When using a blowoff assembly, is there a time when a regular airlock should be used to replace the blowoff? Or if your fermentation pushes through your airlock, should you replace with a fresh airlock? I used a blowoff on my last brew and a lot of crap came through the hose and into the bucket of water. I just left it like that for a week and a half, and when I when I went to transfer it, it smelled really bad. Could the beer in the bucket have been infected and then traveled through the hose to infect the rest of my beer? Thanks.
