How to Fix a Leaky Single-Handle Kitchen Faucet (Ball-Valve Type) · Step 3 of 7
In this video
After removing the cover, you will see the valve inside its housing. To access the internal mechanism, you need to remove the large, round cap on top. This is typically a screw-on cap. Use a tool like an Allen wrench, pry bar, or large pliers to fit into the notches on the cap and turn it counter-clockwise to unscrew and remove it. As you take the cap off, pay attention to the rubber O-ring underneath, as it must be in good condition and replaced properly for a good seal.
Goal: Access the internal valve mechanism
- The cap may be tight. Use a suitable tool for leverage, but be careful not to crack the plastic cap.
- Note the position of the O-ring. It needs to be clean and properly seated during reassembly to prevent sewer gas leaks.

FAQs
How difficult is this repair for a beginner, and how long should it take?
This repair is rated beginner-friendly, but requires patience and attention to detail. For a first-timer, expect to spend 1-2 hours from start to finish, including gathering tools and testing. The cost is usually just the repair kit, which is significantly cheaper than replacing the entire faucet.
How can I tell if my leaky faucet is a 'ball-valve type' and ensure I buy the correct repair kit?
Ball-valve faucets typically have a single handle that rotates and tilts to control both temperature and flow. To confirm, carefully remove the handle; if you see a cap underneath that unscrews to reveal a metal or plastic ball, seats, and springs, it's a ball-valve type. Always check your faucet's brand and model (often Delta) to find the exact replacement kit, like the 'DANCO Repair Kit for Delta W/212SS Ball 86971'.
What should I do if I can't find the water shut-off valves under my sink, or if they're stuck?
If you can't locate the hot and cold shut-off valves under the sink, you'll need to turn off the main water supply to your entire house, usually located in the basement or near the water meter. If the under-sink valves are stuck, try gently using an adjustable wrench to turn them, but avoid excessive force to prevent damage. If they still won't budge, it's safer to use the main shut-off or call a professional.
I replaced the parts, but my faucet is still leaking. What could be the issue?
First, double-check that all components, especially the new springs, seats, and the ball, are installed correctly and oriented properly according to the repair kit instructions. Ensure the new O-rings are lubricated with plumber's grease and seated perfectly without any twists or pinches. Sometimes, either over-tightening or under-tightening the cap can cause leaks, so adjust carefully.
