Oh, haha! I thought there was some new fancy schmancy flow restrictor or something. Yes, at the time I bought the 150 gpd membrane, the 150 gpd flow restrictor, and the booster pump. I put that into my AquaFX RO unit. I ran it that way for some months, but I wasn't happy with the amount of waste water which was about 1:4, so I took the 150 gpd restrictor out, and put the 75 gpd restrictor back in. This restricts the output quite a bit, it originally was about 1:1.5 (product:waste) and over some years it's now closer to 1:2 I'm guessing, but the membrane is pretty old now. I haven't actually measured it recently though.
