I'm new to window cleaning, and have just set up my new vyair ro system (VYR-RO1/RO2N). The filtered water is coming out very slowly, it's trickling out and taken about 2 hours to fill up half of my first barrel. Is this normal? Does it take a long time? I seem to have more water coming out the drainage pipe. I have also installed the pressure tank that goes with this, but I don't have a clue what I need that for?? If anyone could shed any light on any of this I'd be grateful.
