Do you need to be a genius to become a plumber? The answer is no. All you need is a high school diploma or equivalent. You must also demonstrate proficiency in basic mathematics and algebra. Additionally, the job requires physical strength and stamina, so having a healthy back, shoulders, and knees is essential.
Many people in the plumbing industry got there by accident. They didn't grow up in a family plumbing business, or if they did, they didn't end up in plumbing. It's just one of those things; when the opportunity arises, you're helping a friend, and the next thing you know you've been doing it for a year. Then, you discover that it is a lifelong trade and skill.
If you're considering taking a plumbing and heating class for three years, it can be worth it. For example, I was fired from my service technician position due to company closure after 10 years. At 36 years old, I was thinking about changing careers to plumbing. So, if you're looking for a career change or just want to learn something new, plumbing can be an excellent option.
You don't need to be a genius; all you need is the right attitude and willingness to learn.
