Why Is My Toilet Always Running

On a conventional toilet, once you turn the flush handle, this lifts the chain on the flapper releasing the water in the tank and allowing the toilet to flush. The flapper then closes and water starts to fill the tank. The water filling the tank raises the float on the fill valve to it’s set level. Once the float reaches the set level it stops and the water filling the tank stops filling.

Problems With The Toilet Flapper

Over time, the flapper can begin to deteriorate or accumulate buildup on the under side which affects it’s ability to seal properly. If the flapper is not sealing, water can seep out of the tank which in turn lowers the level of the water in the toilet tank. When the water level inside the tank drops even a slight amount, this triggers the fill valve to begin to fill the tank with water to replace the quantity of water lost by the defective flapper. The fill valve will continue until the float rises back to it’s set level. This is one way in which the toilet will run.

Toilet Fill Valve Problems

Sometimes the problem of a cycling toilet can be found in the fill or flush valve. When the valve is installed properly with the float set at the proper level, the toilet should work fine. But over time, fill valves can go bad and will need to be replaced themselves.

Toilet Overflow Valve Problems

At the top of the flapper assembly is a tall tube called the overflow valve. This tube is usually higher than the water level in the toilet tank when the float on the fill valve is set correctly. However, if the float is set too high and the water level is too high,  just enough to trickle over the top of the overflow valve, your toilet will be in a constant state of fill as the fill valve will always be filling and the excess water will be flowing over into the overflow valve. Another type of water running in the toilet.

A visual inspection of the inside of the tank will give you an idea of where the problem is occurring. Of course, it’s always best to have an experienced plumber to examine the toilet to determine the reason for the randomly or constantly running toilet and be able to repair the toilet on the spot.
