foam brush

Hi everyone. Does anyone know how I could adjust settings to make the foam brush more foamy? What comes out of it is kinda like what you would see come out of a foaming rain bar. There is lots of suds, but it doesn’t foam up like most foam brushes do. This is in all of our bays. Any recommendations?

Ok guys got a tough one. I've been managing this car wash for a year now. I've worked here for 5 years. Previous manager never fixed the foam brushes and I'd like them to work properly. They get liquid product out to brushes but doesn't foam because they've not had air supply. I'd like to fix...

Just changed over to a new foam soap and it seems to be getting chemical but won’t foam up originally changed the tips till I could get some product out but once I did it wouldn’t foam. I’m new to most things regarding car washes wondering if there’s a simple fix for this issue.
