5-inch (13 cm) flex suction hose with Storz fittings, mounted on an engine. Flexible suction hose (Flex suction or suction hose), not to be confused with hard suction hose in U.S., is a specific type of fire hose used in drafting operations, when a fire engine uses a vacuum to draw water from a portable water tank, pool, or other static water source.
Suction Hose. Suction hose is laid down on the suction side of pump (inlet) where the water passing through it is at a pressure either below or above that of the atmosphere. It is designed to resist internal and external pressure. It should have sufficient strength to withstand the pressure of external air when a vacuum has formed inside.
At its annual convention at Dallas, TX, the NFPA formally adopted a standard with 2 + 1 ⁄ 2-inch hose with 7.5 threads per inch as the primary standard, with additional sizes of 3 and 3.5 inches (each with 6 threads per inch) and a 4.5 inch coupling with 4 threads per inch, with the fire hydrant standard specifying one 4.5 inch port and two 2 ...

The 100 mm (4-inch) and 125 mm (5-inch) Storz couplers have been specified in NFPA 1963, Standard for Fire Hose Connections, since the 1993 edition. U.S. cities that have fire hydrants with 125 mm Storz connectors include Raleigh, NC [ 5 ] and the City of Corvallis, OR (adapter on 4-inch threaded outlet).
To reduce drafting friction and obtain a larger flow or higher lift, a larger cross-section of suction hose is employed. For example, using a five-inch (127 mm) hose, a pump that could lift 500 US gallons per minute (30 L/s) up 23 feet (7.0 m) would only be able to lift the same amount of water 12.5 feet (3.8 m) through a 3.5-inch (89 mm) hose.
