If your toilet isn’t flushing all the way, it’s most likely because of one of these problems: The water level in your toilet tank is set too low. Problems with your flapper. A clog in the toilet, flange or drain.
Why is there no water coming into my toilet tank?
No Water in Toilet Tank
If there’s no water in the toilet tank, make sure the water supply valve is fully turned to the open position and check the water supply line for leaks. Make sure there’s no problem with the water supply to the bathroom or rest of the house.
