FAQ

Measure the diameter of the hole in your toilet tank lid. This button is designed for a 48mm (1.89 inch) mounting hole. It is compatible with most standard dual-flush toilets that utilize a top-mounted push-button mechanism.
You likely need a replacement if the button sticks, fails to return to the upright position after being pressed, or if the internal plastic clips that secure the button to the tank lid have snapped due to wear.
Installation is straightforward and typically takes less than 5 minutes. You will need to unscrew the plastic retaining nut from the underside of the tank lid to remove the old unit. Once the new button is inserted, hand-tighten the nut until secure. Do not overtighten, as the plastic threads can be fragile.
Yes, this unit comes with adjustable rods. You may need to unscrew or trim these rods to the correct length to ensure they make proper contact with your specific flush valve mechanism inside the tank.
The primary cause of failure is mineral buildup from hard water, which can cause the internal springs or sliding components to seize. Additionally, the plastic tabs that hold the button in place can become brittle and break after years of repeated mechanical stress.
