    The connection between 2 and 3 is blocked.

    Even if you assume that it is not blocked, it is still 5. The pipe from 2 to 3 is never reached because 4 leaks out the hole in the bottom. Assume that the hole in the bottom is a flaw and 4 still leaks out the top before the pipe to 3 is reached.

    1 can also fill up if the flow from the faucet is higher than what can exit through the pipe connecting to 2.
