What is a Concealed Cistern?

A concealed cistern is a plumbing device hidden within the wall, designed to store water for flushing toilets. By integrating the cistern into the wall structure, it not only saves space but also contributes to a cleaner and more aesthetically pleasing bathroom environment. These systems are typically paired with wall-hung toilets, allowing for a modern and streamlined appearance.

Benefits of Installing a Concealed Cistern

There are numerous advantages to installing a concealed cistern, including:

1. Space Efficiency

Concealed cisterns help maximize bathroom space by eliminating bulky toilet tanks. This is particularly beneficial in smaller bathrooms where every inch counts.

2. Enhanced Aesthetics

The absence of visible plumbing fixtures allows for a cleaner and more elegant look. A bathroom featuring a concealed cistern appears modern and sophisticated.

3. Easy Maintenance

With fewer exposed components, cleaning becomes easier. Additionally, if repairs or adjustments are needed, access points are designed for convenience.

4. Noise Reduction

Concealed cisterns typically operate more quietly than traditional cisterns, contributing to a peaceful bathroom environment.

5. Water Efficiency

Many concealed cisterns come equipped with dual-flush systems, allowing users to conserve water and reduce utility bills.

Tools and Materials Needed

Before beginning the installation, gather the following tools and materials:

Essential Tools

• Drill and drill bits


• Level


• Measuring tape


• Wrench set


• Screwdriver


• Pencil for marking

Materials Required

• Concealed cistern unit


• Wall-hung toilet


• Flexi-hoses for water connections


• Wall brackets and screws


• Sealant or silicone

Step-by-Step Installation Process

Now, let’s delve into the detailed steps for installing your concealed cistern:

Step 1: Plan Your Installation

Before starting, determine the location of your concealed cistern. Consider the layout of your bathroom and the proximity to existing plumbing. Mark the appropriate height for the wall-hung toilet and cistern, typically around 400-450 mm from the floor.

Step 2: Prepare the Wall

Clear the area where the cistern will be installed. Ensure that the wall is sturdy enough to support the weight of the toilet and cistern. If you're working with drywall, consider installing additional framing to provide adequate support.

Step 3: Install the Concealed Cistern

Following the manufacturer's instructions, secure the concealed cistern to the wall using the provided brackets and screws. Ensure that it is level and firmly attached to avoid any future issues.

Step 4: Connect the Water Supply

Using flexi-hoses, connect the water supply to the inlet valve on the cistern. Make sure to check for leaks after tightening the connections.

Step 5: Mount the Wall-Hung Toilet

Attach the wall-hung toilet to the cistern according to the manufacturer's guidelines. Ensure that the toilet is aligned correctly and securely fastened to the wall brackets.

Step 6: Test the System

Once everything is connected, turn on the water supply and test the cistern for proper functionality. Flush the toilet several times to ensure everything operates smoothly and check for any leaks.

Step 7: Finish the Wall

After confirming the system works correctly, finish the wall around the cistern with tiles or wall panels, ensuring access points remain available for future maintenance.

Common Installation Mistakes to Avoid

Even experienced DIYers can make mistakes. Here are common pitfalls to watch out for:

1. Inaccurate Measurements

Double-check all measurements before cutting into walls or purchasing materials. Inaccurate measurements can lead to costly mistakes.

2. Poor Wall Support

Ensure that the wall is adequately supported. A concealed cistern can be heavy when filled with water, and insufficient support can lead to structural issues.

3. Neglecting to Test Connections

Always test water connections for leaks before sealing the wall. A small leak can cause significant damage over time.

Maintenance Tips for Your Concealed Cistern

Regular maintenance will ensure your concealed cistern operates smoothly for years to come:

1. Regularly Inspect for Leaks

Check around the cistern and toilet for leaks periodically. Early detection can prevent more significant issues.

2. Clean the Flush Mechanism

Over time, debris can accumulate in the flush mechanism. Clean it regularly to ensure optimal performance.

3. Replace Worn Parts Promptly

If you notice any signs of wear or malfunction, replace parts as needed to maintain efficiency.
