FAQ

Measure the diameter of the hole in your toilet tank lid. This button is designed for a hole diameter of 38mm (approximately 1.5 inches). If your existing hole is significantly smaller or larger, this unit will not fit securely.
Installation is straightforward and typically requires no specialized tools. You will need to unscrew the plastic nut from the underside of the button assembly to remove the old unit. Once the new button is inserted into the lid, hand-tighten the nut until secure. Avoid using pliers, as overtightening can crack the ceramic lid.
Yes, the threaded rods on the back of the button can be cut to length to match the specific depth of your toilet tank. We recommend measuring the distance from the lid to the flush valve mechanism and trimming the rods accordingly to ensure a clean, responsive flush.
You should consider replacing the button if you notice the flush mechanism feels 'mushy' or unresponsive, if the button sticks in the down position, or if the plastic threads have become stripped, preventing the button from staying firmly attached to the tank lid.
These buttons are subject to constant mechanical stress and exposure to mineral deposits from hard water. Over time, the internal springs can lose tension, and the plastic components can become brittle or calcified, leading to sticking or complete failure of the dual-flush functionality.
