How to Adjust the Dual Flush Mechanism? – 5 Steps to Follow

Dual Flush Mechanism

Step 1: Remove the dual flush toilet lid

In most dual flush toilets, the first thing to do is to unscrew the push on top of the cover; then, you can lift off the lid. When extracting go anticlockwise. If you cannot remove it that way, or you notice that the button isn’t unscrewing, push down one of the pins as you remove the other pin from the bottom. Now you can do the same thing for the other button after removing the button. Then you can unscrew the flush button assembly.

Step 2: Adjust the level

Adjusting the level of the water of the dual flush is simple. These toilets use a combined assembly float, which pushes up and down as dictated with water level controlling the flow of the water. The ring-shaped contraption which fits over the valve by the left-hand side of the toilet is the float.

Based on the type of valve, there are two ways by which to adjust the water level. One of the route is through the screw sitting on top of the fill valve assembly.

Step 3: Tightened the screw

When the screw is tightened clockwise, the water level is lowered. However, when it is tightened anticlockwise, the float moves up, which raises the float higher, and this raises the water level. The other way as to do with pressing both sides of the lock, which fixes the float valve on the fill valve line rail that is attached to the side.

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.

To conclude, the dual flush toilet is a handy system bound to save you money as well as giving you the satisfaction of contributing your own quota helping to conserve water.
