Where are the valves to empty fresh water tank on Caravael 22FB?

[Bluetick]

The manual is pretty vague. I want to empty the fresh water tank but can't find the drain valve.

It varies by trailer model. Find the fresh water tank, and look underneath the Airstream in that general area. My valve is on the drivers/street side of the trailer, near the fresh water fill cap. In the case of my 23FB, there’s a white petcock valve that drains the fresh water tank, and two low point drain valves with red handles. Opening the white valve with the handle pointing towards the rear of the trailer will drain the fresh water tank.
