The bowl unit and the upper tank are the 2 core parts of home toilets. The bowl unit is positioned on the floor. And the top tank holds water that releases water every time you flush the toilet after using it.

You will not find any moving parts in the bowling unit, and it is a solid piece of porcelain. Moreover, it doesn’t show any problem except for a few exceptions.

While the tank portion contains a few important components, which are the fill valve, handle to initiate the flush, etc. And most of the time, the toilet fill valve leaking from the top happens in the tank along with other problems.

So, are there any methods to fix these problems? Let’s explore to learn the fixation processes of different toilet valve leaking problems.

How to Fix Different Toilet Fill Valve Problems?

Toilet Fill Valve

Ballcock Replacing

Different designs of toilet refill valves are available. “Ballcock” is the older style; it is an empty floating ball that controls the water flow and operates the valve.

However, fill valves are known as ballcock, but the term only applies to 2 types – plunger and diaphragm. Float balls are available in both types responsible for operating the fill valve using a long arm involved in the ball.

You will hardly find ballcocks in modern toilets. Older toilets can go with both plunger and diaphragm type fill valves. The working process is so simple. When the water level requires adjustment, the float bends up and down to find the shut-off point of the water supply. And once the float gets to the point, it stops the water supply to flush.

When you experience runny toilets after the flush cycle is finished, it happens mostly due to the tank’s high water level. At this point, the floating arm will bend downwards to stop supplying water at a lower level.

Ballcock valves show problems from time to time, and if you face issues with this valve type, it would be best to replace the valve with a more modern float-cup style fill valve. Valve replacing is not a challenging task at all.
