Very straight forward. I used lots of unions in case I need to take things apart . The outputs of each of the of dosing pumps join in to a single line that is connected to the injector part of the venturi injector.I'd definitely like more details as far as the build went and how you inject food from the dosers into the pressurized return line?
The injector part of the venturi naturally creates a suction so as the food is pushed out, it is caught in to the water flow and in to the tank.
