What is the max back pressure on a RO unit

[jgoldsney]

Well as I consider my new tank install, I have decided that the space in my stand even with the re-designed sump is too small for my RO/DI unit.

I am considdering putting my RO unit in the basment and running a line up to the tank. The length of 1/4" line would be at least 60 -70 ft.

Does anyone know if this will be too much back pressure on the RO Unit.
