How to Fix a Leaky Single-Handle Faucet (Ball-Valve Type) · Step 5 of 6
In this video
Reinstall the faucet components in reverse order. First, push the plastic cartridge back into the valve body, making sure to align the notches on the side of the cartridge with the corresponding slots in the valve body. Screw the bonnet nut back on hand-tight, then give it a final snug turn with the channel-lock pliers. Slide the metal collar and faceplate back on, securing the faceplate with its two screws. Finally, place the handle back on the stem—ensuring the plastic adapter is oriented correctly for proper handle motion—and tighten the handle screw.
Goal: Rebuild the Faucet
- Be careful not to over-tighten the bonnet nut or screws.
- Ensure the plastic handle adapter is installed correctly to allow the handle to turn properly. If it's on wrong, the handle's movement will be blocked.

FAQs
How can I tell if my single-handle faucet is a ball-valve type before buying a repair kit?
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.
Do I really need all the specific tools listed, or can I use alternatives for this repair?
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.
What are the most important safety precautions I should take before starting this project?
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.
How much does a typical faucet repair kit cost, and is 2 hours a realistic timeframe for a beginner?
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.
