Too much foam on tri foam

[dustpan]

My tri foam on my water wizard is foaming up so much that the foam is building on the gantry and blocking some of the streams from spraying out on to the car. I?ve tried turning down the air, and diluting down the product, to no avail so far.

Try turning down the pressure on the pumps that supply the polish so there will be less polish going out to the machine. Turning down the air will allow more polish to go to the machine.
