I put a couple of batches on the other day and they started up pretty quick. They're both in plastic fermenters and I used regular old airlocks. After day 1, the airlock on one of the looked like it was spewing a root beer float, so I changed them over to blowoff tubes. That's when I noticed two potential problems on one of them: (1) the tube was slightly smaller than the hole in the bung, so I could hear gas coming out of the gap, and (2) gas started coming out from under the lid of the fermenter.
To fix the first problem, I soaked a paper towel in sanitizer and stuffed it around the tube where it goes into the bung, kinda like a caulk.
For the second problem I tried pushing down on the lid to make it tighter, but it was already all the way down.
So I'm wondering if this is going to cause problems or am I being paranoid? Any comments or suggestions are welcome
