If you have a dripping kitchen sink mixer tap, it can be both annoying and wasteful. However, you don’t have to call a professional plumber right away. With a few simple steps, you can fix the problem yourself and save both time and money.
First, it’s important to identify the cause of the leak. In most cases, a dripping tap is caused by a worn out or faulty washer or cartridge. This can occur due to regular wear and tear, or a build-up of limescale and debris. By identifying the source of the problem, you can proceed with fixing it correctly.
To fix a dripping kitchen sink mixer tap, start by turning off the water supply. This is usually done by locating the isolation valves under the sink and turning them clockwise. Once the water supply is shut off, you can proceed with dismantling the tap. Use a wrench to loosen and remove the tap handle, then remove the cartridge or washer depending on the type of tap you have.
Inspect the cartridge or washer for any signs of damage or wear. If you notice any cracks, tears, or excessive wear, it’s recommended to replace them with new ones. Clean the cartridge or washer thoroughly by removing any limescale or debris. Once cleaned, reassemble the tap carefully, ensuring all components are securely tightened.
After reassembling the tap, turn the water supply back on and check for any leaks. If the tap is still dripping, it may indicate a more serious problem and you may need to consult a professional plumber. However, in most cases, replacing the cartridge or washer will solve the issue and your kitchen sink mixer tap will be drip-free once again.
Remember, regular maintenance and cleaning can help prevent future leaks and prolong the life of your tap. By fixing the problem yourself, you can save time, money, and the hassle of dealing with a dripping tap.
Causes of Dripping Kitchen Sink Mixer Taps
There are several common causes for a dripping kitchen sink mixer tap. Understanding these causes can help you identify and fix the problem. Here are some of the most likely culprits:

By replacing the worn out O-ring, you should be able to fix the dripping kitchen sink mixer tap and prevent any further water wastage or damage.
Loose Valve Cartridge
If your kitchen sink mixer tap is dripping, one possible cause could be a loose valve cartridge. The valve cartridge is the component responsible for controlling the flow of water in your tap.
To fix a loose valve cartridge, follow these steps:
Step 1: Turn Off the Water Supply
Before you start working on your tap, it’s important to turn off the water supply. Look under your sink and locate the shut-off valves for the hot and cold water pipes. Turn both valves clockwise to shut off the water.
Step 2: Remove the Tap Handle
Use a screwdriver or an Allen wrench to remove the screw that holds the tap handle in place. Once the screw is removed, gently pull the handle away from the tap.
Step 3: Tighten the Valve Cartridge
Underneath the handle, you’ll find the valve cartridge. Use an adjustable wrench to carefully tighten the cartridge by turning it clockwise. Be cautious not to overtighten, as it may cause damage to the cartridge.
Step 4: Reassemble the Tap
Once the cartridge is tightened, reattach the tap handle by inserting the screw and tightening it securely. Make sure the handle is properly aligned with the tap before tightening the screw.
Finally, turn on the water supply by turning the shut-off valves counterclockwise. Test the tap to see if the dripping has stopped. If the problem persists, you may need to replace the valve cartridge.
Remember, if you’re unsure or uncomfortable working with plumbing fixtures, it’s always best to seek professional help. They will have the necessary expertise to diagnose and fix the issue with your kitchen sink mixer tap.
Corroded Valve Seat
If you have checked the other possible causes for a dripping kitchen sink mixer tap and none of them seem to be the issue, it is possible that the valve seat has become corroded. The valve seat is located inside the tap body and acts as a sealing surface for the washer. Over time, minerals and sediments in the water can build up and cause corrosion.
In order to fix a corroded valve seat, you will need to disassemble the tap. Start by turning off the water supply to the tap and closing the drain. Use a wrench or pliers to remove the handle and the cover plate. Once those are removed, you should be able to access the cartridge or valve assembly.
Next, carefully remove the cartridge or valve assembly and inspect the valve seat. If you see any signs of corrosion, you will need to clean or replace it. To clean the valve seat, use a clean cloth or a small brush to remove any buildup or debris. If the corrosion is severe, you may need to replace the valve seat.
Installing a New Valve Seat
If you need to replace the valve seat, make sure you purchase the correct size and type for your tap. It is essential to match the new valve seat exactly to ensure a proper fit and prevent leaks.
To install the new valve seat, follow these steps:
- Apply a small amount of plumber’s grease or lubricant to the new valve seat.
- Insert the valve seat into the tap body, making sure it is aligned correctly.
- Tighten the valve seat using a wrench or pliers, but be careful not to overtighten as this can cause damage.
- Reassemble the tap by attaching the cartridge or valve assembly, cover plate, and handle.
- Turn on the water supply and check for any leaks. If there are no leaks, your kitchen sink mixer tap should now be drip-free!
Remember to clean out any excess debris or sediment from the tap before reassembling, as this can cause future issues. Regular maintenance and cleaning of your kitchen sink mixer tap can help prevent corrosion and prolong its lifespan.
Faulty Ceramic Disc
The ceramic disc within a kitchen sink mixer tap is a crucial component that controls the flow of water. Over time, this disc can become faulty, causing the tap to drip.
To fix a faulty ceramic disc, follow these steps:
- Turn off the water supply to the tap. This is typically done by closing the isolation valves located under the sink.
- Use a screwdriver or an Allen key (depending on the tap design) to remove the handle of the tap.
- Locate the ceramic disc cartridge, which is usually positioned beneath the handle. Remove the cartridge by unscrewing or pulling it out, again depending on the tap design.
- Inspect the ceramic disc for any signs of damage, such as cracks or chips. Replace the disc if necessary.
- Clean the cartridge housing thoroughly to remove any debris or mineral deposits that may affect the disc’s performance.

