Can you ever get it all out ?

I've been doing the acid bath and alk wash getting ready to put the membranes away.

So I'm looking at the perm in the stock tank and trying to figure if I can do all the flushing with what I've got left. And I look at the plumbing circuit and realize that there's not much going on but sending 25 gallons in ever widening circles. Every time the solution goes around only some goes down the drain and lots keeps going in our "recirculation ciruits"

Would it really screw up the system if we re-plumbed it so when we wanted to clean it there was no recirculation ?
Quantity in = quantity out and in short order the system would be flushed.

We could do our spring flushing with 1/10th of the water and get much more effective in season "rinses" if we could do a straight through and down the drain flush, couldn't we ?

My understanding is the quantity of permeate going around and around (many passes over the membrane) is what rinses them.

The permeate normally goes straight down the drain. That's the clean stuff and I'm not worried about that. It's the concentrate side that gets the preservative, the bio-film, the alk and the acid that I want to flush more efficiently.
