Which boiler license class allows for the repair of non-boiler external piping?

The Class P boiler license is specifically designated for individuals who are authorized to perform work related to plumbing, including the repair and maintenance of non-boiler external piping. This license encompasses the broader scope of plumbing systems, which may include various types of piping that do not involve the boiler itself but are essential for the overall hydronic and thermal systems.

Understanding the specific licensing requirements is crucial for ensuring that individuals perform tasks within their qualifications and expertise. The Class P license is particularly focused on the intricacies of plumbing, making it the appropriate choice for someone tasked with the repair of external piping that is not directly associated with boiler operations.

In contrast, other classes either pertain specifically to boiler operations or have different scopes of work, which may not include the authority to repair non-boiler external piping. This distinction underscores the importance of obtaining the correct license to perform specific repair tasks within the plumbing and heating industry.
