Introduction to Concealed Cisterns


Installing concealed cistern accessories can seem daunting, but with the right guidance, it’s a straightforward process that can significantly enhance your bathroom’s functionality and aesthetics. Concealed cisterns offer a sleek, modern solution for toilets, hiding the plumbing behind the wall while providing a clean and uncluttered appearance. In this guide, we will explore everything you need to know to install concealed cistern accessories like a pro.


What Is a Concealed Cistern?


A concealed cistern is a type of toilet cistern that is hidden behind the wall, making it an ideal choice for modern bathroom designs. Unlike traditional cisterns that are visible above the toilet, concealed models allow for a more streamlined look. They are typically integrated with a wall-hung toilet, creating a seamless and elegant bathroom space.


Benefits of Using Concealed Cisterns


Concealed cisterns come with numerous advantages, making them increasingly popular in contemporary bathroom designs:



  • Space-saving: By hiding the cistern within the wall, you free up valuable floor space, which is especially important in smaller bathrooms.

  • Aesthetic appeal: The sleek design enhances the overall look of your bathroom, providing a cleaner and modern appearance.

  • Noise reduction: Concealed cisterns help reduce noise during flushing, creating a quieter bathroom environment.

  • Water efficiency: Many modern concealed cisterns are designed for optimal water efficiency, helping to reduce your water bills.


Essential Tools and Materials Needed


Before you begin the installation process, make sure you have the following tools and materials at hand:



  • Tools:

    • Adjustable wrench

    • Drill and drill bits

    • Screwdriver set

    • Level

    • Measuring tape

    • PVC pipe cutter



  • Materials:

    • Concealed cistern unit

    • Wall-hung toilet

    • Pipes and fittings

    • Flush plate

    • Water supply line

    • Sealing tape




Preparation for Installation


Proper preparation is key to a successful installation. Begin by following these steps:



  1. Select a Suitable Location: Identify where you want to install the concealed cistern. Ensure there’s enough space behind the wall to accommodate the cistern and any necessary plumbing.

  2. Check Plumbing Connections: Make sure that existing plumbing is suitable for a concealed cistern setup. You may need to make adjustments or call a plumber for complicated plumbing configurations.

  3. Prepare the Wall: If you’re installing in a new wall, make sure to frame it appropriately. For existing walls, check for electrical wiring or other plumbing that may interfere with the installation.

  4. Gather Materials: Ensure all materials and tools are ready and within reach before starting the installation.


Step-by-Step Installation Guide


Now that you're prepared, let's delve into the installation process itself. Follow these detailed steps to ensure a successful installation:


Step 1: Install the Cistern Frame


Begin by assembling the cistern frame according to the manufacturer’s instructions. Secure it to the wall using appropriate fasteners, ensuring it is level and stable.


Step 2: Connect the Water Supply


Attach the water supply line to the cistern. Use sealing tape on the threads to prevent leaks, and tighten connections with an adjustable wrench. Ensure the shut-off valve is accessible for future maintenance.


Step 3: Install the Cistern Unit


Position the concealed cistern unit within the frame. Follow the manufacturer's guidelines to secure it in place, ensuring it’s properly connected to the water supply line.


Step 4: Install the Flush Plate Mechanism


Attach the flush plate mechanism to the cistern. This usually involves securing it with screws. Check that the mechanism functions properly by pressing the flush plate several times.


Step 5: Connect the Toilet Bowl


Install the wall-hung toilet according to the manufacturer’s instructions. Ensure it is securely mounted to the wall and connected to the cistern. Use a level to verify it is even.


Step 6: Test the Installation


Once everything is connected, turn on the water supply and check for leaks. Flush the toilet several times to ensure everything is functioning correctly.


Step 7: Finish the Wall


After confirming that the installation is successful, finish the wall to conceal the cistern. You can use drywall or tiles, depending on your design preference.


Common Issues and Solutions


Even the most skilled installers may encounter issues. Here are some common problems and their solutions:



  • Leaking Connections: If you notice water around the cistern, check all connections for tightness and use sealing tape as needed.

  • Flush Plate Not Working: If the flush plate isn’t functioning, ensure the mechanism is properly installed and connected.

  • Weak Flush: A weak flush could indicate a blockage in the supply line. Inspect and clear any obstructions.


Maintenance Tips for Concealed Cisterns


Keeping your concealed cistern in top condition is essential for optimal performance:



  • Regular Inspections: Check for leaks and ensure all connections remain tight.

  • Clean the Flush Mechanism: Occasionally, debris can affect the flush mechanism. Regular cleaning will help maintain performance.
