The Ibergrif M20522 is designed for homeowners and DIYers seeking a durable, water-efficient replacement for standard toilet tanks. Its primary benefit is a high-sensitivity dual-flush mechanism that allows for precision water usage, though it is important to note that this model is strictly for 2-inch drain outlets and will not fit smaller 1.5-inch systems.

No, this valve is strictly designed for 2-inch (59-61mm) tank openings.
The wire control offers smoother, more sensitive flush activation and allows for more flexible placement of the flush button compared to rigid rods.
Yes, the M20522 kit includes the dual-flush button assembly.
Ensure the surface around the drain hole inside the tank is clean and smooth before tightening the unit with the included silicone gasket.
The unit is made of high-quality ABS plastic resistant to corrosion and acid, though harsh chemical cleaners should generally be avoided inside toilet tanks.
Check if the silicone gasket is seated correctly or if there is debris preventing a tight seal at the base of the tank.
Verify that the control wire has no sharp kinks or bends and that the cable housing is securely attached to both the valve and the button assembly.
Ensure the base mounting nut is tightened sufficiently and that the silicone gasket is centered around the flush hole.
Installation requires removing the existing flush valve and verifying the drain hole diameter is between 59mm and 61mm. If the tank is a 1.5-inch model (48-50mm), this unit will not seat correctly and cannot be used. When installing, tighten the base nut firmly but avoid over-torquing the plastic components to prevent cracking. For care, avoid using harsh chemical cleaners directly inside the tank, as these can degrade the ABS plastic or the silicone seal over several years. Periodic inspection of the flush button wire is recommended to ensure no kinks have developed.
