Well I bottled the brew, all seems to be fine.
However, upon further investigation into the inadequate seal, I have noticed that either the fermenter or the fermenter lids thread is a bit off, the lid will screw in fine until a certain point and then it *clicks* and one side is a quite bit higher than the other which stops it from sealing.
I noticed it when I first started the brew but didn't want to play with it due to the fact there was a brew starting :D
Is there a known problem with the fermenter or am I just the unlucky one? 8)
