I've got an SS half barrel conical and it leaks when I transfer around the lid. I can never get more than a pound of pressure into it to get it to transfer and it supposed to be able to take 3. It leaks around the seal at the lid. Today I came home after brewing yesterday and there was beer all over the floor. As well as going out the inch blow of the inch blow off tube on top also leaked around the lid though the blow off tube wasn't impinge or stuck with anything. I'm guessing I need a new ring inside the lid, but I've only had this thing since fall and not used it much but it doesn't seem to hold to be able to hold 3#. Thoughts? Fixes?
