Usually when you flush, the toilet will automatically refill the water in the tank and automatically stop when the blue plastic ball rises to the top. However, now the blue plastic ball won't rise to the top properly and so it keeps on refilling the water. It doesn't overflow, but it's very noisy and wastes water. For now, I'm using a piece of tape to hold up the ball up once the tank has refilled, but I have to undo the tape each time i flush so the tank can refill the water.
Please help - does anyone have any advise??? Thank you!!
