chimney.....gotta admit, I told her "I've seen it down, heck I can do that !!", but I'm a little concerned that I might do something wrong and mess up. I'm particulary worried about the Flue when I run the Brush thru it....afriad I might seperate the sections (if there are any.....wasn't here to see the install into the Chimney)....or worse....lose the brush half way down.....I have nightmares of pulling up the rods with no Brush. So, just how easy is it ???....is it as simple as just running the brush up and down a few times ???....should I have a wieght with a rope tied to the bottom of the Brush in case I need to pull it from the bottom ???....I intend to do it from the top (even though I'm not thrilled with hieghts).....Thanks for any tips, and reassurance.
