The procon pump loses 1 psi for each additional bay that uses the foam brush. The pressure to the bays drops by 6 psi for each additional bay, even though it should drop by 1 to 2 psi. The settings are: 60 psi at the procon pump, 40 psi to the bays, 30 psi air. I replaced the procon pump, the pressure regulator for the pump, the liquid regulator to the bays, the motor, and the check valve to the liquid regulator.
Any suggestions would be appreciated.
