KZ Coyote 20C fresh water drain

I just got a new to me Coyote 20C; I found the grey water and black water pull out drains ok and finally found the small gate valve type fresh water drain under the dinette. I opened it up (I think) but couldn't see where the fresh water would drain. Does it drain back around where the grey and black water drains are or somewhere else?

Thanks.
Don
