ok the drain water(bad water) has a flow regulator should this be all the way open ?
Ro/di Unit Question

I believe it should be closed (causing pressure threw the membrane) for making RO water and open to flush/clean the R/O membrane

Is this the valve you're talking about? You need to have some kind of back-pressure so the water will be forced through the membrane. Some do it by valve others do it with just a collar.
If there was no pressure than the water would flow right over the membrane and down the drain.

That valve in the picture is not on your drain (waste) water line though is it?

Yep. right too the house drain! If you open that valve up you are just flowing water through the system and effectively running water "over" the membrane not into it. This is to flush the membrane off to further life span. When its closed it forces water into the membrane and what isn't pushed in goes to the drain. Higher rated RO units make less waste b/c more water passes through them meaning less goes down the drain. Where lesser rated unit take more time to create water b/c less passes through the membrane thus more waste......

awesome yes that was the thing i was talking about.
wish these things came with better instructions!

Not sure how much/many times you're supposed to flush the membrane. I just do it for a couple of mins evertime I make SW...........

mine says it makes100gallons per day. so i am just going to let it stay on and fill up big blue tubs!

It must be a different type of system than mine. My waste water line has no valve, and if I were to close it off, everything would just back up, not allowing waste water to escape. Maybe my pressure valve is before the membrane.
It probably has a small collar on the inside of the waste line. You can retro fit these flush valves b/c it allows to flush the membrane. I think they have some on the bay.......
