A leaky pipe might seem like a minor issue, and we all encounter dripping taps from time to time. It’s tempting to ignore them or wonder, ‘Can I fix a leaking tap myself?’ But even the smallest leaks can lead to serious plumbing problems down the line.
Common Causes of Leaking Taps and How to Identify Them
Worn-Out Washers
One of the most frequent answers to ‘what causes a faucet to leak?’ is a worn-out washer. If your tap has started to drip even when it’s turned off, it’s often because the washer has started to deteriorate. Washers are a key part of a tap that create a tight seal, but they wear out over time due to how often we use our taps. A dripping tap can waste 24,000 litres of water a year, causing a leak that will add to your water bill. A new washer is often an easy fix; however, if the problem keeps recurring, we recommend you hire a professional plumbing service.
Damaged O-Ring
A damaged O-Ring could be the culprit if you see water pooling around the handle of your tap. This small ring helps seal the handle, but like washers, common wear and tear can cause it to crack or loosen. Over time, even minor leaks can become a big problem. If replacing the O-Ring does not resolve the leak, it may be a sign of a larger issue needing a local plumber’s help.
Corroded Valve Seat
Over time, mineral deposits can corrode the valve seat – the part connecting the tap to the spout – causing leaks around the base. If you have noticed water starting to pool around the spout of your tap, corrosion is likely a cause. Valve Seat damage is common in homes with hard water which speeds up mineral build up. While you can resurface a valve seat, severe corrosion may require a full replacement. If left unaddressed, a leaky valve seat can even increase the risk of a burst pipe, making timely repairs essential.
Loose Parts
Loose parts within your tap can cause leaks near the handle. If you notice your tap feels wobbly, it could be due to parts inside of the tap becoming loose, allowing water to leak. Tightening these parts may solve the issue, but persistent dripping may suggest deeper wear inside the tap.
Old or Poor-Quality Fixtures
Older taps or low-quality fixtures are more prone to leaks, rust, and mineral deposits, especially in homes with hard water. You might notice rust spots, mineral buildup, or persistent leaking. Upgrading to higher-quality, corrosion-resistant taps is a solid solution for long-term peace of mind.
How to fix a leaking tap at home
Shut off the water supply
If the leak is coming from the spindle or faucet, turn off the water supply to stop the flow. If the leak is from the body of the tap, you might need to take the tap apart for further inspection.
Check for blocked drains
If there are no obvious signs of leaks, check for any clogs in the drain. Use a plunger or snake to clear out any blockages. If the clog persists, it’s best to call in a professional plumber.
Replace the tap spindle
If the tap is leaking from the spindle, it likely needs replacing. Remove the old spindle and install a new one, ensuring that all screws are tightened properly for smooth operation.
Repair or replace the water supply line
A leak from the body of the tap might indicate a broken water supply line. In this case, you’ll need to either repair or replace the line. Always use a licensed plumber for water line replacements to avoid potential damage.
Fix the leaky faucet
For leaks coming from the faucet, check for a worn-out washer or gasket. Replacing these components should resolve the leak. Ensure that new parts are installed correctly and tighten all screws.
