Just got mine set up this morning. I got the 100gpd unit and without a booster pump I'm getting about 50gpd output which is plenty for me, but a little less than I was expecting. I'll have to see if I can hunt down a pressure gauge to throw on the supply line and see where I'm at, I imagine my pressure is a little lower than I thought. The waste:product ratio I'm getting is 5:1, which is in line with the bigger units I've had before, so that doesn't seem too bad. For the amount of water I'll be making (maybe 10-15g/month), I don't know if the improved efficiency of the booster pump would be worth it in the long run for me, but I'm interested to see your results Andre.
