    I have a question regarding the water supply to the RO/DI unit. I was thinking of getting a 50gal bucket to store unfiltered water to bring it up to the temp that is recommended for the RO/DI unit "think its like 60 or 70f" from there I have a spair well pump we keep incase our pump dies that will provide the pressure for the unit. my question is can I just put the waste line from the unit back into the 50gal bucket to be recycled and refiltered? or should it just be exactly that waste water. let me know if this is another one of my crazy ideas!

    the "red line" is waste water coming off you ro/di unit... it means waste .
    DO NOT mix your clean purified water with the waste.


    or your on a "refillible" well ? , yes i should see no reason why you couldint put it back in your well to run thrue the ro/di unit over again.
    the ro/di unit works under pressure any way , water that makes it past the filters with out being filtered only go's to waste, in your case though , your able to retreive actualy ( really saves wasted unfiltered water consumption )

    What little added output through the membrane is not worth all the trouble really . You may get a extra 2 gallons a day. The warmer water say 70 just expands the pores in the Membrane I say the smaller the pores the better the water ..You would be betteroff on a well pump to just turn the pressure switch down a couple of turns to raise the feed pressure.

    well the temp makes since but the waste water would take a number on my septic, here is a diagram of what I was thinking. I almost have everything I need to make this happen anyways.