- Turn on the water supply and test the tap for any leaks. If the tap is still dripping, repeat the process or consider contacting a professional plumber for assistance.
Regular maintenance is essential to prevent issues with the ceramic disc and ensure the longevity of your kitchen sink mixer tap. It’s important to check for any signs of wear and tear and address them promptly to avoid more significant problems in the future.
Broken Tap Spout
If your kitchen sink mixer tap is dripping from the spout, it could indicate a broken tap spout. The tap spout is the part that extends over the sink and allows water to flow out. Over time, the spout can become loose or develop cracks, causing water to leak when the tap is not in use.
To fix a broken tap spout, follow these steps:
- Turn off the water supply to the tap. You can usually find the isolation valve under the sink.

- Tighten the fixing screw to secure the tap spout in place.
- Turn on the water supply and check for any leaks. If the tap is still dripping, you may need to consult a professional plumber to further diagnose the issue.
Remember to always take necessary precautions when working with plumbing fixtures and turn off the water supply before attempting any repairs. If you are unsure about any steps, it is best to seek professional help to avoid causing further damage or injury.
Water Pressure Issues
If you are experiencing water pressure issues with your kitchen sink mixer tap, there are a few possible causes that you can check for:
- Clogged aerator: The aerator is a small screen located at the end of the faucet spout. Over time, it can become clogged with mineral deposits, reducing water flow. To fix this, unscrew the aerator and clean it by soaking it in vinegar overnight. Rinse it thoroughly before reattaching it to the faucet.
- Blockage in the water supply lines: If your water pressure is low throughout the kitchen, the issue may be with the water supply lines. Check for any kinks or blockages in these lines. If you find any, straighten the kinks or remove the blockages to restore water pressure.
- Water shut-off valves not fully open: Make sure the water shut-off valves underneath the sink are fully open. If they are partially closed, it can restrict the water flow and result in low water pressure. Turn the valves counterclockwise to ensure they are fully open.
- Water pressure regulator issues: If your home has a water pressure regulator, it may need adjusting. Locate the water pressure regulator, which is typically located near the main water shut-off valve. Use a screwdriver to adjust the pressure to the appropriate level according to the manufacturer’s instructions.
- Plumbing system issues: If none of the above solutions worked, there may be a problem with your plumbing system. It could be a clog or a leak somewhere in the pipes. In this case, it is best to contact a professional plumber to diagnose and resolve the issue.
By checking and addressing these possible causes, you can effectively troubleshoot and fix water pressure issues with your kitchen sink mixer tap.
