How deep must an underground container for LP gas be set?

The correct depth for setting an underground container for LP gas is typically regulated to ensure safety and compliance with local codes and standards. A depth of 2 feet is commonly required because it provides an adequate buffer to protect the container from surface disturbances and environmental elements while also being deep enough to safeguard against potential hazards, such as vehicle traffic or ground movement. Setting the container at this depth helps to minimize the risk of damage and ensures proper operation of the gas system.

In many jurisdictions, this requirement is also aligned with national safety standards, which prioritize the integrity and security of LPG storage. It’s essential for anyone involved in plumbing or gas installation to understand these regulations to ensure compliance with safety practices. Proper installation at the required depth is also critical for effective drainage, as this depth assists with preventing moisture accumulation that could corrode the container or lead to leaks.

A depth of 1 foot may be insufficient as it does not provide enough protection against all potential risks. Similarly, depths of 3 feet or 4 feet, while generally safer, can be impractical and unnecessary for most installations unless specific conditions warrant it. Therefore, the requirement for 2 feet strikes a balance between safety and practicality.
