Constantly flowing water flush: what’s the problem? Which solution ?


The flush of your toilets does not stop flowing, which makes it difficult for you to flush the toilet correctly, makes an incessant noise of water and generates significant water losses. Fortunately, every problem (or almost) has its solution and it is possible to fix your toilet flush without calling a plumber. Let’s do a check in.

Why is the toilet constantly flowing?

It is estimated that a constantly flowing toilet flush can waste almost 150 liters per day. Better to quickly find a solution to avoid seeing the amount of your bills soar.

You should know that toilet wear is normal. In fact, the toilets are permanently in contact with water and its oxidizing components. However, lime and other corrosive elements alter the various components of the flush and deteriorate it, which disrupts its proper functioning. Thus, when you notice a water leak at the level of the flush which causes it to flow permanently, it is recommended to act without delay and identify the origin of the problem in order to remedy it quickly and effectively.

To do this, turn off the water supply to the toilet in order to stop the filling of the flush and its flow. Then flush the toilet several times to completely empty the tank. Remove the lid from the latter and observe to determine the source of the leak.

What are the causes and solutions for a flowing toilet flush?

Here are the main causes of a flowing toilet and the solutions to be taken.

The float in question

The float is often the cause. With erosion and limescale, it bores, breaks or becomes blocked and no longer rises properly to the surface, causing continuous overflows.

The solution is simple. In this case, all you have to do is replace the float with a new model suitable for your sanitary model. To avoid mistakes, take your old disassembled float to a DIY store. If it is only calcified, take it apart and let it soak in a bath of lukewarm water and white vinegar before putting everything back together.

In some cases, the float simply goes out of order and can position itself too high or too low, until it starts to flow. It then suffices to put it back in place manually, possibly by turning the rod or screwing it back on.

The valve in question

The valve located at the bottom of the flush helps to seal the tank when it is closed. With erosion and limescale, the valve may not close properly and allow water to flow between the tank and the bowl.

In this case, it is sufficient to descale the valve if it is only calcified. To do this, immerse it for a few minutes to several hours in a bath of lukewarm water and white vinegar and let it act. If it is too worn out, it is better to replace it directly.

The joint in question

In addition to the valve, a seal ensures the seal between the bowl and the tank. If it is scaled, cracked, worn or displaced, leaks are possible. If it is the cause, it suffices to replace it with a new equivalent model, but to do this, it is necessary to disassemble a good part of the toilet, in particular by separating the bowl and the tank. The operation is not as complex as it seems, but it requires the right equipment and a little patience.

If despite everything your flush continues to leak, then it is best to call in the services of a plumber.
