Several varieties of plumbing pipes exist, all with pros and cons. Copper, for example, is durable, not prone to leaks, and has a long lifespan (50–80 years). It’s pricey, however, and in older homes may contain lead-based solder, which can contaminate drinking water. In contrast, PVC pipes are inexpensive, easy to work with, and never rust or corrode, but they can warp when exposed to very hot water.
A pipe’s purpose and longevity, as well as your budget, will determine which pipes you choose when it’s time to replace the pipes in your home. Do some research and ask the advice of a professional plumber before you decide.
