Well my electric ball valve finally went out after several months without rinsing. It was a simple setup, but flawed because when I wasn’t pulling soap I would lose flow. I had a single electric valve inline between the injector and the house wash. It also had SH in it 100% of the time.
So now I plan to build it out correctly this time and could use some extra eyes before I pull the trigger and order this stuff. The electric ball valves I selected will open or close based on polarity. With this option I can stick to one channel. Check out the flow chart and parts list. Does this look like a solid plan?
