Little to no chance the tank is pressurized:

didn't say the tank is pressurized. i said 'from the house' it looks
like it is pressurized, implying that it's not a gravity pressurized system.

Presently, there is a chlorox bottle floating in the steel tank which is
roped to a red wooden block that moves up when the water level goes down
(and vice versa).

After reading several more posts is seems to be that this is a gravity
tank presumably on a hill, with a booster pump near the house.

already stated the pump is next to the tank
