Ball-valve faucets typically have a single handle that pivots and rotates on top of a dome-shaped cap. When you remove the handle, you'll usually see a cap secured by screws, covering a plastic or metal ball. If your faucet has a cartridge (a cylinder with O-rings) or two separate handles, it's a different type and requires a different repair kit.

While the listed tools are ideal, the most crucial are an adjustable wrench, various screwdrivers (especially a flathead for prying), and a hex key if your handle has a set screw. A good pair of pliers is also very helpful. You might be able to substitute some specialty tools with basic equivalents, but ensuring you have the right sizes will prevent frustration and potential damage.

The absolute most critical step is to shut off the water supply to the faucet, either at the supply lines underneath the sink or the main house shut-off. Always double-check by turning on the faucet. Also, protect your work area with rags or towels to catch any residual water, and wear gloves if handling old, potentially corroded parts.

A standard ball-valve faucet repair kit usually costs between $5 and $20, making it a very affordable repair. For a beginner, 2 hours is a reasonable estimate, but allow yourself extra time, perhaps 3-4 hours, for unexpected challenges like stuck parts or identifying the correct repair kit. Rushing can lead to mistakes or damage.
