What Is A Cistern? 

A cistern is basically used for the flushing process. It is a tank for storing water. The water stores in the cisterns of the toilet.

It’s better to thoroughly check the pipe and check in the clamp using a screwdriver. Do not tighten the fittings very hard as it might cause the water inlet valve to close while closing the clamps. This will stop the toilet from refilling again.

Further, try to actively move the fixtures by using a screwdriver to make sure they are tightened perfectly. If the problem is still not solved, another option could be the blockage of sound in the tank.

Another issue can be found in the persistence of water flow. This might be the reason for a noisy flush because of the speed water is refilled. Check and tweak the water valve to adjust the speed. The valve can be found outside the tank or behind the toilet.

Letting a lot of water at a fast speed into the cistern can be noisy. When the water valve is adjusted to a maximum speed, flush the toilet again to see whether it makes any improper sound or not. However, after this adjustment, the water flow might slow down, and the cistern will take longer to fill up again.

Then you should put a brick inside the cistern that will help in displacing water to the top. It will give the ease to will cistern with a smaller amount of water.

The less the water flows into the toilet bowl; the less the flush noise will be. Also, this method helps in saving water as well as reducing water noise.

Check The Water Tank

If the problem is still not solved, the problem might be in the tank. Therefore, it is compulsory to check out the tank beforehand.

Sometimes sounds can be produced from the end of the water flowing process. It can also be linked with the further larger process of water tanks. So, blockage of the water to completely fill in the tank can be beneficial, and it may suppress the sound.

You can try changing the position of the valves in the toilet tank or try altering the tank float slightly. It may help in the reduction of noise.

Block The Sound

Moreover, the next step is to remove the tank’s lid and clean the edges of the tank. Then dry the tank and cut adhesive foam to place it around both of the edges. Also, lightly press and close down the lid to block out the sound created by the toilet. The airborne sound will be unable to travel out and will cease the sound.

It is better to soundproof the toilet cistern. This trick is normally used for doors, and adhesive foam tape is used for sealing. This method can mute the sound and can make them sound to slow down rather than rise up its high noise.

For more soundproofing, you could also use the cistern cover on the toilet, which will help in dampening the sound.
