Which type of tank is generally associated with manually activated pumps?

A gravity tank is commonly associated with manually activated pumps due to its operational characteristics. These tanks rely on gravity to generate pressure, allowing the water to flow down to the system without the need for a powered pump. Because of this reliance on gravity, users often need to manually activate pumps to initiate water flow or to maintain pressure for systems that require it, making this setup suitable for scenarios where manual intervention is necessary.

In contrast, pressure tanks are designed to maintain a specific pressure within the system and usually rely on an automatic pump that engages when the pressure drops. Fire tanks are primarily intended for emergency fire suppression systems and typically have dedicated pump systems that operate automatically or via control panels. Above-ground tanks can be linked to both manual and automatic pumping systems; their operation is more flexible and often automated.

The association of gravity tanks with manual activation reflects their design intent and operational requirements, making these tanks appropriate for situations where manual control is needed.
