Pump question

[ryguylears]

I want to setup my RODI and sump below my tank in the basement. Is there a way i can plumb it all so my external pump to mix my water can also be used as the return from my sump?

I need to get a decent external pump with 12ft of head to get it back up to my tank, was hoping I would only need one.

No. You want your RO/Di water separated from your tank water. No way to do that with one pump. You should set up the RO/Di to discharge into a large trashcan or some other good-sized reservoir. Having it make small batches will wear out your membrane faster. Make as much water as you can at one time. You can put a small submersible pump in the trash can with plumbing to where you will need it such as an ATO or direct to the tank if that is what you want.

That helps, thank you.
