    To pinpoint the leak, first dry the area around the supply line. Then, observe if any water drips or seeps from the connection points or along the line itself. This initial step helps confirm the source of the leak.

  2. Turn Off the Water Supply

    Before you begin any repairs, ensure the water supply to the toilet is turned off. Locate the shut-off valve behind the toilet and turn it clockwise until it stops. This prevents water from flowing into the toilet while you work.

  3. Disconnect the Old Supply Line

    Using an adjustable wrench, disconnect the supply line from both the shut-off valve and the toilet tank. Place a small bucket or towel underneath to catch any residual water that may spill out. Carefully unscrew the nut connecting the supply line to the fill valve.

  4. Inspect and Prepare the Connections

    Once the old supply line is removed, inspect the threads on both the shut-off valve and the fill valve for any signs of damage or debris. Clean the threads if necessary and wrap plumber’s tape around them to ensure a secure and leak-free connection.

  5. Install the New Supply Line

    Attach the new supply line to the shut-off valve first. Hand-tighten the nut, then use an adjustable wrench to secure it further. Be careful not to overtighten, as this can damage the fittings. Repeat the process to attach the other end of the supply line to the fill valve on the toilet tank.

  6. Turn On the Water Supply
