A leaking wash basin faucet is more than just an annoyance — it wastes water, increases utility bills, and can eventually stain your sink or countertop. Fortunately, most faucet leaks can be repaired with simple tools and a bit of care.
At Global Emysa, we design our faucets with durable ceramic cartridges, precision sealing components, and corrosion-resistant finishes, helping to minimize leaks and simplify maintenance. Still, if your faucet starts dripping, this step-by-step guide will help you fix it quickly and safely.
Before you begin, determine where the water is coming from:
From the spout: Likely a worn cartridge or valve seat.
From the handle base: Possibly a damaged O-ring or seal.
From the faucet base: Usually caused by loose mounting hardware or degraded gaskets.
Knowing the source will guide you to the right solution and prevent unnecessary disassembly.
Locate the hot and cold water valves under the sink and turn them clockwise to close. Open the faucet to release any remaining pressure in the lines.
Place a towel or small bucket under the pipes to catch any residual water.
Most wash basin faucets have a small set screw beneath or behind the handle:
Pry off any decorative cap using a flat screwdriver.
Unscrew the handle screw and pull the handle straight up.
Keep the parts in order to ensure proper reassembly.
This exposes the cartridge or valve assembly, which controls water flow.
For single-handle faucets, remove the cartridge by loosening its retaining nut.
For double-handle faucets, you may find rubber washers or valve seats at the bottom of the stems.
Check for cracks, stiffness, or mineral buildup. Replace any worn parts with the same model type — this ensures perfect fit and function.
Tip: Global Emysa faucets use standardized ceramic cartridges, available in both pressure-balanced and thermostatic designs for easy replacement.
Leaking around the handle or base often indicates a damaged O-ring. Remove the old rings carefully and install new ones coated with silicone-based lubricant for smoother motion and better sealing.
Also inspect the gasket under the faucet base — if it’s brittle or compressed, replace it before reinstalling the faucet.
Reinstall the cartridge, handle, and decorative components in the reverse order. Turn the water supply back on slowly, checking for leaks as you test hot and cold water flow.
If the drip persists, double-check that:
The cartridge is fully seated.
All O-rings and washers are aligned correctly.
The faucet handle isn’t overtightened.
Clean aerators regularly to prevent back pressure.
Avoid excessive handle force; ceramic valves require only gentle turning.
Check fittings once or twice a year for minor loosening.
Flush your water lines after plumbing work to clear sediment that can damage seals.
Global Emysa faucets are designed for long-term leak prevention with precision-machined brass bodies, high-quality ceramic discs, and tested sealing systems that withstand over 500,000 operation cycles.
