Answer 1

To prevent contamination from cross​ connection, hose bibbs must be equipped with a check valve.

Step-by-step explanation:

To prevent contamination from cross​ connection, hose bibbs must be equipped with a check valve. A check valve is a mechanical device that allows water to flow in only one direction, preventing backflow or contamination from entering the water supply. This valve ensures that water can only flow out of the hose bibb and not back into the plumbing system.
