If a leakage noise comes from inside the toilet cistern, the most likely cause is a worn fin. When the handle is activated, the fin is raised, which covers a hole in the bottom of the tank, and allows the water to flow out of the tank and into the container. When the handle is released, the hinge covers the hole and allows the tank to be refilled. If the trap is used, the water will seep into the container and make a noise leak.

Instructions
1 Locate the shut-off valve below the toilet tank and turn it all the way to the right to shut off the water supply to the tank. Remove the lid of the tank to gain access to the interior of the tank.
2 Pull the chain to remove water from the tank. Because the water supply is off, the tank does not fill.
3 Pull the stirrup fin. The fin is attached to the support by means of two plastic pins. Do not pull the pins too far apart or break the bracket.
4 Remove the chain from the top of the trap. The chain can be attached to the hinge with a clip. Alternatively, the end of the chain can slide into a slot in the trap. It is possible to extract the chain by hand or with a pair of pliers.
5 Place the new flap on the end of the chain in the same way as the previous one is attached.
6 Slide the new fin into the pins of the bracket.
7 Open the water supply and let the tank fill with water. Pull the chain two or three times to test the new fin. Replace the tank lid.
