I was hoping to automize an auto top off system, but I can't find away around tds creep that happens when your rodi kicks on.

I don't want to replace di like crazy. So is there a way around this beside a manual inline wye to divert? I've looked for a timed diverter type valve but can't find anything for it.
 
I think you are looking for an automatic flush valve:

I have one of those. That's used to flush your system when using a second membrane that reduces waste water production.

You usually have a manual valve before your resin that you bleed off the high tds. I want to use Auto shutoff all the time, but if I do it like that then when the system clicks on you get an until high tds that will chew through your resin like crazy.

There has to be a diverter valve I can put on a timer or sensor. I just can't find a remedy
