How To Fix a Leaking Basin Faucet?
2025-09-09
A leaking basin faucet is more than just an annoyance; it wastes water, increases utility bills, and can lead to stains or water damage on your sink. Fortunately, many common leaks can be fixed with some basic tools and a bit of DIY know-how. This guide will walk you through the process of diagnosing and repairing a leaky faucet, highlighting how the right parts and quality materials, like those from SINKY, make a lasting difference.
Diagnosing the Leak
The first step is to identify where the water is coming from, as this determines the repair approach.
1. Leak from the Spout: If water drips from the spout even when the handle is turned off, the issue is typically internal. This is often caused by a worn-out washer, O-ring, or a faulty cartridge/valve seat.
2. Leak from the Base: If water pools around the base of the faucet where it meets the sink, the O-rings or seals located under the faucet handle need replacement.
Essential Tools and Replacement Parts
Before you begin, gather the necessary tools. Having the correct replacement parts on hand is crucial for a smooth repair. For a reliable fix, we recommend using genuine SINKY replacement parts designed for our specific models of basin faucet.
Common Replacement Parts:
The parts you need depend on your faucet type (compression, cartridge, ball-type, or ceramic disk). Our factory designs its basin faucet models for easy maintenance, and many share common, durable components.
| Part Name | Material | Purpose | Why It Matters |
| Ceramic Disc Cartridge | Premium Ceramic | Controls water flow and temperature | Resists wear and provides drip-free performance for years. |
| O-Ring Seals | Buna-N Rubber | Creates watertight seals at connection points | Prevents leaks around the faucet base and handles. |
| Valve Seat | Brass | Provides a smooth surface for washers to seal against | A corroded seat will cause leaks even with a new washer. |
Step-by-Step Repair Guide
1. Turn Off the Water Supply: Locate the shut-off valves under the sink and turn them clockwise to stop the water flow. Turn the faucet handle on to release any remaining water pressure.
2. Disassemble the Faucet: Carefully remove any decorative caps on the handles to access the screws. Use the appropriate screwdriver or Allen wrench to loosen the handle screws and lift the handles off. Use an adjustable wrench to unscrew the retaining nut and pull out the internal cartridge or stem.
3. Inspect and Replace Parts: Examine the removed parts. Look for worn rubber washers, cracked O-rings, or damaged ceramic discs. It is often best to replace the entire cartridge or the set of O-rings and seals for a comprehensive fix. Our components are engineered for longevity and a perfect fit.
4. Reassemble and Test: Insert the new parts exactly as the old ones were removed. Reassemble the faucet in reverse order, ensuring all connections are snug but not over-tightened. Turn the water supply back on and slowly turn the faucet on to check for leaks.
FAQ: Fixing a Leaking Basin Faucet
Q: Why does my basin faucet leak from the handle?
A: A leak from the handle base is almost always due to degraded O-rings or seals. These rings form a watertight seal around the rotating parts of the handle. Over time, they can wear out, become brittle, or develop cracks, allowing water to escape. Replacing these O-rings is a straightforward and effective repair.
Q: I've replaced the washers, but my faucet is still dripping. What's wrong?
A: If the drip persists after replacing the washers, the problem is likely a worn or pitted valve seat. The seat is the connection point the washer presses against. If its surface becomes rough or corroded, it cannot form a seal, allowing water to pass through. Inspecting and resurfacing or replacing the valve seat is the necessary next step.
