Well today while i was caulking the wall thimble something struck my eye. The 90 degree is sitting flush on the back of the pipe, but eleveated about 1/4 to 3/16 of a inch in the front. I did not see this before. There is plent of sealent in there, as it ozzed out during the installation. Do you all think this is okay, cause i have no idea how I would get this apart. When selkirk sent me new pipe, I had to cut the old stuff apart.
