What is the primary function of gravity tanks when installed in a sprinkler system?

The primary function of gravity tanks in a sprinkler system is to ensure a reliable and adequate water supply for both domestic and fire fighting needs. These tanks take advantage of gravity to maintain water pressure, making it accessible for sprinklers in the event of a fire. In many applications, the stored water in these tanks contributes to the overall water supply for building operations, including domestic use, while also being readily available during emergencies.

Gravity tanks are designed to serve dual purposes: they support the daily water usage for the occupants and also provide a critical resource in case of a fire. The integration of such systems allows buildings to ensure they meet local fire safety regulations while also being equipped for everyday water needs. This versatility and readiness are what make the role of gravity tanks essential in a comprehensive fire protection strategy.
