5 Ways to Fix a Leaking Tap

Leaking taps are a common issue in many households, often leading to wasted water and increased utility bills.

Not only is a dripping tap annoying, but it also contributes to water wastage, which is particularly concerning in water-conscious Australia. Addressing a leaking tap promptly can help conserve water and save you money.

In this article, we will explore five effective methods to fix a dripping tap. Most of these straightforward techniques can be carried out with basic tools and a bit of patience, allowing you to resolve the issue without needing to call a professional plumber.

However, do not hesitate to contact local plumbing services if you’re in need of assistance.

1. Tightening the Tap

To tighten a leaky tap, you will need a few basic tools: an adjustable spanner, a wrench, and possibly a screwdriver. These can all be found at your local hardware store. These tools will help you access and adjust the tap components effectively.

Ensure the water supply to the tap is turned off at the water main to avoid any water spillage. Use the spanner or shifting wrench to remove the tap handle and tap the bonnet, exposing the internal mechanism. Carefully tighten the valve seat or spindle inside the tap using the spanner. If the leak persists, the issue might be with the washer or another component, requiring further attention.

When tightening the tap, be cautious not to overtighten, as this can damage the internal components or cause additional leaks. After tightening, reassemble the tap body and turn the water supply back on to check if the leak is resolved.

If the tap still drips, it may be necessary to seek professional help to prevent water damage to your bathroom or laundry basin.

2. Replacing the Washer

One of the most common causes of a leaking tap is a worn-out washer. Replacing it can usually fix the drip quickly and efficiently.

Here’s how to do it:

• Turn off the water supply: Before you start, make sure the water supply to the tap is completely shut off. This is typically done at the valve under the sink or the main water valve for your home.
• Plug the drain: Use a sink plug or a rag to block the drain. This prevents any small parts, like screws or the washer itself, from accidentally slipping down the drain.
• Remove the tap handle: Unscrew the handle from the tap. You might need a screwdriver or an Allen key, depending on the tap design. Carefully set aside the handle and any screws.
• Take out the old washer: Once the handle is off, you’ll see a nut holding the stem in place. Unscrew this nut and remove the stem. The washer is usually at the bottom of the stem − take it out and inspect it for wear.
• Install the new washer: Place a new washer that matches the size and type of the old one. Ensure it sits snugly in place.
• Reassemble the tap: Reverse the disassembly steps. Reattach the stem, screw the nut back in, and then replace the handle.
• Test your work: Turn the water back on and check the tap. There should be no more leaks.

Replacing the washer is a straightforward fix that can extend the life of your tap and save water.

3. Replacing the O-Ring

The O-ring is a small but crucial component that helps seal the tap and prevent leaks around the spout. Over time, O-rings can wear out or become damaged, leading to dripping taps. Knowing how to replace O-rings can save you from more significant plumbing problems.

Begin by turning off the water supply to the tap to drain any water left. Use a spanner to remove the tap handle and the decorative cap, exposing the O-ring. Carefully slide off the old O-ring and replace it with a new one of the correct size. Ensure the new O-ring is seated properly before reassembling the tap. Turn the water supply back on and test the tap to ensure the leak is fixed.

Avoid stretching the O-ring excessively during installation, as this can cause it to not seal properly. Additionally, ensure the tap components are clean and free from debris before reassembling. If the leak persists after replacing the O-ring, there might be other underlying issues that need addressing.

4. Fixing a Cartridge Tap

Cartridge taps are commonly found in modern homes and are characterised by their smooth, consistent operation. They use a movable cartridge rather than a rubber washer to control water flow and temperature. Identifying a cartridge tap is essential before attempting any repairs.

Start by turning off the main water supply to the tap. Remove the tap handle and cover plate to expose the cartridge. Once the handle is removed, you’ll see the cartridge. Use pliers to pull out the old cartridge and replace it with a new one, ensuring it’s the correct type for your tap. Reassemble the tap and turn the water supply back on to test for leaks.

Before replacing the cartridge, it’s important to ensure you have the correct replacement. Cartridges vary by brand and model, so take the old cartridge with you when purchasing a new one to match it accurately. If the tap continues to leak after replacement, there may be an issue with the tap housing or other components.

5. Using Plumber’s Tape

Plumber’s tape, also known as Teflon tape, is useful for sealing threaded connections and preventing leaky taps. It is particularly effective for minor leaks around the tap skirt and valve seating. Knowing when to use plumber’s tape can save you from more complicated repairs.

First, turn off the water supply to the tap. Disassemble the tap to expose the threaded areas where leaks are occurring. Clean the threads to remove any mineral buildup or old tape. Wrap the plumber’s tape around the threads in a clockwise direction, ensuring it is snug and covers the threads completely for a watertight seal. Reassemble the tap and turn the water supply back on to check for leaks.

When applying the plumber’s tape, make sure to wrap it tightly and evenly to avoid any gaps. Using too much tape can cause it to bunch up and prevent a proper seal. If the leak persists after applying the plumber’s tape, it may indicate a need for more extensive repairs or replacement of the tap components.

If All Else Fails, Call a Professional

Fixing a leaking tap can be a straightforward task if you know the right techniques. By tightening the tap, replacing the washer or O-ring, fixing a cartridge tap, or using a plumber’s tape, you can address most common leaks without needing professional help. These methods not only save water but also reduce your utility bills.

Addressing leaks promptly is crucial for water conservation. Regular maintenance and early repairs can prevent minor issues from becoming major problems. If these methods do not resolve the issue, it may be time to consult a professional plumber for further assistance.
