Editor's Pick: If your toilet tank keeps making noise or fills slowly, it's most likely the fill valve has worn out. This model adjusts from 9 to 14 inches (23 to 36 cm) in height, so it fits most tanks. It fills quietly, so flushing at night won't wake the family. The large adjustment knob turns easily, and you can set the water level yourself. The anti-siphon design is also certified, so once it's installed, you basically don't have to worry about it again.
