The use of a double-clappered siamese in rural water supply operations is often called the "rural hitch." The valve allows for the quick establishment of water supply from a tanker to an engine - assuming that the tanker has a pump capable of doing such. Sometimes, an entire incident can be managed using a simple nurse tanker operation and the rural hitch. Others times, the demand on resources requires the use of dump tanks. Regardless of the type of event, the rural hitch reduces the stress of water supply operations during those critical first 5 or 10 minutes of initial set-up.

The first arriving engine (attack engine) has layed out a 5-inch supply line trimmed out with a double-clappered siamese. The first tanker has arrived and is shown here connecting to the valve in order to supply water to the attack engine several hundred feet down the road.
