Step-by-Step Instructions to Fix a Leaky Kitchen Faucet

Follow these simple steps to stop that annoying drip and restore your faucet’s function:

1. Turn Off the Water Supply

Locate and shut off both the hot and cold water valves under your kitchen sink.

2. Block the Drain

Place a rag or stopper over the drain to prevent small parts from falling in.

3. Remove the Handle

Gently pry off the index button or cap using a pocket knife to reveal the hex screw. Use a hex key to unscrew it and remove the handle.

4. Take Off the Top Cap

Use a spanner wrench (usually included with your faucet) to loosen and remove the top cap assembly.

5. Remove the Stainless-Steel Ball

Lift the ball straight up and out from the faucet body.

6. Replace Rubber Seats and Springs

Using a pocket knife or tweezers, pull out the worn rubber seats and springs. Place new ones onto the tip of a pencil for easy positioning and insert them into the holes.

7. Reinstall the Ball and Cap

Drop the stainless-steel ball back into place, aligning its keyway with the tab inside. Then install a new rubber gasket and cam cap on top of the ball, ensuring proper alignment. Hand-tighten the cap assembly.

8. Restore Water Flow

Turn the water supply valves back on and check for leaks.

9. Tighten the Nut

Use the spanner wrench to tighten the nut slightly to add tension on the ball, improving seal and control.

10. Reattach the Handle

Replace the handle, tighten the hex screw, and press the index cover back into place.

What If Your Faucet Has a Ceramic Cartridge?

If your faucet uses a ceramic cartridge instead of a ball assembly:

• Remove the handle as before
• Pull out the ceramic cartridge
• Replace it with a new one specific to your faucet model

This method is usually quicker and just as effective.
