Self Serve Foam Brush Settings

Do you use the right amount of air?

[YangFuMin]

I had this question today as my presoak was spitting air and not enough fluid. I played with the fluid pressure and got the stream working again. My system is 30 years old and the foamy brush and presoak share the same air pressure but they have individual regulators for the fluid pressure. Thanks for the education on this. I'll be checking my floam consistency from now on using your guidelines. (and how come an Aussie has a Scottish accent?)
