A mechanical engineer and a plumber are two distinct professions that require different skill sets and training.

A mechanical engineer typically holds a bachelor’s degree in mechanical engineering and is responsible for designing, developing, and testing mechanical systems, including heating and cooling systems, power generation systems, and transportation systems. They may also work in research and development, design, or manufacturing. They may also work in related areas such as building services engineering and HVAC design, which would have crossover skills with plumbing but not be specifically qualified as plumber.

On the other hand, a plumber is a skilled tradesperson who specializes in the installation, maintenance, and repair of plumbing systems. They are responsible for installing and maintaining pipes, fixtures, and appliances that are used for water distribution and waste management. This can include anything from fixing a leaky faucet to installing a complex sewage treatment system. Plumbers typically learn their trade through apprenticeships or vocational training programs and are licensed by the state in which they work.

While a mechanical engineer may have a strong understanding of the principles of fluid dynamics and thermodynamics, which are relevant to plumbing, they may not have the hands-on experience or training that a plumber has. Conversely, a plumber may not have the in-depth knowledge of engineering principles and complex systems that a mechanical engineer possesses. So, While a mechanical engineer may have some knowledge and skills that could be useful in a plumbing role, they would not be considered a qualified plumber without proper training and experience.

Additionally, a mechanical engineer would have to go through the process of gaining license and certification as a plumber in that specific jurisdiction to be able to work as plumber.

In summary, while a mechanical engineer and a plumber may have some overlap in their knowledge and skills, they are distinct professions that require different training and qualifications. A mechanical engineer may be able to work in some areas that overlap with plumbing, but they would not be considered a qualified plumber without proper training and experience.
