How best to transfer 2 liters of liquid from one container to another and back again? Answered
I'm bulding a cleaning machine.
I need to transfer 2 liters (.53 Gal) of liquid (water with a small amount of cleaning agent) from one container through a filter to another empty container of the same size, quickly.
I would like to accomplish this buy pressing a button.
Then transfer the liquid back to the original container.
Looking suggestions on how best to accomplish this.
