I Have a 6.5 gallon true brew fermenting bucket and the airlock does not go in tight at all. You can push it down with one finger. Is this normal for a lid on this kind of bucket?
all good grommets come in 2 sizes one for s type one for 3piece. I get mine here just makes for snugger fit nothing happens with looser fit (although I prefer as snug as possible for long ferm)
