Trophy 2159 water tank drain?

[Degree of Freedom]

Recently bought an old 2159...can't seem to find a way to drain the water tank...surely I don't have to empty it through the tap?[?]

Options are:

1. The tap.
2. Syphon via the filler (won't get all the water however).
3. Disconnect plumbing at the tank.
