A leaking wash Basin Faucet is not just annoying — it wastes water, increases utility costs, and may indicate worn-out parts inside the faucet assembly. Fortunately, most leaks are simple to fix with a few basic tools and replacement components.

1. Identify the Source of the Leak

Before you start, determine where the leak is coming from.

Always inspect carefully — fixing the wrong part wastes time and may not stop the leak.

2. Tools and Materials You’ll Need

Keep a towel and bowl under the sink while working to catch any leaks.

3. Step-by-Step Repair Process

Step 1: Turn Off the Water Supply

• Locate the shut-off valves beneath the basin.

• Turn them clockwise to stop the water flow.

• Open the faucet to release remaining pressure.

Step 2: Plug the Drain

• Use a sink stopper or rag to prevent small screws or washers from falling down the drain.

Step 3: Remove the Faucet Handle

• Use an Allen key or screwdriver to loosen the handle screw.

• Gently lift or pull off the handle to expose the cartridge or valve assembly underneath.

Step 4: Inspect the Cartridge or Valve

• Check for mineral buildup, cracks, or worn seals.

• For compression-style faucets (two handles), remove the stem assembly — you’ll see a rubber washer at the bottom.

• For cartridge-style faucets (single handle), remove the entire cartridge from the housing.

Most KPTOPSHINE faucets use ceramic disc cartridges, known for their durability and long-term leak resistance — but even these can wear out after years of use.

Step 5: Replace Worn Parts

• Take the old cartridge or washer to a hardware store to ensure you get an exact match.

• Install the new cartridge, aligning it properly with the housing slots.

• Replace any O-rings or seals around the spout or handle base.

• Apply a thin layer of plumber’s grease on the new O-rings before reassembly.

Step 6: Reassemble the Faucet

• Reattach the handle and tighten the screw securely.

• Avoid over-tightening — it can damage the cartridge or strip threads.

Step 7: Turn On the Water Supply

• Slowly turn the shut-off valves counterclockwise to restore water flow.

• Test the faucet for leaks by turning it on and off several times.

• If the leak persists, double-check the cartridge seating and O-ring positions.

4. How to Repair Different Faucet Types

Always shut off water and check manufacturer diagrams — each faucet model may have slightly different internal components.

5. Prevent Future Leaks

• Avoid over-tightening handles: It wears out washers faster.

• Clean aerators and cartridges every few months to remove sediment buildup.

• Use filtered water if your area has hard water — it reduces mineral damage.

• Lubricate O-rings annually with plumber’s grease.

• Replace cartridges every 3–5 years for optimal performance.

Faucets from KPTOPSHINE use high-grade ceramic valves tested for 500,000 cycles — but even these benefit from periodic maintenance to ensure drip-free performance.
