Cistern toilets have become increasingly popular in recent years due to their water-saving capabilities and improved efficiency. These toilets utilize a cistern or tank to store and release water for flushing, allowing users to control the amount of water used per flush. In this article, we will explore the various aspects of cistern toilets, including their types, benefits, and maintenance tips.

Types of Cistern Toilets

There are several types of cistern toilets available on the market, each with its own unique features and advantages. Understanding the differences between these types can help you make an informed decision when choosing a cistern toilet for your home.

1. Gravity-Fed Cistern Toilets:
– Gravity-fed cistern toilets are the most common type and operate by using the force of gravity to flush waste.
– These toilets rely on the weight of the water in the cistern to create enough pressure for a successful flush.
– They are relatively simple in design and require minimal maintenance.

2. Pressure-Assisted Cistern Toilets:
– Pressure-assisted cistern toilets use compressed air or water pressure to enhance the flushing power.
– These toilets are known for their strong flush and are often found in commercial settings.
– They are more expensive than gravity-fed toilets but offer superior performance.

3. Dual-Flush Cistern Toilets:
– Dual-flush cistern toilets provide users with the option to choose between a full flush and a half flush.
– The full flush is used for solid waste, while the half flush is suitable for liquid waste.
– This dual-flush mechanism helps conserve water by using less water for liquid waste.

Benefits of Cistern Toilets

Cistern toilets offer several benefits that make them a popular choice among homeowners and businesses alike. Here are some of the key advantages of using a cistern toilet:

1. Water Efficiency:
– One of the primary benefits of cistern toilets is their water-saving capabilities.
– By allowing users to control the amount of water used per flush, cistern toilets help conserve water and reduce water bills.
– Compared to traditional toilets that use a fixed amount of water per flush, cistern toilets offer significant water savings.

2. Environmental Friendliness:
– The water-saving nature of cistern toilets makes them environmentally friendly.
– By reducing water consumption, these toilets contribute to water conservation efforts and help protect the environment.

3. Cost Savings:
– Cistern toilets can lead to cost savings in the long run.
– While they may have a higher upfront cost compared to traditional toilets, the reduced water usage can result in lower water bills over time.

4. Improved Hygiene:
– Many cistern toilets come with features such as rimless bowls and advanced flushing systems that enhance hygiene.
– These features help prevent the buildup of bacteria and make cleaning the toilet easier.

Maintenance Tips for Cistern Toilets

Proper maintenance is essential to ensure the longevity and optimal performance of cistern toilets. Here are some maintenance tips to keep in mind:

1. Regular Cleaning:

– If you notice any leaks, promptly repair or replace the faulty components.

3. Avoid Flushing Non-Flushable Items:
– Only flush toilet paper and human waste down the toilet.
– Avoid flushing non-flushable items such as wet wipes, sanitary products, or cotton balls, as they can cause clogs and damage the toilet.

4. Maintain the Cistern Mechanism:
– Regularly inspect and maintain the cistern mechanism, including the fill valve and flush valve.
– Replace any worn-out or faulty components to ensure proper functioning.


Cistern toilets offer a range of benefits, including water efficiency, environmental friendliness, cost savings, and improved hygiene. By understanding the different types of cistern toilets and following proper maintenance practices, you can enjoy these advantages while ensuring the longevity and optimal performance of your toilet.
