we have the dump valve also but have found it to be unnecessary (since we use the levelers & only have bags on the rear).
ours has a mechanical linkage (rod) tied from the pumpkin to a frame mounted dump valve....when i deploy the levelers the linkage activates the dump valve. I haven't looked at it but i suspect i could reset the height of the mechanical link/rod to gain some added height....but the rods job is there to "set the height" of the coach/box.
