I finally made my BMBF bottle filler and I love it. I'm filling my bottles straight from the tap. I got the idea after seeing a video by Joe Fisher on YouTube (sorry, I don't know how to post YT vids on here
EDIT: Nevermind, I see the site does it automagically!

I don't know if Joe is a member here or not, but the only difference I have is I have the 525ss. I think Joe's taps have a screw on bottle filler while mine uses two red Orings to hold the filler in place. Mine fits, to me, real loose in the tap too. I have to hold the filler to the tap with one hand while working the BMBF with the other hand to keep beer from shooting all over the place.
For those with the 525ss, what was your work around? I thought about just getting a short piece of tubing from HD or Lowe's that would fit over the tap and filler and use a couple of stainless clamps to hold them in place. It's sort of the same method Revvy uses with the bottle wand and bottling bucket.
