Breeching Inlet

A breeching inlet is a fire brigade connection that allows firefighters to pump water into a building's dry riser, hydrant, or sprinkler system during an emergency. It is typically installed at ground level and provides an external water supply point when the building's internal water source is insufficient or unavailable.

A breeching inlet enables fire service personnel to boost water supply to a building's firefighting system during a fire emergency. By connecting fire engines directly to the inlet, firefighters can maintain adequate water pressure and flow to upper floors, hydrant systems, and sprinkler networks.

A 4" x 2-way breeching inlet has two firefighter hose connections, while a 6" x 4-way breeching inlet provides four connections for higher water flow capacity. The 2-way model is commonly used in smaller buildings, whereas the 4-way version is preferred for high-rise, commercial, and industrial facilities with greater firefighting demands.

A 6" x 4-way breeching inlet is typically used in large buildings that require higher firefighting water flow and pressure. Its four inlet connections allow multiple fire engines or hoses to supply water simultaneously, making it suitable for high-rise buildings, warehouses, airports, and industrial facilities.

A breeching inlet is usually installed outside a building at an easily accessible location for fire brigade personnel. Ground-level installation allows firefighters to quickly connect hoses and pump water into the building's fire protection system during an emergency.

A breeching inlet typically includes inlet connections, non-return valves, drain valves, blank caps, chains, and a flanged outlet connection. These components help ensure reliable water flow, prevent backflow, and protect the system from contamination when not in use.

A non-return valve prevents water from flowing back through the breeching inlet once the firefighting system is pressurized. This helps maintain system integrity, protects firefighting equipment, and ensures water flows in the intended direction during emergency operations.

Yes, breeching inlets are most commonly installed as part of dry riser systems in multi-storey buildings. They allow firefighters to charge the normally dry pipework with water from fire service pumps, delivering water to upper levels during firefighting operations.

Quality breeching inlets should comply with recognized fire protection standards to ensure performance, durability, and compatibility. Many internationally approved models are manufactured in accordance with standards such as BS 5041, BS 336, and related fire protection specifications.

Breeching inlets should be inspected regularly to ensure they remain accessible, operational, and ready for emergency use. Routine inspections should verify inlet connections, non-return valves, drain valves, caps, signage, and the overall condition of the assembly to maintain reliable firefighting performance.
