I have a 29.4 and my fresh water tank is behind the bedroom drawer cabinet and the fresh water drain for it is near the bottom of the tank. The only way to access it is to remove the second dresser drawer and literally climb halfway inside to turn the vale 1/4 turn. When it's empty you put it all back together again.
IF this is where your's is, PM me - I just made a quick fix for mine that no longer requires removing the dresser drawer. Much more convenient and only involved a little cutting..........
