^^^This was a "doh" moment for me! Have a bottling bucket sitting unused since I am kegging, but now it is my new fermenting bucket!
Here are a few tips I posted in a similar thread a while back:
*Make sure to keep that spigot clean. Take it completely apart - the valve comes out. I assemble it into the fermenter while submerged in star san.
*I use seal rings on inside and out. after assembling and putting the spigot in the bucket, take it out with a gallon or two of star san in it to make sure it is not leaking. They will leak a bit sometimes. That way you can adjust it and make sure it is not dripping at all before you put your beer in it.
*Keep spigot twisted a bit to the side - not up and down. Often the spigot will actually sit a bit lower than the bottom of the bucket. You don't want it resting on the spigot - it will break or leak.
*I put a sandwich bag with a rubber band over the spigot to keep dust, fruitflies, debris out of it while fermenting.
* I keep star san in a spray bottle and spray it out well before opening spigot for samples or transfer.
*Take the airlock out before opening the spigot or it will suck back into fermenter.
*Set it up on counter a couple days before you want to transfer - that way it allows any yeast/trub to settle back after moving.
Basically, I think they are absolutely great fermenters - no siphoning, easy transfers, there is enough dead space for trub and yeast to settle below valve. Also a great way to collect yeast from beers that are rather low hopped and turn out well. After transfer just leave a bit of liquid behind, swirl it up and transfer into clean, sanitized mason jars through the spigot.
Like I said - they worked great for me for 5+ years before I started to use some SS brew buckets. I would use them before any other type of fermenter besides my ss buckets.
