How the assistant tank works
A. It's used to add water into the big solar water tank
B. From the 1st picture, you can see that there is a floating ball and plug inside the asistant tank.
C. When the water level inside the big solat tank descends, the floating ball in the asistant tank will go down, the plug in the asistant tank will open, the cold tap water will go into the asistant tank, go through the plug and then into the big tank. After the big tank filled with enough water, the floating ball will rise, then the plug will close. When the water level in the big tank descend again, the asistant will do the same repeated work again and again.
