What is the minimum depth for safe waste pans for hot water storage tanks?

1 inch
1½ inches
2 inches
2½ inches

The correct answer is: 2 inches

The correct minimum depth for safe waste pans for hot water storage tanks is 2 inches. This depth is established to ensure adequate containment of any potential leaks or spills that may occur from the tank. A depth of 2 inches is considered sufficient to hold enough water to prevent overflow, allowing for safe drainage and reducing the risk of water damage to surrounding areas. Moreover, this specification is in place to accommodate the design and functionality of the waste pan, ensuring it can effectively capture waste while providing a safety margin against unwanted leaking. Such regulations help to maintain a safe plumbing system and protect both property and the environment from water damage. The other choices do not meet the necessary requirements for effective containment, which could lead to inadequate protection against potential leaks.
