What is the minimum height that a drain line from a water heater pan can terminate above ground level?

4 inches
6 inches
8 inches
10 inches

The correct answer is: 6 inches

The minimum height that a drain line from a water heater pan can terminate above ground level is specified to prevent any backflow or overflow issues that may arise from water pooling around the base of the water heater. A height of 6 inches is typically required to ensure that the drain line discharges water in a manner that prevents standing water, which could create a breeding ground for pests or encourage mold growth. By terminating at this height, the design helps to facilitate proper drainage while avoiding potential hazards associated with water damage. It is essential to follow these guidelines to maintain safety and compliance with plumbing codes. Additionally, terminating at this specified height assists in maintaining a clear and unobstructed path for water to flow away from the structure, thus preventing any risks associated with improper drainage.
