What does a wye fitting do in hose operations?

A wye fitting serves a specific function in hose operations by allowing one hose to branch off into two separate hoses. This is particularly useful in firefighting scenarios when multiple lines need to be supplied from a single source, enabling firefighters to attack multiple points of a fire simultaneously or to provide water coverage over a wider area.

The design of the wye fitting typically features a single inlet with two outlets, which can be connected to two hoses. This functionality allows for efficient distribution of water, making it an essential tool in managing hose lines during firefighting operations. The use of a wye fitting can enhance operational flexibility and effectiveness in combating fires.

In contrast, other options do not accurately describe the role of a wye fitting. For example, a fitting that turns two hoses into one would be a different type of connector, and increasing water pressure would involve other devices such as pumps rather than a wye fitting. Additionally, filtering water does not pertain to the wye fitting's purpose; rather, any filtration would generally occur upstream in the water supply system.
