However, the exact details of how this occurs are often unknown to the average individual.

Water flows through the water line and up into the toilet tank using the fill valve tube.

As the tank fills with water, the float rod or float cup is forced to rise.

When the float reaches a set level, the fill valve stops water flow into the tank.

Some toilets also have a secondary entry point called a siphon jet that increases flushing power.

The overflow tube might be too short if the current flush valve assembly isn’t compatible with the toilet.

The tube could also have been cut too short during installation.

Make quarter-turn adjustments until the float is set to the desired water level.

Correct this issue by replacing the float.

Inspect the flapper for signs of significant wear, warping, or grime.

If the flapper is damaged, replace it with a new flapper.

A running toilet is typically sparked by the overflow tube, flush valve, or fill valve.

Check the water in the tank to determine if it is running into the overflow tube.

Fixing a running toilet is typically inexpensive, sometimes costing under $50.
