hello: if it is the inlay tank of the toilet the plastic buoy is better because the telgopor brakes them to the rosar walls of the cement tank, another thing is to know what water pressure you have if there is a lot of pressure because it is a apartment in a building or you have a pressurizing pump, the water pressure may be overcoming the immense valve mechanism if that is another type of valve that are placed in those cases is that of the image to solve it place this type of valve leaves the shutter pipe at least 3 cm or 4 cm below the edge of the tank so that the water is fenced to the toilet by the pipe of the shutter without overflowing and falling to the floor any doubt comments greetings
