Chimney leaking and flooding
I am having a problem with the chimney for my woodstove. The woodstove is located in the basement with a pipe from the stove to the wall, through about 12" long horizontal flue, and opening into the chimney. Over the last year or so when it rains heavily, water fills up the inside of the base of the chimney flue and when it reaches the level of the horizontal flue in the wall (only about 4 inches), it will spill down the wall around the pipe (and come through the pipe into the woodstove itself). The last time it filled my wet/dry vac so it is quite a bit of water. Last summer I dug out around the base of the chimney looking for a crack. I found a small gap between the chimney and the house so I patched it but it hasn't helped. The water does seem to be rising inside the chimney and not flowing down from the top (I have a chimney cap on top). We've lived in the house for about 20 years but this has been happening just over the last year or two. Any suggestions would be greatly appreciated.
