    In theory, exactly right. But the ISS recovers water from both cabin air (for 
    more drinking/washing) and from urine (for electrolysis into oxygen), and 
    there's some excess of the latter. PLUS the humidity recovered in the US 
    segment cannot be transferred to the Russian segment's equipment for 
    re-purification, there are some equipment problems, and there's also problems 
    with the dump valve. So they throw away water now as a fairly temporary 
    expedient.
