foam Brush

[aca carwash 2]

Hello everyone its been awhile. I have two self serve bays. one ss bay the foam brush is all liquid, the other bay foam is perfect. they both feed from same pump and same tank. What can be the problem?

I'd start by doing a quick check to make sure the air is leaving the solenoid and arriving to its destination successfully.

I concur. No air to the brush.
