More On F.O.B.s

I have had several calls lately about FOB floats dropping on new kegs.
This reminded me of another aspect that makes the use of FOB's pay for themselves.
When a new keg is hooked on a non FOB system a crack or bad seal on the dip tube can go undetected for an entire keg.
What happens is the supplied gas pressure seeps through the exposed opening allowing turbulence and or foaming.
The FOB will tell you that you have a bad Keg draw tube by acting as if the keg is empty. Every time you bleed off the chamber of the FOB it will appear as if the beer is bleeding back into the keg. what is actually happening is the supplied gas is refilling the FOB chamber letting you know the keg is malfunctioning in some way.
If you find yourself experiencing this problem switch kegs. If this fixes your problem you have saved yourself the hassle of wasting a keg and the aggravation of wondering what is wrong with your system.
