These are 3 of the fountains used in my world that I created. One of them can be turned on / off with a redstone system.

The operational fountain has 2 ways it can be activated. The first uses a mock piston pump that runs on a fast cycle. This can be laggy, however the piston will stop once the game or server is restarted removing any lag and the fountain will remain flowing. The second method uses a lever which bypasses the piston pump, both ways are shown in my video.

Feel free to use or modify these fountains for any personal use, just do not redistribute them.

If I create more fountains in the future I will add them to this page.
