My wash is shut down due to cold weather. I stopped by today just to check on things and my flojet for the FB is periodically pulsing. Does this mean one of my solenoids is leaking or hung open?
What you could do is install a ¼” solenoid valve on the air line going to the Flo-Jet pump and build a relay bank to control the solenoid valve. For a 4 bay car wash a relay bank would be simple to build.
