A single flush cistern is a type of toilet cistern that uses a single button or lever to release a fixed amount of water, typically 6-9 liters, to flush the toilet bowl. This type of cistern is commonly found in homes and buildings, and is typically more affordable and easier to install than dual flush cisterns.Single flush cisterns are relatively straightforward to use, as they only require one button or lever to operate. However, they can be less water-efficient than dual flush cisterns, which offer the option of a lower water volume flush for liquid waste.
To optimize the water efficiency of a single flush cistern, it's important to choose a toilet with a low water consumption rating, typically 4.5 liters or less per flush. Regular maintenance, such as checking for leaks and ensuring the flush mechanism is working properly, can also help conserve water and prevent unnecessary water waste.
