If a hose bursts and needs to be exchanged, how many sections does it take to replace it?

When a hose bursts and needs to be replaced, it's typically necessary to consider both the section that has burst and the need to ensure that the integrity of the entire line is maintained. It often involves removing the damaged section and adding a new section, which can repair the system while still maintaining the proper flow of water.

In practical terms, if the burst occurs in a specific section, firefighters will usually need to replace that section and extend the line by adding another one to maintain functionality. This ensures the pressure and water flow are consistent, especially in emergency situations where every moment counts. Thus, replacing two sections—removing the damaged one and utilizing a new one to maintain the necessary coverage—is generally the most effective approach in firefighting scenarios.
