Don’t be afraid when water fills the tank whenever you are trying to adjust the flush toilet. It is normal. The water shuts off when the water gets to the fixed level, when you are lowering the water level, and you are not going to see any changes until the toilet is flushed.

Step 4: Flush the toilet

Press down one of the buttons on top of the flush valve in the middle of the bathroom. Water gently exits the tank then refills.

Observe the new level, and if you have not gotten to the desired level, then you can adjust it. You can repeat this action as much as you like until you have gotten to your preferred level.

Step 5: Finishing

Do not forget the lid now that you are done adjusting the water level. Replace the lid. Just as you screwed in the dual flush, screw back the double flush line and peg the buttons back into its place, if it was removed. Do not also forget to adjust other dual flush toilets.
