In combination with which type of tank are manually activated pumps typically used?

Manually activated pumps are typically used in conjunction with a gravity tank because this setup allows for a straightforward and efficient means of delivering water through gravity pressure. A gravity tank relies on the principle of gravity to move water, which means that water is stored in an elevated position and can flow down via its own weight. When a manually activated pump is used with a gravity tank, it can assist in drawing out water when the tank is full or supplying additional pressure when necessary. This combination optimizes the system's performance by leveraging the natural flow dynamics provided by the gravity tank while allowing for manual control over the water delivery process.

In contrast, expansion tanks are primarily used in hydronic heating systems to manage fluid pressure changes rather than for delivering water. Submersible tanks are designed to house a pump within the tank, specifically for pumping water from a submerged position, making them less about manual activation. Chemical tanks are specialized for storing specific chemicals and may not utilize the same principles of water delivery as gravity tanks, focusing instead on different handling and safety protocols.
