Water tower removal soak option

["O'Farrell, Fergus" <Fergus.OFarrell@ngc.com>]

Just an idea, or silly option.
When trying to get the water tower loose, and failing, I'd try making
some sort of seal that you dropped in over the thermostat and filing the
area with a water/vinegar mix.  It is quite good at water scale/minerals
and such, all ya gotta do is figure out a way to keep it in place
soaking the joint.
