How to replace the float valve in a toilet tank
When a hygienic float valve goes bad, that means that the tank can no longer hold water between discharges. As a result, the toilet is running constantly, which wastes a large amount of water and can lead to utility bills. Replacing the float valve is a simple home repair that requires only a few instruments and about a half hour of maintenance staff time.

Instructions
1 Turn off the water supply to the toilet bowl by turning the valve handle located behind the toilet. Lift the lid of the toilet tank and keep it in reserve. Pull the chain so that all the water runs out of the tank. Use a sponge to absorb any excess water left in the tank.
2 Place a towel on the floor at the base of the back of the toilet. The towel will absorb water that leaks from the toilet during the process.
3 Use a pair of pliers to disconnect the pipe from the wall to the toilet tank. Disconnect the hose at the end of the tank by loosening the plastic nut that connects the hose to the tank.
4 Switch to a spanner. Use the wrench to loosen the nut that holds the float valve in place. The nut is located near the area that the hose is fed into the tank.
5 Release the thin plastic tube inside the valve tank and lift the valve from the toilet tank. Discard the old valve.
6 Read the instructions that accompany the new float valve. Install the rubber grommets firmly into the hole of the float valve on the base of the tank. Insert the new float valve into the hole and carefully tighten the retaining nut on the bottom of the tank.
7 Reconnect the hose to the valve and connect the thin plastic hose inside the toilet tank to the valve. Make sure all stamps are in place. Open the water supply and see if there are leaks around the tube. Tighten the seals and the plastic nut, if necessary.
8 Look inside the tank, as it fills with water. If the valve is installed correctly, there should be no leaks and the water line should be about a half inch from the top of the tank.
