A dripping kitchen mixer tap is more than a small inconvenience — it wastes water, increases utility costs, and can damage sink surfaces over time. Fortunately, fixing a leaky tap is a straightforward process when you understand its internal components and follow a systematic repair approach. With premium products from LODECE, a trusted faucet manufacturer and wholesaler, maintenance and repair become simpler and more reliable.
A kitchen mixer tap blends hot and cold water into a single stream through an internal cartridge. The main components include:
| Component | Function |
|---|---|
| Spout | Directs the mixed water flow |
| Cartridge | Controls water flow and temperature |
| O-rings | Seal the moving joints to prevent leaks |
| Handle | Operates flow and temperature control |
| Aerator | Regulates water pressure and reduces splashing |
Over time, cartridges and seals wear out due to minerals, water pressure fluctuations, or heavy daily use, leading to persistent drips even when the tap is closed.
To fix a dripping mixer tap, prepare the following:
Adjustable spanner
Allen key set
Screwdriver
Replacement cartridge or O-rings
Clean cloth
PTFE sealing tape
Using the right tools ensures precision and prevents surface or thread damage during repair.
Locate the isolation valves under the sink and turn them clockwise to stop the water flow. Open the tap to confirm that the water has been fully shut off.
Use an Allen key or screwdriver to loosen the set screw beneath the handle. Gently lift the handle to expose the cartridge housing.
Unscrew the retaining nut with a spanner. Carefully pull out the old cartridge and check for wear, cracks, or mineral buildup.
Tip: If the cartridge appears corroded or stiff, replacing it is usually more effective than cleaning it.
Examine the O-rings and washers at the tap base. If they appear dry or cracked, replace them with matching sizes. Apply a small amount of plumber’s grease for a smooth seal.
Insert the replacement cartridge into position, ensuring alignment with the tap body. Secure it with the retaining nut and reattach the handle.
Slowly open the isolation valves. Turn the handle in both directions to check for smooth operation and confirm the dripping has stopped.
Worn Cartridge: Ceramic discs lose their sealing precision over time.
Loose Connections: Vibrations from regular use can loosen the retaining nut or spout joint.
Limescale Buildup: Hard water minerals cause internal corrosion and restrict movement.
Aging O-Rings: Frequent rotation gradually reduces elasticity, allowing small leaks.
Regular maintenance, especially in hard water regions, helps prevent these issues before they escalate.
Clean Aerators Regularly: Remove and rinse the aerator every few months to prevent clogging.
Use Mild Cleaners: Avoid harsh chemicals that can damage chrome or matte finishes.
Operate Gently: Excessive force on the handle shortens cartridge lifespan.
Flush Water Lines: If your home’s water pressure is unstable, flush the lines to remove debris that could affect internal components.
