2. Remove the Toilet Seat and Lid
Lift the toilet seat and lid off the toilet bowl. Set them aside in a safe place.
3. Disconnect the Water Supply Line
Use an adjustable wrench to loosen the nut connecting the water supply line to the fill valve. Carefully disconnect the line and place a sponge or bucket underneath to catch any water.
4. Remove the Old Dual Flush Valve
Use a screwdriver to remove the screws holding the old dual flush valve in place. Lift the valve straight up to detach it from the toilet tank.
5. Install the New Dual Flush Valve
Place the new dual flush valve into the tank. Align the holes and insert the screws. Tighten the screws using a screwdriver.
6. Reconnect the Water Supply Line
