What is the recommended action when encountering a hose line over 1000 feet?

When dealing with a hose line that exceeds 1000 feet, implementing additional pumps for water relay is the most effective and recommended action. This approach is crucial because longer hose lengths can lead to significant friction loss, which decreases the pressure and flow of water at the nozzle. By utilizing additional pumps in a relay system, the necessary pressure can be maintained throughout the length of the hose, ensuring that adequate water flow reaches the intended location.

The use of additional pumps helps to counteract the challenges associated with long distances, as each pump can help to boost the pressure adequately and manage the increased demand caused by friction loss. This strategy is particularly important in firefighting operations, where maintaining effective water delivery can be critical for controlling and extinguishing fires.

While increasing pump pressure could seem like a viable solution, it may not be sufficient on its own, especially given that each additional 100 feet of hose can significantly impact pressure levels. Adding more nozzles can lead to further difficulties in managing flow and may also decrease pressure rather than increasing it. Switching to a smaller diameter hose would potentially create even more friction loss and reduce the amount of water delivered, thereby worsening the situation rather than helping it. Each of these alternatives lacks the effectiveness and reliability of implementing additional pumps in
