A constantly leaking toilet tank can easily drive anyone insane. There are so many possible reasons for the tank to be running, and luckily, most of them are easily fixable without having to involve a professional plumber.
In this helpful guide, the Fantastic Services team will explain how to fix a leaking toilet tank by yourself, as a true professional would. This article is for anyone who wishes to stop that leaking toilet sound once and for all.
The system of the tank is a simple one, however, there are a few parts that could cause the water to run due to damage. Here are the most common reasons:
A flapper is the rubber part of the system within the toilet tank that lifts up to release water into the toilet bowl once you flush. After that, it goes back down to seal the opening and let the tank fill with water again. The most common reason for a leaking toilet problem is when the flapper cannot properly seal the opening.
Often, this is because of the chain that holds the flapper gets caught on something and makes it impossible for the rubber seal to do its job. To fix this, a simple readjustment by hand will be enough. The other option that the flapper might be damaged due to deterioration over time. If this is the case, you will need to replace the flapper with a new one.
The overflow pipe is a small plastic tube standing upright in the middle of the toilet tank. Its purpose is to drain the excess water when the tank fills up so it doesn’t end up spilling water. If you see that the fill tube is underwater, or if it’s broken, this might be the cause of your leaking toilet. You might have to replace the overflow pipe with a new one if you notice damages. If not, you just have to readjust the water level inside the tank.
The toilet float is another part of the system that regulates the water level inside the toilet tank. It comes in two variations – as a cup float and as a rubber ball float. If your toilet bowl is a new model, you probably have a cup float. If the water level is so high that it rises above the level of the overflow pipe, you’ll have to readjust it through the float.
If your toilet leaks only after use, then check our post on toilet leaks when flushed.
As you see, the mechanism inside your toilet isn’t a very complicated one, and with a little patience and understanding, you’ll be able to fix any small problem yourself. Of course, first, you’ll have to be certain you know the nature of the issue.

Once you’ve diagnosed your problem, it’s time to fix it. Replacing a toilet flapper is easy, you just need to follow these steps.
If the problem isn’t the flapper, but the water level being above the overflow pipe, you will have to adjust it. The water enters the toilet tank through a fill valve. The float on the valve adjusts the water level and tells it to shut off when the tank is full. Therefore, you can lower the water level in the tank by adjusting the float.
A ball float has a long arm attached to the fill valve. At the end of it is a rubber ball-shaped float. To adjust the water level, you have to turn the screw attached to the fill valve. Use a screwdriver and turn counterclockwise to lower the float.
A cup float has a small circular cylinder wrapped around the fill valve. The cylinder can slide up and down and its position determines the water level. Just lower the cylinder and the water level will be adjusted.
Finally, if the problem is not the water level, but the damaged overflow pipe, you would have to replace it.
