Do draft inducer's work?

[Firefighter4634]

I always had problems with downdrafts in the summer and when the furnace would go out in the wintertime. We had a a 7x11 masonry chimney that was 32' tall. One of the problems was the stack effect, which I had done alot of airsealing in the attic and basement. Even then the basement would stink and when I would remove the flue pipe it felt like a fan in the chimney blowing air into the basement. This summer I installed a 5.5" rigid chimney liner. I now have draft no matter what. I haven't had the chimney reverse one time and I have better response from the furnace. Night and day difference.

Thanks to everyone on here for their input. I think after lots of reading and resaeach seems like the best thing will be to reline the chimney. I know I also had problems once in while getting a good draft, I would have to run the bottom draft door on the stove wide open just to maintain a good fire. Instead of spending around 250.00 dollars on the draft inducer and new chimney cap I think putting that towards a liner for around 430.00 and insualtion for around 200.00 might be better. At least then it is done and should be good for many years.
