Why not just clean with 000
Because it is not necessary to get perfect results. If I changed my resin as soon as it reached 001 then it would cost me a lot more.
Not if you use two resin containers.
Firstly, it would save you money as you'd get 100% out of all your resin.
Secondly, once you've made that saving, five minutes thought will tell you that you don't save a single penny from then on by letting TDS rise a single point
O
Perfect Windows Prob me being dumb but how having 2 containers would you get you 100% By the way when my tds gets to 001 i change resin
Not dumb at all, but you will need to concentrate.
Let's say water is coming out of your RO at 20ppm.
If you have one container and you work to a max of, say 5ppm, then as soon as it gets to 5ppm, you change the contents.
If you have two then you have RO then container 1 and container 2. As soon as water comes out at 5ppm you move container 2 into position 1, put fresh resin into the old container 1 and put it in position 2. The batch of resin now in the new container 1 is still useful rather than being in the bin, as it's bringing the water down from 20 to 5, thus extending the life of the fresh resin in container 2. It carries on doing useful work up to the point where it's going into container 1 at 20ppm and coming out the same.
Thus, you're getting much more life out of your resin. There's an initial cost, but from that point on it's saving you cash.
Once it's running, as you're getting full use out of the resin, it doesn't save a single penny letting the output go up before swapping over the resin.
Hope that clarifies...
