New to RODI

I've been messin' around with the flush valve on the RO unit. I've found that I can totally shut off the waste water line, and then I get nearly 100gpd, based on some math.
I think I'll run it around 80gpd and flush it every couple of hours.
Otherwise, if I use the valve in it's normal position, I only get about 40gpd, with a lot of waste. No point wasting all that water with the incoming TDS @ only 7-8ppm.
