self serve low pressure pre soak and tire cleaner

[aca carwash 2]

low pressure tire cleaner and presoak spit air sometimes and a little product sometimes then sometimes nothing.
the pump is working but not sure its getting product. is there a solenoid for air and product? could the air solenoid be bad if its spiting product and air inconsistently?

Not the solenoid, sounds like your air pressure is too high or your liquid pressure is too low.

Thanks MEP I turned up the product pressure. The way the self serve bench was installed its very hard to get to the regulators and gauges.
right against the wall and compressor. ugh
