A plumber’s lifespan is affected by several factors. For example, a plumber needs to have an advanced knowledge of the science behind plumbing and the workings of appliances and pipes. He must be aware of the water pressure and gravity, and must understand how water flows through pipes to prevent leaks. In addition, a plumber needs to have insurance and a license to operate. Before hiring a plumber, be sure to check their references and customer reviews.

Another factor that affects a plumber’s lifespan is the material of the pipes. Most plumbing systems are made of metal, copper, or galvanized steel, and these materials have varying life spans. While a copper pipe can last 50 years or longer, a brass pipe can last between 40 and 70 years. Copper pipes, on the other hand, can last for as much as 80 years, but they must be replaced more often than pipes in areas where they are not as frequently used.
