How the Oasis™ Hydrant Assist Valve Works to Enhance Firefighting Operations

What is Oasis?

The Oasis Hydrant Assist Valve is a versatile 4-way valve designed to enhance firefighting operations by maximizing water supply, pressure, and flow rate. Whether used in a relay or directly from a hydrant, this innovative valve offers a wide range of features that help firefighters overcome various challenges. By providing seamless transitions between inline and boost modes, the Oasis valve ensures optimal performance in both standard and demanding scenarios. Its ability to navigate around obstructions, maintain high pressure over long distances, and function effectively with low water flow or pressure makes it an indispensable tool in firefighting.

When should you use the Oasis?

Low Hydrant Pressure Situations

If your engine’s intake pressure reads close to zero, you likely still have more water supply potential from the hydrant. Remember, hydrants are fed by large water mains, and the intake pressure at your truck might not reflect the full capacity of the hydrant.

In these cases, the Oasis allows you to maximize that extra water supply. Initially, water flows directly through the device to the attack engine. Once a boost is needed, or when your second engine arrives, you can connect the intake and discharge lines to the Oasis, engaging Mode Two to boost flow and pressure—without interrupting water flow to the fire scene.

The Oasis design ensures your crew can continue operating without the need to shut down, even when adding additional intake and discharge lines for boosting.

Long Hose Lays

When operating in rural areas or when connecting to hydrants on a different water grid, you may need to run long hose lays. Traditional setups require shutting down the line to connect additional engines for boosting, which interrupts water flow to the fireground.

With the Oasis preconnected in your LDH lay, you can connect a relay engine and boost flow without shutting down. The Oasis is installed between hose lengths, allowing water to flow straight through until the relay pumper arrives to boost the pressure and overcome friction loss from the long hose lay.

This configuration ensures that your fireground operations continue uninterrupted, and you can maintain the necessary pressure for fire suppression over long distances.

Conclusion 

The Oasis Hydrant Assist Valve keeps your crew operating efficiently on the fireground. Whether you need to tap into additional water capacity from a hydrant or overcome friction loss in long hose lays, the Oasis ensures continuous water flow without disruption. For any fire department looking to improve firefighting operations, the Oasis is an essential tool that provides reliability, flexibility, and enhanced water control.
