Here is what I did with the Ball type float. The stock setup does not work well because the tubing is forced to point upward as it hangs below the ball. I added a SS Tee and then used wire to keep it a certain distance down from the ball. This keeps the open ends a good bit away from the surface.
One positive I have noticed with this setup is in the process of keg purging. If you set the length of the tubing correctly, one end of the Tee will fall down into the depression at the bottom of the keg. This helps get all of the sanitizer out when pushing with CO2.
Hope this helps!
