How much is too much?
 

From what I have seen, most household pressure regulators are adjustable. (if you can find it ;) )

How much is too much?
 

Ok well I tested out my RO/DI, it has two 50 gps membrains on it so I should be able to push out 100 gpd.

the average I got was 86 GPD @80 PSI, 13.6 degrees C or 56.4 degrees F, TDS in was 29ppm and final was 0ppm. PH in was 7.1 and out of the DI it was 7.8
by looking at the tempature charts I am getting over the rated amount for that tempature so I guess that is good [img]smile.gif[/img] next thing to buy is a high quality PSI regulator so I don't have to adjust my tap to get the 80 psi.
