If your toilet tank is leaking water, you are likely wasting unnecessary money on your water bill and it may also be a sign that something is damaged in your home's plumbing system. However, don't worry, in this article we will show you some simple steps to fix a leaking toilet tank.
You can do it yourself without the need for professional help!
Why is the cistern leaking water?
There are numerous possible answers to the question of why the tank is leaking water, although we should check the different potential sources of problems before fixing the leaking tank.
It is important to know where the source of the water leak is located.
First of all, we should check if the water is coming from the tank or from the toilet bowl. If the water is coming from the toilet bowl, you may have a problem with the bowl seal, as well as its connection to the drain pipe, where if there are sealing issues, it would be best to call an expert.
If water is overflowing from the tank, it is most likely that you have a problem with the fill valve (float) or the flush valve. Therefore, you should check why this device has stopped working, and if it cannot be repaired, purchase its replacement at GroupSumi.es
What to check if my cistern is leaking water
Filling valve
If your cistern is continuously leaking water, it is possible that the fill valve is defective. The fill valve is responsible for refilling the cistern after each flush. If the fill valve is not functioning properly, the cistern will not fill correctly and, as a result, will continue to leak water.
👉 To fix a faulty fill valve, follow these steps:
Turn off the water supply to the tank (there is usually a valve at the water inlet connection).
Remove the tank lid.
Observe the fill valve and check if there are any broken or worn parts.
If there are broken or worn parts, replace them with new ones. At GroupSumi, you can find all kinds of accessories for these types of repairs.
If the fill valve is very worn, you may need to replace it completely, ensuring proper functioning as well as greater longevity of the part.
Flush valve
If the cistern leaks water immediately after flushing, it is possible that the flush valve is defective. The flush valve is responsible for allowing water to flow from the cistern to the toilet bowl during the flush. If the flush valve is not functioning properly, water may continue to flow after the flush, and therefore, the cistern will keep leaking water.
👉 To fix a faulty flush valve, follow these steps:
Turn off the water supply to the tank (there is usually a valve at the water inlet connection).
Remove the tank lid.
Observe the fill valve and check if there are any broken or worn parts.
If there are broken or worn parts, replace them with new ones. At GroupSumi, you can find all kinds of accessories for these types of repairs.
If the flush valve is very worn, you may need to replace it completely, ensuring proper functioning as well as greater longevity of the part.
Float
Another common problem that can cause a tank to leak water is a defective float. The float is the part that controls the water level in the tank and can be responsible for a tank that continuously leaks water.
👉 To fix a faulty float, follow these steps:
Turn off the water supply to the tank.
Remove the tank lid.
Observe the float and check if it is damaged or if there is any obstruction in its movement.
If the float is damaged, replace it with a new one.
If there is any obstruction, remove it and ensure that the float moves freely.
Rubber Seal
The rubber gasket is another part that can cause a cistern to leak water. The rubber gasket is located between the tank and the toilet bowl and is responsible for sealing the connection between the two.
👉 To fix a defective rubber gasket, follow these steps:
Turn off the water supply to the tank.
Remove the tank lid.
Check the rubber gasket and verify if it is worn or damaged.
If the rubber gasket is worn or damaged, replace it with a new one.
Make sure the new rubber gasket is properly installed and sealing correctly.
Additional tips for fixing a toilet that is leaking water
In addition to the steps mentioned above, here are some additional tips that can help you fix a toilet tank that is leaking water:
Clean the cistern regularly to prevent the buildup of sediments and minerals that may affect the functioning of the valves.
Check that the water level in the cistern is correct. If the water level is too high, it may be overflowing through the overflow tube.
Regularly check the condition of the cistern parts for any signs of wear or damage and replace the parts as needed.
