Was it an instant dipstick test or a lab test? If it is a lab test and someone drinks THAT much water, they are going to be in danger of getting a negative dilute test and depending on who requests the test, you may or may not get to retest. The goal of dilution is to dilute enough but not to produce straight water instead of urine. There is a formula that should be followed to ensure a negative result without failing validity testing to see if you diluted.

Personally, I like to post first hand info and not info from "gossip", it tends to be more accurate.
