When this hollow container floats to a certain height, the valve stops letting water into the tank. When you flush the toilet, the float falls with the water level and reopens the water valve. To prevent water from refilling the tank, you’ll need to secure the float to prevent the valve from opening after a flush. Position the piece of wood vertically so that the bottom of it rests on the bottom of the tank. This way, the top of the wood will hold the float lever up and prevent it from causing the tank to refill after a flush.  For best results, use a piece of wood that is about 1 inch (2.5 cm) shorter than the height of the tank itself. If the sides of the tank are too high to do this, then straddle the board above the float lever and wrap a length of stiff wire around both the float arm and the board to hold the float up. The tank will empty, while the wood or wire strapping holds the lift arm up, preventing the valve from refilling the tank. If your toilet is clogged and you can’t flush it, you can also use a bucket or tall cup to lift the water out of the tank until it’s empty. After you’re finished with your repair work, simply remove the board and or strapping to allow the float to refill the tank. Place the lid back on the tank and you’re good to go!
