It is a common issue with toilets to randomly run for a few seconds every few hours. Water may randomly flow into the bowl too.
Worry not, there’s no ghost flushing your toilet. It is an error you cannot see!
The Flapper May Be Cracked
Inside the toilet is a tank with a flapper. When you flush, the tank empties water into the bowl.
With this, the tank fills up again, and the flapper closes shut to seal the tank.
However, with time, the flapper may become rigid and tighten up, or it may crack. When the tank fills up, the flapper is not able to fully seal it, and water drips down into the bowl.
When a sufficient amount of water leaves the tank, the tank refills again. This is the noise you hear of your toilet randomly running for a few seconds.
When you flush, a chain pulls on the flapper to allow it to open or close. This chain is crucial in the proper functioning of the toilet tank.
If the chain is too long, broken, or too short, or is linked to the wrong link, it can cause the tank to not seal properly.
Once again, water keeps running into the toilet bowl, causing the tank to refill soon. Once again, you hear your toilet randomly running.
The Float May Be Too High
If the tank has too much water and overflows, water runs into the overflow tube, and the toilet keeps running.
To avoid this, the float has to be lowered, so the water level stays low.
Faulty Refill Tube
Your toilet’s refill tube might be faulty too. In this case, water keeps flowing from the tube into the bowl, creating low pressure in the tube.
Therefore, water from the tank moves to the tube and causes the tank to need refills repeatedly.
Toilets may randomly run, but it is due to issues that can easily be fixed.
Rather than ignoring the issue, which might worsen the problem, fix it as soon as possible.
