The water tower does not open. The missing signal flag is on top of the tower and can only be reached by the jetpack.

No
The flag is on top of the Water Tower in Early Poptropica. You will need the jetpack to reach it. (see related question)
You don't fix the leak on the water tower. It is not part of the island quest.
That would be the lighthouse. You get it on top of the water tower, but you need a jet pack.
you have to go to the giant layer on top of one of the buildings then at the end you fall through the clouds on top of the water tower
Not and still be a tower. The Signal Flag is atop the water tower on Early Poptropica, but you can't jump up to it. You will have to go the long way. (see the related question)
You should be on Main Street. (Remember that if you're not sure where you are, you can check your Map!) Go all the way to the right until you come across a sign that says "Early Poptropica". Click on the sign to go there. Go right again and you should arrive at Early Poptropica. Then you cannot open the tower.
On the island Old Poptropica on the water tower.
It is to get you to look up there. Your final missing item, the signal flag, is on top of the tower. You cannot get it until you have obtained the Jetpack.
The flag is on top of the Water Tower in Early Poptropica. You will need the jetpack to reach it. To get the jetpack, you must go through the clouds in the sky, so you need the Golden Egg from below Poptropica Towers. To get the egg, you need the glow stick from the well in Early Poptropica village.
You need to get the jet pack from the aerial graveyard, and then use it to fly to the top of the water tower on main street. There will be the flag.
yes there is a flag in poptropica it is on the water tower but I don't know how to get up there if you talk to the guy standing by the water tower he will tell you it is up there
