You can usually tell a faucet cartridge needs replacing if you notice leaks, inconsistent water temperature, low pressure, or difficulty turning the handle. Strange noises or dripping even when off are also clear signs. Observing these issues over time often confirms a worn cartridge.

The lifespan of a faucet cartridge depends on water quality, frequency of use, and the type of cartridge. On average, most cartridges last between five and ten years. Hard water can cause mineral buildup that wears out the cartridge faster. Signs that the cartridge is nearing the end of its life include a faucet that drips even after tightening, difficulty turning the handle, or inconsistent water temperature. Regular cleaning and occasional inspection can help extend the life of the cartridge and prevent unexpected leaks.

Signs of a damaged cartridge in a single-handle faucet include leaking water from the spout, difficulty controlling water temperature, inconsistent water flow, or a handle that feels stiff or loose. Unusual noises when turning the handle can also indicate the cartridge needs replacement.
