A dripping faucet usually needs a new cartridge, washer or O-ring, while weak or uneven flow is often a clogged aerator or mineral scale inside the valve. In Phoenix, hard water is behind a lot of both. Call the number on this page to be connected with a local plumber in Phoenix who can repair the faucet or install a new one.

Why Phoenix faucets wear out
The City of Phoenix water quality report lists total hardness of 10 to 17.6 grains per gallon. As that water passes through a faucet, minerals settle on cartridges, seats and aerator screens. Over time the scale roughens the surfaces that are supposed to seal, so the faucet starts to drip, the handle stiffens, or the stream turns weak and splashes. White crust around the spout and handle base is the visible sign of the same buildup inside.
Common faucet problems
- Drip from the spout: a worn cartridge, washer or valve seat.
- Water around the handle: a failed O-ring or cartridge seal.
- Low or sputtering flow: a clogged aerator, a scaled cartridge, or a supply line or shutoff valve narrowed by deposits.
- Stiff or grinding handle: mineral buildup on the cartridge.
- Puddle in the cabinet: a loose or worn supply line, or a leak at the faucet base.
- Pull-down sprayer leaks: a worn hose or a failing connection under the sink.
Check the shutoff valves too
The small valves under the sink are easy to forget until you need them. In hard water they can seize open or start weeping once they are finally turned. A plumber replacing a faucet will often recommend replacing old shutoff valves and supply lines at the same time, which avoids a second visit later.
Outdoor hose bibs
Exterior faucets take the most punishment in Phoenix. Intense summer sun bakes washers and packing, and scale builds up quickly. Freezing nights are rare but real, and an exposed hose bib or pipe can crack during one. A leaking hose bib wastes water out of sight, especially if it feeds irrigation. If a backflow assembly is installed on an irrigation line, it falls under the City's backflow prevention program and annual testing requirements.
Repair or replace
If the faucet is in good condition and parts are available, a new cartridge or a cleaned-up valve usually fixes it. Replacement makes more sense when the body is corroded, the finish is pitted, or the model is discontinued. Cost depends on the faucet brand and parts, whether shutoffs and supply lines are replaced, and how hard the space under the sink is to reach.
A whole-house softener reduces how quickly scale returns. It is a separate project, but it is worth discussing if your faucets wear out on a regular schedule.
