What type of components are usually included in residential sprinkler systems beside fire pumps?

In residential sprinkler systems, water storage tanks are essential components, as they provide an adequate supply of water that can be used for fire suppression. These tanks ensure that, during a fire event, the sprinkler system has a reliable water source to draw from, especially in situations where the municipal water supply may not be sufficient or accessible. Water storage tanks can be strategically placed to maintain the necessary pressure and flow rates required for effective operation of the sprinklers.

Other components mentioned, such as water heaters, water softeners, and pressure regulators, serve different functions within a building's plumbing and water management systems but are not specifically designed for or directly involved in the operation of residential sprinkler systems. Water heaters are focused on providing hot water for domestic use, water softeners are utilized to treat hard water, and pressure regulators help manage water pressure in plumbing but do not contribute directly to fire protection.
