The filling valve, as the name implies, refills the toilet tank with water after a wash. These accessories are controlled by a set of valve float. As the water level in the tank rises, it leads up to the float valve, which finally cuts off the water supply to the fill valve when it reaches a predetermined level. The best way to repair a fill valve in a toilet tank is by replacing the entire filling valve assembly. They are not expensive and the work is not complicated, even for a plumber for the first time.

Instructions
1 Close the water for the toilet cistern. Follow the water supply valve from the bottom of the toilet bowl to its confluence with the supply valve on the wall. Turn the knob oval on the front of the valve to the right to close the water.
2 Remove the tank lid and set aside. Download the bathroom. Hold the handle down after pulling the chain and allow all the water inside to flow out. Wipe away any excess with the towel and sponge.
3 To remove the valve float from the filling valve. In most cases, the valve float can be separated by removing the two wing nuts that hold it. This step is not necessary in a filling valve with an integrated float.
4 Place a towel on the floor under the tank. Unscrew the water supply hose from the inlet on the bottom of the tank with a pair of pliers. Loosen the plastic retaining nut on the inlet. Lift the old fill valve up and out of the tank.
5 Clean the area immediately around the filling valve base at the base of the tank. Use a spatula to scrape and remove any buildup of sediment or calcium. Apply a light coat of silicone grease on the perimeter of the socket.
6 Insert the new filler valve into the filler valve socket. Make sure the gasket is tight on the bottom. Keep this with one hand. With the other hand, take the retaining nut and place it under the toilet cistern. Screw the retaining nut onto the threads on the bottom of the filling valve. Tighten with the key.
7 Replace the float assembly, if present.
8 Wrap the inlet threads of the fill valve in the bottom of the tank with plumber's tape. Fix the water supply hose and tighten with the pliers. Reset the water supply by turning the water supply button counterclockwise. Allow the bathroom to fill up
9 Pull the chain and check that the new filling valve is working correctly.
