Most plumbers receive their training through an apprenticeship, which usually lasts four to five years and includes 2,000 hours of on-the-job training. Apprentices must be at least 18 years old and have a high school diploma. During this time, they learn about local codes, blueprint reading, and safety.

To prevent the need for a plumbing service, homeowners should be knowledgeable about their water system. They should know where their water main is located, how to operate the shut-off valve, and where their sewer clean-out valve is located. Knowing where these points are can help the plumber determine the problem faster.

If you need a plumber, you should make sure he is licensed. Plumbers who do not have a license risk putting your property at risk. Also, plumbers who are licensed have proven their knowledge of the local building codes. Additionally, plumbers who are licensed are insured and follow specific guidelines.

A plumber’s job includes installing pipes that supply water and gas to a home or business and carry waste away from the property. They may also be asked to cut holes in floors or ceilings. They may even be called in to hang steel supports from ceiling joists. During the installation process, plumbers must measure the pipes and cut them to fit them. Copper pipes may also need to be soldered into place.

Plumbers can repair leaking pipes, puddles, and other plumbing problems. They also work to ensure that the drainage system of a home is working properly and that the water is clean for drinking and bathing.
