    I have just ditched my RO and use big DI vessel only as I feel bad about the waste water( my sister lives in Africa so i just feel guilty pouring clean water down drain!) - Is there any point in still using the pre filters ( carbon- sediment) ???
    Thanks for your help

    You must be lucky enough to live in a low tds area , my tds is 380 so I'd never ditch my trusty ro.
    Yes there's a lot of waist from it but I'm still paying for it (I'm on a meter) the waist goes down the drain and straight back to seven trent water treatment plants so all that's waisted really is my own money

    You'd be better off using two DI vessels in sequence. Here's how it works-

    One vessel is filled with fresh resin & the other acts as a pre-filter to it.

    Start initially with one vessel. When this begins to go off i.e. reading 004/5ppm this is when you add the second vessel with fresh resin & use the 00/4/5ppm one to pre-filter it. Ok, the TDS will rise in the old vessel but while ever it's below the normal input TDS it's saving you money. So now instead of throwing away a vessel full of resin which is still purifying water to a good degree, you are using it to pre-filter your new resin.

    Hope that makes sense, this is how most DI only users are set up these days.;)

    Just to add to that- you then continue the cycle with both vessels. When the newer one eventually begins to go off, fill the oldest one with fresh resin & use what was the newer one to pre-filter the now fresh vessel.

    Same as my tap TDS & perfect for a twin DI. I would recommend two 11Ltr vessels.

    So how do you feel about flushing the toilet with perfectly good drinking water....you could use an IBC tank to store this RO waste water and plumb this to your toilet cistern if feel so bad about wasting water ;);).

    Yes with that water tds a ro would be pointless, how much resin a year are you expecting you would use ?

    I already do this myself, it's a great idea and makes the second resin last for ages
