The wet pipe system is the most commonly installed fire protection system due to its simplicity and reliability. In this type of system, water is stored within the pipes and is readily available to flow out of the sprinkler heads when activated by heat from a fire. This immediate response is critical in suppressing fires effectively.

Wet pipe systems are typically less complex than other types of fire suppression systems, which often require additional components or steps to release and distribute the extinguishing agent. For example, deluge systems require the deployment of water only after the system is activated, which might not be as quick as a wet pipe system. Preaction systems also add an additional layer of complexity with their need for an initial detection phase before water is released, while foam water sprinkler systems are specialized and not as widely used across general applications.

The ease of maintenance and lower installation costs make wet pipe systems a favored choice for various types of buildings, both commercial and residential. Thus, their widespread adoption is a direct result of their proven efficiency and effectiveness in fire protection.
