Dry hydrants are also known as what?

The term "dry hydrants" refers to a firefighting water supply system that is primarily used to facilitate water drafting from static water sources, such as ponds, rivers, or lakes. These hydrants don't have a built-in water supply like traditional hydrants connected to a municipal water system; instead, they consist of a pipe that is installed into the water source and protrudes above the ground.

Drafting hydrants are specifically designed for this purpose, allowing firefighters to access water efficiently without relying on local water pressure. They are crucial in rural or remote areas where traditional hydrants may not be available, ensuring that firefighters can effectively utilize available water resources for fire suppression.

Understanding the function and purpose of dry hydrants clarifies why the correct answer emphasizes their role as drafting hydrants, linking directly to their operational capabilities in the firefighting context.
