How to change a toilet cistern

If you have a leaky or broken toilet cistern, it may be time to replace it. While this task may sound daunting, with the right tools and guidance, you can easily change your toilet cistern by yourself. This step-by-step guide will walk you through the process, ensuring that your toilet is up and running smoothly again in no time.

Step 1: Preparation and Safety

Before you begin, gather all the necessary tools and materials. You will need a new cistern, an adjustable wrench, a screwdriver, plumber’s tape, and a sponge. Additionally, ensure that you have turned off the water supply to your toilet and have towels or rags handy to catch any water that may spill during the process.

Step 2: Emptying the Cistern

To start, flush the toilet to empty as much water as possible from the cistern. Use a sponge to soak up any remaining water. Once the cistern is empty, disconnect the water supply line located at the bottom of the cistern. Use a wrench to loosen the nut connecting the supply line and carefully remove the line.

Step 3: Removing the Old Cistern

To remove the old cistern, locate the mounting bolts on the bottom and loosen them with a wrench. Once the bolts are loose, carefully lift the cistern away from the toilet bowl. Be cautious, as the cistern can be heavy. Place the old cistern aside.

Step 4: Installing the New Cistern

Begin by applying plumber’s tape to the threaded holes in the toilet bowl. This will help prevent leaks. Carefully position the new cistern over the threaded holes and lower it onto the toilet. Align the cistern evenly and ensure that it is centered. Secure the cistern in place by tightening the mounting bolts with a wrench.

Step 5: Reconnecting the Water Supply Line

Reattach the water supply line to the bottom of the new cistern. Fit the nut onto the threaded end of the supply line and tighten it by hand. Use a wrench to ensure it is securely tightened. Open the shut-off valve to restore the water supply.

Step 6: Testing

Once the water supply is turned on, flush the toilet to check if everything is working properly. Inspect for any leaks and make necessary adjustments if needed. If everything looks good, congratulate yourself on successfully changing your toilet cistern!

By following these steps, you can easily replace a toilet cistern and avoid the hassle and expense of hiring a professional plumber. Remember to always exercise caution and if you encounter any difficulties or uncertainties, it is best to consult a plumbing expert.

    Steps to Remove the Old Cistern

    Removing the old cistern is an important step when replacing your toilet system. Follow these steps to ensure a smooth and successful removal process:

    1. Turn off the water supply

    Before you begin to remove the old cistern, turn off the water supply. Locate the shut-off valve near the bottom of the toilet on the wall or floor. Rotate the valve handle clockwise to shut off the water flow. Once the supply is completely shut off, flush the toilet to empty the cistern.

    2. Disconnect the water supply line

    4. Remove the mounting screws

    Look for the mounting screws that attach the cistern to the wall. Typically, there will be two screws located near the top of the cistern. Use a screwdriver or drill to loosen and remove these screws. Once the screws are removed, gently lift the cistern away from the wall.

    Remember to take caution when removing the old cistern as it can be heavy and fragile. Use proper lifting techniques or ask for assistance if needed. Additionally, avoid putting excessive pressure or force on any part of the cistern to prevent damage.

    By following these steps, you will be able to successfully remove the old cistern and proceed to the next steps in installing your new toilet cistern.

    Installing the New Cistern

    Read the manufacturer’s instructions that come with the new cistern carefully. Each cistern model may have specific installation requirements, so it is important to know and follow them properly.

    Here is a general outline of the installation process:

    1. Position the Cistern

    3. Attach the Flush Valve
    4. Fit the flush valve into the cistern according to the manufacturer’s instructions. Use the provided rubber gasket or sealing washer to create a watertight connection.

    5. Connect the Inlet Valve
    6. Attach the inlet valve to the bottom of the cistern. Make sure it is securely fastened and aligned with the inlet water supply pipe.

    7. Attach the Flush Mechanism
    8. Install the flush mechanism according to the manufacturer’s instructions. This may involve attaching a chain, lever, or button to the flush valve.

    9. Connect the Water Supply
    10. Use a wrench to connect the water supply pipe to the inlet valve. Ensure the connection is watertight to avoid any leaks.

    11. Adjust the Water Level
    12. Follow the instructions to adjust the water level inside the cistern. This will ensure proper flushing and prevent any overflow issues.

    13. Test the Flushing
    14. Once everything is installed, turn on the water supply and test the flushing mechanism. Check for any leaks and make sure the toilet flushes properly.

    Following these steps will help you successfully install the new cistern and restore the functionality of your toilet.

    Testing and Troubleshooting the New Cistern

    Once the new cistern has been installed, it is important to test it to ensure that everything is working correctly. This step will help to avoid any future issues and ensure proper functionality of the toilet.

    Here are some steps to effectively test and troubleshoot the new cistern:

    1. Check for Leaks:

    After installing the new cistern, it is crucial to check for any visible leaks. Carefully inspect all the connections and joints where leaks might occur. Make sure all the nuts and bolts are properly tightened to avoid any leaks.

    2. Fill the Cistern:

    You can now proceed to fill the cistern with water by turning on the water supply valve. Allow the cistern to fill completely and observe whether there are any leaks during the filling process.

    3. Test the Flush:

    Once the cistern is full, you can now test the flush mechanism. Push the flush button or lever and check if the cistern empties smoothly and that all the water is released into the toilet bowl without any issues.

    4. Adjust Water Level:

    If you notice that the water level in the cistern is too low or too high after testing the flush, you may need to adjust it. Refer to the manufacturer’s instructions on how to adjust the water level or consult a professional plumber if required.

    5. Test Multiple Flushes:

    Perform multiple test flushes to ensure consistent flushing and proper refilling of the cistern. Observe if there are any malfunctions or irregularities in the flushing process.

    6. Final Check-in the Cistern:

    Thoroughly inspect the internal components of the cistern, such as the fill valve and flush valve, to ensure that they are working correctly. The fill valve should stop filling the cistern once it reaches the desired water level, and the flush valve should completely seal off the outlet after flushing.

    By following these steps, you can effectively test and troubleshoot the new cistern, ensuring optimal performance and preventing any future issues that may arise with your toilet.
