Turn Off the Water Supply: Locate the shut-off valve typically found behind the toilet and turn it clockwise to stop the water flow. This step is essential to avoid any water damage or complications while you work on the cistern.

Remove the Cistern Lid: Gently lift and set aside the lid to prevent breakage. This will give you access to the cistern where the block will be placed, allowing you to work efficiently.
