Water consumed even earlier than 24hours (say, 1 week water "flushing") will do, um, jack shit.
Not true really... if what you are trying to do is dilute your piss, then drinking as much water as you can right up to your test, will fill your bladder up, and dilute the piss. This may not pass and they may ask you to take another one, but at least you did not fail for a drug.
