If a cold water storage cistern is installed at a height of less than 1.5 meters, what must be done?

When a cold water storage cistern is installed at a height of less than 1.5 meters, it is essential to ensure that it is securely supported. Supporting the cistern with brackets is crucial because a lower installation height can increase the risk of instability and movement due to the weight of the water it holds. Proper support helps to prevent any potential accidents such as tipping or falling, which could lead to water leaks or damage to surrounding areas. It also ensures that the cistern maintains its intended function without the risk of structural failure over time.

In this context, although covering the cistern, ensuring a larger diameter, or providing ventilation may have their own importance for different reasons such as preventing contamination or facilitating temperature control, these measures do not address the immediate concern of stability and safety associated with improper elevation. Thus, supporting the cistern effectively aligns with best practices in plumbing and safety standards.
