D. water gap

Final answer:

Vacuum breakers prevent back-suction, cross-connections need protection, and wastewater inhibitors maintain water safety.


Explanation:

Vacuum breakers are necessary in plumbing connections to prevent back-suction, maintaining water quality and preventing contamination. They work by allowing air to enter the system, breaking the vacuum created by water flow.

Cross-connections between two-threaded faucets are safeguarded by approved vacuum breakers to ensure water flows in the right direction and prevent contamination.

Having a wastewater inhibitor is important to prevent wastewater entering the main water supply, keeping the water clean and safe for use.
