I always use a blow off tube when using my FV as i have had a couple wines come through the airlock (see picture below) they are also useful if you only have a standard airlock and a vigorous fermentation keeps blowing the liquid out.
They are also much quieter than airlocks.
The how to bit -
Cut the bottom off an airlock then get a short piece of syphon tube and soften one end in boiling water, insert the airlock tube leaving enough sticking out to get a good seal in the FV grommet.
Pour enough water or steriliser into a container (i used a small vinegar bottle - see below) so the other end of the tube is just covered and that's it, you can now empty the container if it gets messy which is a lot easier than cleaning airlocks.
I used some blu-tac to seal the top (leaving a small hole) which keeps the end of the tube in place under the water and nasties out.
I saw this mentioned in another thread after i posted the how to above -
You can also use a standard syphon tube if you have one with a tap as the longer side of the tap is a tight fit in the grommet.
I have also seen people push the syphon tube over the inner part of a Wilko handy airlock.
My version
Manxnortons blow off tube in action.
