Now that you have everything you need, let’s dive into the step-by-step process of fixing your leaky kitchen sink faucet:

Step 2: Disassembling the Faucet

Start by removing the decorative cap on top of the faucet handle, if present. Use a flathead screwdriver to gently pry it off. Next, use a screwdriver to remove the screw underneath the cap. With the screw removed, carefully lift off the handle to expose the faucet cartridge or valve.

Step 3: Replacing Faulty Parts

Inspect the cartridge or valve for any signs of damage, such as cracks or wear. If necessary, replace it with a new one specific to your faucet model. Additionally, check the O-rings and washers for wear or mineral buildup. These can be replaced using the appropriate replacement parts.

Step 4: Reassembling the Faucet

Once you have replaced any faulty parts, carefully reassemble the faucet in the reverse order of disassembly. Make sure the cartridge or valve is properly aligned, and the handle is securely attached. Tighten the screw beneath the decorative cap to hold the handle in place.

Step 5: Testing for Leaks

With the faucet reassembled, it’s time to test for leaks. Turn on the water supply by twisting the shut-off valves counterclockwise. Slowly turn on the faucet and check for any leaks around the handle or spout. If you notice any leaks, double-check the connections and tighten them as needed.
