To the best of my knowledge and knowledge, you are driving in the opposite direction, that is, the upper tank should fill the lower one with a closing float, the filling will be popr the upper one, and the exit to the house will be through the lower one, with that you will never have problems, because the water must circulate systematically, and exchange continuously, without running the risk of having stagnant water in the lower one. luck
Thank you very much. Will it be necessary to put a jug on the bottom or just with the jug on the top will it be enough?
I don't know what you call jug. It will be float type switch for level control .. ???
If the tank is closed, you need to break vacuum when unloading, but you also need to dump the air when filling.
In short, it MUST NOT BE CLOSED.
I made a mistake by pressing the button of the best solution. THE BEST IS THIS. Thanks again,
