These specialized control devices are essential components of modern water distribution systems, providing multiple outlets for water access in firefighting and other emergency scenarios. Characterized by a central hub with four independent valve connections, they allow for the simultaneous deployment of multiple hoses and equipment, increasing the volume and efficiency of water delivery at critical moments. An example of its use would be allowing two engine companies to connect to the same hydrant or allowing a supply line and an attack line to draw water simultaneously.
The strategic deployment of these units significantly improves response times and resource allocation during emergencies. Their ability to support multiple connections streamlines operations, reduces the need for multiple hydrants in close proximity, and minimizes the potential for pressure drops caused by overburdening a single water source. Historically, their development reflects an evolution in firefighting tactics, driven by the need for faster and more adaptable water delivery solutions. This has enabled fire departments to more effectively combat larger and more complex fires.
