I have setup my compact ro filter & I am struggling to get any output water. I don't know what the pressure is but I have since bought a booster pump & that hasn't really made any difference. It's probably been running about 3 hours in total on & off and there is only about 2 pints of output water. I've tried reinstalling the membrane & nothing seems to work. I've had an ro filter before, years ago & didn't have any problems. Any help would be appreciated, thanks.
