I got the same filter you have now I don't think I'll have it installed as it wastes so much water and that costs money here.

Isn't Water Wasted Down The Drain With R.O. Systems?
There is a certain percentage of water from the system that goes to the drain. This water is carrying away the impurities. These particles are too small to be caught by the filters. Premier has an automatic shut-off valve that shuts off the flow of water to the drain when the holding tank is full. This valve stops the R.O. system from continuously running water down the drain, thus conserving water via the R.O. system working only according to usage. What Is The Ratio Of Wastewater To The Pure Water Produced By A Premier R.O. Unit? Can This Water Be Saved And Used?
The typical ratio is 4 to 1, based on incoming water temperature and pressure.
Yes. Most wastewater today is recycled for golf courses and artificial lakes. The drain water is slightly higher in TDS concentration than the incoming water, but as R.O. does not add anything to the water, it can be used to water your lawn or garden.
