Well most tanks are 4.4 gallons and if they are properly charged (which you can check and adjust) they should empty completely if allowed to. But that's not that relative because a tank doesn't change the run time on the RO. Without a tank the RO runs until you fill your glass, sump or whatever is full but it takes a while to do so. With a tank you fill your "whatever" quickly, draining the tank, while the RO runs until the tank is full again. So the duty cycle on the RO is identical.
