1 inch

1½ inches

2 inches

The minimum clearance required around the base of hot water storage tanks, specifically for safe waste pans, is typically set to prevent water from accumulating and allow for proper drainage. A clearance of 2 inches is recommended as it provides an adequate gap for any potential overflow from the tank or leaks, ensuring that the waste pan can effectively manage excess water without risk of overflowing or causing damage to surrounding areas.

This clearance also aids in the ease of maintenance and accessibility to the tank, which can be vital during servicing or inspections. A larger clearance helps ensure that any maintenance work can be carried out safely and without obstruction. As safety regulations may vary, local codes should always be verified, but the 2-inch clearance is standard in many jurisdictions to promote safety and operational efficiency around plumbing appliances.
