The toilet cistern, an essential bathroom component, ensures your toilet’s efficient and effective functioning. Also known as the tank, the cistern stores and releases water for flushing, making it a critical factor in maintaining a hygienic and comfortable bathroom environment.

Choosing the perfect toilet cistern can be challenging with a wide array of types, styles, and features available on the market. However, by understanding the different options and considering factors such as your bathroom layout, water efficiency, and design preferences, you can make an informed decision that will enhance the functionality and aesthetics of your bathroom.

In this comprehensive guide, we’ll explore the various types of toilet cisterns, discuss the essential factors to consider when selecting them and provide expert insights to help you choose the ideal cistern for your needs.

Types of Toilet Cisterns:

Close-Coupled Cisterns

These cisterns are directly mounted on top of the toilet bowl, forming a single unit. They are a popular choice for their compact design and easy installation.

Wall-Hung Cisterns

As the name suggests, wall-hung cisterns are mounted on the wall above the toilet bowl. They offer a sleek and modern look, making them ideal for contemporary bathroom designs.

Concealed Cisterns

These cisterns are hidden within the wall, providing a minimalist, streamlined appearance. They are perfect for bathrooms with limited space or where a clean, uncluttered look is desired.

Low-Level Cisterns

Low-level cisterns are positioned near the toilet bowl, with a short pipe connecting the two. They are a traditional option often found in older properties or period-style bathrooms.

High-Level Cisterns

These cisterns are mounted high on the wall, with a long flush pipe leading down to the toilet bowl. They add a vintage charm to the bathroom and are popular for traditional or retro-style decors.

What Should You Consider When Choosing a Toilet Cistern

First, consider your bathroom’s layout and available space. Wall-hung and concealed cisterns are ideal for smaller bathrooms, as they maximise space and create a clean, streamlined appearance. For standard bathroom layouts, close-coupled cisterns are a suitable choice, as they are directly mounted on the toilet bowl and offer a more traditional look.

Water efficiency is another crucial factor to consider when selecting a cistern. Choosing a water-efficient model can significantly reduce water consumption and minimise environmental impact. Look for cisterns with dual-flush systems, which allow you to choose between a full flush for solid waste and a half flush for liquid waste, saving water with each use.

The material and durability of the cistern are also important considerations. Toilet cisterns are typically made from either plastic or ceramic. While plastic cisterns are lightweight and less expensive, ceramic cisterns are known for their durability and resistance to stains and odours. Consider your priorities and budget when deciding between these two materials.

Another key factor to remember is compatibility with your existing toilet bowl. Ensure the cistern you choose is the correct size, shape, and mounting style to guarantee a proper fit and efficient functioning.

Measuring your current toilet bowl and noting its style will help you narrow your options and select a cistern that seamlessly integrates with your bathroom.

Finally, it’s essential to determine your budget before making a purchase. While some cisterns may have a higher upfront cost, they can provide long-term savings through water efficiency and durability. Investing in a high-quality, water-efficient cistern can help you save money on your water bills, making it a smart financial decision in the long run.

Water Efficiency and Environmental Impact

As said before, look for models equipped with dual-flush technology. This innovative feature allows you to choose between a full flush for solid waste and a half flush for liquid waste, saving water with each use.

Using only the necessary amount of water per flush can dramatically decrease your overall water consumption without compromising hygiene or performance.

Many countries have implemented water efficiency regulations and labelling schemes to help consumers make informed choices. For example, in Australia, the Water Efficiency Labelling and Standards (WELS) scheme rates toilet cisterns based on their water efficiency in Australia. The WELS label displays a star rating, with more stars indicating higher water efficiency.

Cistern Installation and Maintenance

The installation process for toilet cisterns varies depending on the type of cistern you choose. Close-coupled and low-level cisterns are generally easier to install, as they are directly mounted on or near the toilet bowl. These cisterns often come with comprehensive installation instructions and can be fitted by a confident D.I.Y. enthusiast or a professional plumber.

On the other hand, wall-hung and concealed cisterns require a more complex installation process. These cisterns are mounted within the wall, necessitating specialised tools and knowledge of the plumbing system.

Man Installing Toilet Cistern

It is highly recommended that you engage the services of a qualified plumber to ensure proper installation and prevent potential issues.

Regular maintenance is essential to keep your toilet cistern in top working condition once installed. One of the most important aspects of cistern maintenance is cleaning. Over time, dirt, grime, and mineral deposits can accumulate inside the cistern, leading to decreased efficiency and potential damage to the internal components.

To combat this, it is recommended that you clean your cistern at least twice a year using a mild cleaning solution or a mixture of vinegar and water. This will help prevent debris build-up and ensure that your cistern continues to function smoothly.

In addition to regular cleaning, inspecting your toilet cistern for leaks or damage is crucial. Even a small leak can waste significant water over time, leading to higher utility bills and potential water damage to your bathroom. Periodically check the cistern for any signs of cracks, leaks, or faulty seals, and address any issues promptly. If you notice any problems or are unsure about the cause, don’t hesitate to contact a professional plumber for assistance.

Common Problems and Troubleshooting:

Even with proper installation and maintenance, toilet cisterns can experience issues that affect their performance and efficiency. Some common problems include:

Installing Toilet Cistern Tank

Noticing A Leak?

A leaking cistern can waste water, increase utility bills, and damage your bathroom. A faulty flush valve, a damaged fill valve, or a cracked cistern may cause it. Tightening connections or replacing worn-out seals can often resolve the issue, but if the leak persists, contact a professional plumber.

Poor Flushing Performance

If your toilet cistern is not flushing correctly, it could be due to a clogged rim jet, incorrect water level, or a damaged flush valve. Adjust the water level according to the manufacturer’s instructions and inspect the rim jet and flush valve for obstructions or damage. If the problem persists, seek professional assistance.

Noisy Refilling

After flushing, a loud hissing or vibrating sound from the cistern may indicate a problem with the fill valve, such as a partially closed supply line, a damaged fill valve, or high water pressure. Check the supply line for kinks or obstructions and ensure it’s fully open. If the issue persists, the fill valve may need to be replaced, or a pressure-reducing valve may be necessary.

While many common toilet cistern problems can be resolved with simple troubleshooting steps, some issues may require the expertise of a professional plumber.

Get It Right The First Time!

Choosing the right toilet cistern is an important decision that can significantly impact your bathroom’s functionality, efficiency, and aesthetics. You can select a cistern that meets your needs and preferences by considering factors such as bathroom layout, water efficiency, material, compatibility, style, and budget.

Remember to prioritise water conservation, opt for a reputable brand, and ensure proper installation and maintenance to enjoy a reliable and long-lasting toilet cistern.
