No. I thought you might have removed it to clean it and then failed to reattach it properly.Hmm, no I left the tap on when sterilising. I filled it to the brim and left it a day (then cleaned it out). No leaks at that point, so rinsed it out and filled it with beer.
Could the steriliser have damaged the tap?
I didn't notice any smell when making mine but I did cover it with a bin liner and a sleeping bag.Does it make the room smell?
