Also in this case the process can be repeated and, after a certain number of suctions and compressions we reach a situation in which the tank and the part above the ascending pipe are completely full and the same amount of water that is sucked up passes into the highest glass of the exhaust pipe, through which it returns to the basin.
In the end, the ovoid tank, the part above the ascending pipe and the pipe connecting them to the base of the pump body remain full. To empty the ascending pipe, a small pipe with a cap at the base of the ovoid tank, above the valve, is used; to empty the connecting pipe, the one used to empty the pump body is used.
The possibility of making the water follow the second path, in which it is raised to a greater height than in the former, highlights the fact that the limit on height that can be reached depends only on the force acting on the piston.
