@bluespirit - If you look closely at the components in the flush tank try to find a little tube (and is often black). One end of this tube is likely supposed to be where the water is spurting out.
This tube can sometimes come off because of the wet area it is in. But it should be an easy fix with no need to call the plumber for it.
Also another fun tip while you are hanging out in the flush tank, if you fill up a 2 liter bottle with sand or rocks and put it in the flush tank you can save on your water bill because it will need less water to fill your toilet.
Good luck with the spurtage!
