It's a watering can that is continuously fed through a rubber
the water that fills continuously but that, if we stop to rest for a bit until you upload is full and no overflows.
Step 1: The heart of the system
The second image shows how will their tubes, but, of course, still lacks something.
Step 2: Modifies it
To run the float to the inside of the watering can I had to reduce the length of the command bar of the valve. I then performed the holes to reconnect the two bar and to allow an eventual final adjustment of the system.
Using a self-locking screw I allowed a fine tuning of the location of the float.
Step 3: And mounting
For a proper keeping of hole I put two seals including one in the internal and external to the one that is also visible in Figure successive.
