How often should faucets be replaced?

How often faucets should be replaced depends on quality, water quality, usage, and maintenance, but typically residential faucets should be replaced every 10 to 20 years, while commercial-grade faucets like Chicago Faucets can last 20 to 30 years. Builder-grade faucets like Glacier Bay last 5 to 10 years before cartridge fails, finish wears, or leaks. Mid-range residential faucets like Delta and Moen last 15 to 20 years, with cartridges needing replacement every 10 to 15 years but faucet body lasting longer if maintained. High-end faucets like Kohler, Grohe, Hansgrohe, and Brizo last 15 to 25 years with proper care. Commercial-grade faucets like Chicago Faucets and Symmons, made in USA from solid brass with Quaturn cartridges tested to 1 million cycles, last 20 to 30 years in heavy-use commercial environments and even longer in residential. Signs you need replacement include persistent dripping after cartridge replacement, low water pressure due to internal corrosion, visible corrosion or finish peeling, difficulty turning handle, or outdated style. You can extend faucet life by cleaning with mild soap, avoiding harsh chemicals, fixing leaks promptly, and using water softener for hard water. So replace faucets every 10 to 15 years for builder-grade, 15 to 20 for mid-range, 20 to 30 for commercial-grade, with Chicago Faucets lasting longest.
