Unfortunately, I do not know the appropriate terminology but, there is a small hose that fits into a tube within a cylindrical container in the toilet tank. When this occurs, I can see initially hear and, after removing the toilet tank cover see water running from the hose intermittently; this also seems to have an effect on the water level in the toilet bowl.
I can temporarily solve the issue by removing the tank cover and inserting the small hose back into the tube. This works well for a while but, then the problem seems to reoccur. I live in a rental which most recently replaced our old-fashioned toilets with smaller “energy efficient” toilets. I cannot help but notice how flimsy the plastic parts are in the toilet tank.
Is there something that I could do to permanently stop the hose from popping out of the tube or is it necessary to call maintenance?
