plumber Information
April 14th, 2017

Plumbers install, repair, and maintain pipes that carry water, gas, or sewage, as well as related appliances (e.g. water heaters). Plumbers work in homes, businesses, and factories. Plumbers must travel to the worksite and many are on call for emergency calls, meaning that you may be expected to work some evenings and weekends. Most localities require that a plumber be licensed to work. Plumbers in your locale may be unionized and you may need to find an apprenticeship through the union. Another possible path to becoming a plumber is to attend a technical school. The typical key performance area includes technical knowledge and skill and basic customer service skill.

You can find vacancies for plumbers in your local trade publications and newspapers, as well as online job boards that your local community frequents. The interview process can vary widely from company to company. A few common concerns include: the number of years of experience that you have; your ability to navigate the neighborhood(s) that you'll be providing service to; and your ability to speak, read, and write in English. Depending on the clientele that the company serves, you might be expected to speak another language as well. Punctuality, reliability, honesty, and diligence are valuable traits.

To prepare for the interview, think about examples that showcase your ability to meet deadlines and honor time obligations, as well as situations in which you were able to bring about a positive outcome due to your diligence and thoroughness. The plumbing profession has real impacts on public safety, so showing integrity and diligence will give your prospective employer confidence that you won't be reckless and put the company in legal danger. Adopt a polite, professional, and pleasant attitude to show that your company can trust you to be the face of the company out there in the field.
