What type of plumbing connection does a refrigerator require?

• A. Hot and cold water service
• B. Drainage service
• C. Cold water service only
• D. Refrigerant line service

Answer: (C)

A refrigerator typically requires a cold water service for the supply of water to its ice maker and water dispenser, if equipped. This connection ensures that the refrigerator has access to a source of chilled water, essential for producing ice and providing drinking water.

While some refrigerators may have a drain for condensation, that is not the primary requirement for plumbing connections. Hot and cold water service might apply to other appliances like dishwashers, but refrigerators only need cold water to function properly in this capacity. The refrigerant line service is specific to the refrigeration system itself, which does not involve plumbing in the traditional sense. Therefore, the correct answer focuses on the necessity of cold water service, which is a specific requirement unique to refrigerator installations.
