I just purchased an
RO/DI unit from the filter guys. They are local so i didn't have to pay to ship

. I have a T and will be branching off of my cold water supply line to my washer. Then running the one line to the washer and one to the
RO/DI unit. My question is that I would like to mount the unit in my fish room which is approximately 20' or less away on the next floor up. Can i run a single line from the supply line coming off off the cold water and run a line 20' up to my
RO/DI unit? Or would i need an inline pump to keep the pressure up?
thanks,
Kassun
