Differentiate between an automatic and mechanical flushing cistern.

An automatic flushing cistern is a type of cistern that is equipped with sensors or timers that automatically flush the toilet after each use. This type of cistern is commonly found in public restrooms and commercial buildings to ensure proper hygiene and water conservation.

On the other hand, a mechanical flushing cistern relies on manual operation to flush the toilet. This type of cistern is typically found in residential buildings and requires the user to press a button or pull a lever to initiate the flushing process.

In summary, the main difference between an automatic and mechanical flushing cistern is the method of operation – automatic cisterns flush automatically, while mechanical cisterns require manual intervention.

Automatic Flushing Cistern:

- Flushing mechanism: Uses a sensor to detect the presence of a user, such as an infrared sensor or motion sensor.
- Flushing triggered: Automatically flushes after a preset time or when the user leaves the bathroom.
- Benefits:
- Hygienic, as it eliminates the need to touch the flush handle.
- Water-saving, as it flushes only when necessary.
- Convenient for public or heavily used restrooms.

Mechanical Flushing Cistern:

- Flushing mechanism: Requires manual activation by pressing a lever or button.
- Flushing triggered: Controlled by the user, typically when they are done using the toilet.
- Benefits:
- Simpler and more affordable to install.
- Provides the user with complete control over the flushing process.
- Suitable for most home or private restrooms.
