R/O System Questions?

[subman]

We bought an RO system to put under the sink and it has a faucet that goes in the sink. Well I never installed it then we moved and our new house has granite counter tops and I can't put it in the sink. Any way I thought perfect opportunity to use it for my tanks. Now I put it in the basement and I'm questioning how I installed it, The original kit uses the faucet and a pressure tank that I'm not using. After I hooked it up as I figured I should the water is just pouring out of the good water and very little out of the waste water. I always thought it was the opposite or is that just with RO/DI systems?
