The answer to 'how long does faucet last' is that a typical faucet will last between 10-20 years with proper care and maintenance. Faucets are exposed to a lot of wear and tear from daily use, as well as the effects of water minerals and pressure. With regular cleaning, fixing any leaks promptly, and replacing washers or cartridges when needed, a quality faucet can provide reliable service for many years.
However, factors like the type of faucet, quality of materials, and frequency of use can all impact the lifespan. Cheaper, lower-quality faucets may only last 5-10 years, while high-end, solid brass faucets can last 20+ years with proper care. It's also important to consider the faucet's warranty, which can provide insight into the expected lifespan.
