hi all,
i have an RO unit from osmotics, and have set it up as portable (3 ball valves, one on each of the lines so i can block of a line and drain it etc.
my question is that i thought you always had to have the (black) waste water line open, which meant that i was getting 10-15 litres of waste for every 1 of RO. I understand that if you turn the existing valve that comes with the system it does not filter anything and diverts it all down the waste pipe.
however if i block of one of my new ball valves which is on the outlet side on the unit, i get 0 waste water and still the same out of RO. (obviously a bit more back pressure but not alot)
should i leave the waste water line open and accept that i will have loads of waste, or should it be shut off, so all that comes out the system is RO
cheers
