Leaky toilet flush: 6 tips to fix it depending on the cause

A leaking toilet flush may seem trivial. You tell yourself that there is no urgent need to repair it, even if on a daily basis, it is quite annoying to hear the water running day and night. However, beware of unpleasant surprises on your water bill. Find out now how to fix your toilet flush depending on the cause of the leak.

Here are some solutions to fix a leaking toilet flush

Toilet cistern still running after flushing usually comes from one of the mechanisms of the toilet: the float, the seals, or the toilet tank. We explain everything you need to check in order to determine the cause of your problem and repair your leaking toilets

1. Check the correct adjustment of the float

In the event of an incorrect setting, water can rise in the flush tank until it overflows into the overflow and drains into the bowl continuously. This malfunction will cause you to consume a lot of water for nothing, in addition to causing a constant filling noise, not to mention the sound of water flowing into the bowl. You just have to adjust the float so that it is a little lower in the toilet tank, either by twisting the metal rod that holds it, or by loosening the ring to which it is connected (it depends on your model) .

2. Check if the float is not scaled

Often the cause of a lot of trouble, the float must be adjusted and maintained correctly, otherwise, it could interfere with the proper functioning of the flush.

If it is seized up from lime and does not rise or fall properly, your toilet may start to make noise when filling very slowly or water may leak into the tub. A little white vinegar bath can solve the problem, but if the machine is damaged, it is better to replace it.

3. Make sure the water inlet seal is tight.

It may happen that the float has nothing to do with the leak in the tank and yet water is flowing into your bowl or under the tank. It will then be necessary to turn to the joints of the toilet.

First, the water inlet seal may be leaking, which can cause a flow to the outside of your toilet or along with the flush tank. A seal that is too old will be less flexible, damaged by limestone, and may even break down. Do not hesitate to replace it if it seems too old to you.

4. Check if the toilet tank gasket is properly fixed.

The second seal to check is that of the toilet tank, ensuring the junction with the bowl, also called a valve. It only needs to be misaligned for water to flow under the tank or into the bowl.

5. Visually check the good condition of the valve

If the valve is cracked or punctured, it will no longer perform its sealing function and cause a leak. It will also need to be replaced in this case.

6. Make sure the tank is not damaged or cracked.

Finally, it may be a problem with the tank itself and no longer with the flush.

Wear due to time, micro-cracks caused by the temperature difference between the cold water inside the tank and the much warmer ambient air or fracture due to shock, there can be many reasons that your toilet tank is damaged and starts to leak.

If the tank is damaged, a cursory repair may do the trick for a while, but the solution is often to completely change the cistern to prevent the leak from resuming or getting worse.

In any case, whatever the cause of the leak, do not delay in repairing it to avoid unnecessary overconsumption of water and avoid daily discomfort. If you don’t have time to take care of it or if you have two left hands, don’t hesitate to contact us.
