The water level in the toilet bowl can be fixed by a few quick adjustments. The majority of the time the ball float in the tank is the culprit for low water level in the toilet bowl. Here's how you can fix this.
Step 1 - Lift the Lid
Remove the rectangular lid from the top of the tank on the toilet bowl.
Step 2 - Ball Float
Locate the ball float. It is not difficult to find, as most traditional toilets have this installation. It is a plastic ball that is connected to a rod. The rod is connected with a straight plastic structure. You will find a screw where the rod and the plastic structure connect.
Step 3 - Adjust
You can control the movement of the plastic ball by turning this screw. Turn the screw towards the left and the ball float will lift on its own. The water will now start flowing into the toilet bowl. When the water stops flowing, it is an indication that the ball has hit its original position.
The problem has been solved. Now replace the tank lid and check the water level in the toilet bowl.
