Recently I purchased a Englander 30 to replace my Shanandoah r77E junk stove that I bought 2 years ago. I connected the new stove to the second flue in my 2 flue chimney. This flue had never been used and the chimney is only 2 years old. The chimney has a concrete cap on it. I am very happy with the stove. It seems to heat well and good burn times. The problem is there is an inch or so of water in the cleanout on the chimney the Englander is attached to. We have had quite a bit of snow lately but i never had that problem with the other flue. Is this a common problem or something I should worry about. Thanks for any responses.
