You can find the solvate package in
~/lib/vmd/plugins/noarch/tcl/solvate1.2/ (or wherever you decided the
vmd libs have to be installed in your config file).
My guess is that they are using a pre-equilibrated w-box in wat.pdb.
Anyway, the fact that the box gets deformed during equilibration cannot
be related to the equilibration state of the water molecules. I would
say that the problem might be related to the PBC definitions. What unit
cell shape are you using? Cubic? What are your three vectors? Are you
doing NVT or NPT? What kind of deformation does the box undergo?
