Reverse osmosis system recommendations

A positive note is that the system is filtering the water down to 0 ppm total dissolved solids according to my meter.

Do you think if I remove the de-ionizing stage, it will produce at a better ratio, but with an increase in tds? I guess I could try it.

That’s amazing considering your starting point.. I can never get mine below 8 ppm. I think you should tinker and experiment while you are in the mode. Just remember you have to add back to the water, so anything below 20ppm you are still winning the game.

They are just not that efficient at this entry level, if you want a 1:1 ratio, you have to shop for the high efficiency RO systems.

I was wondering how RO systems are legal in CO. Not a knock against you, I know living in the arid west they have laws that prohibit the use of rain barrels and evaporative coolers. I guess RO tech gets by for drinking water purposes. Maybe you can keep some of the discarded water in buckets and use it to flush toilets? Not sure what else you can do with it.

The waste is awful. But then again, have you seen how popular those big fancy car washes are these days? I don't get it either.
I will save as much of the rejected water as I can, especially in summer when I'll (finally!) have an outdoor garden. Using it to flush the toilet is a good idea as this house still has old toilets that use huge amounts with every flush.

May want to look into how safe it is to use on edible plants. I’m not sure what else it’s pulling out that might be harmful. If it’s safe then it would open up more options. You can have fun experimenting watering lawns, shrubs and ornamentals. Cleaning outdoor items.

You should calibrate your meter. 0 ppm is not likely.
Test your discharge water ppm it should be really high

The lower the ppm in the filtered water means more gallons of waste water. There is no need to filter below 20 ppm.
Closing the supply water faucet will lower the pressure and raise the output ppm. And it will decrease the waste.
