This step-by-step guide will show you how to do this, and more importantly, it will provide you with all you need to know, from understanding what is causing the leak to choosing the right tools and replacement parts. Let’s find out further how to fix a leaky tap like an expert.
Understanding the Potential Causes of a Leak
Before you start repairing your leak, you should understand what is causing it. In the majority of taps, leaks are caused by:
-
A soft washer or O-ring that has worn out
-
A worn or corroded screw hole (valve seat)
-
A part that is loose or faulty (in the tap mechanism)
-
A buildup of minerals inside the tap
Depending on how the tap was designed, the process of repairing it will differ slightly. However, the key principles remain consistent for most taps, including pillar taps, mixer taps and monobloc.
Tools and Materials You’ll Need
Here’s what you’ll need to successfully fix a leaky tap:
-
Adjustable wrench or spanner
-
Flathead and Phillips screwdrivers
-
Replacement washer or cartridge (as per your tap model)
-
Cloth or rag
-
Plumber's grease or petroleum jelly
-
Allen key (for some taps)
-
Bucket or bowl
Step-by-Step Guide to Fixing a Leaky Tap
Step 1: Turn Off the Water Supply
Before working on any plumbing fixture, the first step is always to turn off the water supply. You can search for shut-off valves under the sink and turn them clockwise. Then you can open the tap to drain any remaining water and release pressure.
Step 2: Plug the Drain
Use a sink plug or a rag to block the drain. This will prevent any small parts, like screws or washers from falling down the drain during the repair.
Step 3: Dismantle the Tap
-
Use tools like a screwdriver or an allen key to remove the decorative cap (if any) and unscrew the handle.
-
Once the handle is removed, you’ll see the internal components.
-
Then use an adjustable wrench to unscrew the valve or cartridge housing.
At this stage, inspect the internal parts. If you’re unsure of your tap’s internal mechanism, check the manual or search for the model on the manufacturer’s website. Essco, for instance, offers detailed documentation on faucets, making it easier for homeowners to identify and replace parts.
Step 4: Check and Replace the Washer or Cartridge
Most leaks are due to a worn-out washer or cartridge.
-
The first step is to remove the washer and check for signs of wear or damage.
-
If it's hardened, cracked or misshapen, it needs replacing.
-
For ceramic disc water taps, replacing the cartridge may sometimes be necessary.
Tip: It’s always a good idea to bring the old washer or cartridge to the hardware store to look for an exact match. If you're using Essco products, they come with standardised parts that are easy to replace and widely available.
Step 5: Lubricate and Reassemble
-
Apply plumber’s grease to the new washer or cartridge. The lubrication helps in smooth operation and prolongs the lifespan of the parts.
-
Reassemble the tap in the reverse order: cartridge or valve first, followed by the handle and decorative cap.
-
Use the wrench to tighten, but avoid overtightening, which can damage the parts.
Step 6: Turn On the Water and Test
Restore the water supply slowly. Turn on the tap and check for a leak. If you have done everything correctly, the leak should now be stopped.
What If the Tap Still Leaks?
If your tap still leaks after replacing the washer or cartridge, there could be deeper issues such as:
-
Corroded valve seat
-
Cracked tap body
-
Loose connections in the plumbing below the sink
In these instances, replacing the tap completely may be the quickest option. You could invest in quality Essco taps and save yourself the hassle of repairing the same tap over and over again. Essco taps are designed to last, employing ceramic disc technology that minimises wear and tear while providing years of smooth, drip-free operation.
Preventing Future Leaks
Here are a few quick tips to avoid recurring issues:
-
Avoid overtightening: Turning the handle too tightly can wear out washers and seals faster.
-
Use high-quality components: Poor-quality parts deteriorate quickly and can damage the fixture. Choose trusted brands like Essco.
-
Perform routine maintenance: Clean your taps regularly to avoid any minerals building up, especially in areas with hard water.
-
Install aerators: These can help regulate water pressure and reduce stress on internal tap components.
There are several additional reasons to fix a leaky tap. You can save gallons of water, not to mention money on your water bill. Repairing it is also far less of a hassle than replacing it. There is nothing complicated about fixing a leaky tap, especially if you have the right tools, have patience and use good quality products. Upgrading and replacing components are as simple as well. Using reliable brands, such as Essco, means that you will be able to have peace of mind in the future; they are made to last and require minimal maintenance. So the next time you spot a drip, don’t ignore it. Fix a leaky tap right away and save water, money and hassle.
