Hey Edwin I posted on here before as I too was looking right a system. I make 20 gallons a week as well. I bought the one for brs 150g a Day water saver. Tbh I posted on here and asked around because it seemed too easy to setup and thought I mightve done something wrong. Right now I make 5g jug in 40-45mins depends on time of the day. Reason why I bought this system is when I move in the future and upgrade to a larger system im already set. Not sure if u guys buy drinking water or not, but I unplug the line before the di and makes great ro drinking water. Going to add a t valve when I have time. If u have anymore questions pm me
