A dripping tap might seem like a minor nuisance, but it can quietly cause big problems over time. Even a slow drip can waste thousands of litres of water each year, push up your water bills, and lead to wear and tear in your plumbing. Many people ignore a dripping tap, thinking it’s harmless, but understanding the cause and acting quickly can save both money and stress.
In this article, we will explore why taps drip, the most common causes, and simple ways to fix them. We’ll also discuss when it’s best to call a professional and why fixing even a small drip is better for both your home and the environment.
Why You Shouldn’t Ignore a Dripping Tap
A small drip might not seem important, but it can add up over time. For example, a single tap dripping once every second can waste more than 3,000 litres of water in a year. That’s not only bad for the environment, it can also have a noticeable impact on your water bills.
Beyond the cost, a dripping tap can gradually damage your plumbing. Continuous dripping can wear down washers, spouts, and fittings, potentially leading to more serious leaks or corrosion. And let’s not forget the irritation factor—the constant sound of dripping water can be especially annoying at night.
Fortunately, most dripping taps can be fixed relatively easily if you know what to look for.
Common Causes of a Dripping Tap
There are several reasons why taps may start to drip, and most of them are straightforward to fix.
One of the most frequent causes is a worn washer. Washers are small rubber or silicone rings that sit inside the tap and help seal the water flow. Over time, they can become stiff, cracked, or worn out, which prevents the tap from closing properly and causes drips.
Another common culprit is a damaged O-ring. O-rings are small rubber rings located inside the tap handle, creating a watertight seal. If they become worn or loose, water may leak around the handle or even inside the tap.
Corrosion or sediment build-up on the valve seat is another common problem. The valve seat connects the tap body to the spout, and hard water can cause it to corrode over time. When the seal isn’t tight, water can escape, resulting in a persistent drip.
Sometimes, the cause is simpler: loose parts inside the tap can allow water to leak. In modern mixer taps, a worn cartridge can also lead to dripping. Lastly, excessive water pressure in your home can force water through the tap even when it’s turned off.
How to Fix a Dripping Tap
Most dripping taps can be repaired at home if you take the right precautions. The first step is always to turn off the water supply to avoid flooding.
Replacing a worn washer is usually the simplest solution. Remove the tap handle, take out the old washer, and fit a new one of the correct size. Similarly, if the leak is around the handle, replacing the O-ring will often solve the problem.
If corrosion or sediment is causing the drip, cleaning or replacing the valve seat can restore a proper seal. For minor leaks caused by loose parts, tightening screws or fittings may be enough. In mixer taps, replacing a worn cartridge is often the most effective fix.
If your home has high water pressure, installing a pressure-reducing valve can prevent taps from dripping and protect your plumbing system.
Preventing Future Tap Drips
Preventing taps from dripping is easier than fixing them after the fact. Regular maintenance can save both water and money. Check your taps periodically for wear and tear, and avoid over-tightening them, as this can damage washers and O-rings.
In areas with hard water, sediment can build up inside taps. Using filters or tap covers can help prevent this problem and extend the life of your fittings. Maintaining proper water pressure throughout your home also helps reduce leaks and protects your plumbing.
Even small steps, like regular inspection and gentle use, can make a big difference over time.
When to Call a Professional
While many tap issues can be solved at home, some situations require professional help. If the drip persists after replacing washers and O-rings, or if there is corrosion or damage inside the tap, it’s time to call an expert. Multiple taps dripping at once or uncertainty about the repair process are also good reasons to seek professional assistance.

Benefits of Fixing a Dripping Tap
Fixing a dripping tap is not just about saving money—it also helps the environment. Every drop of water counts, and reducing wastage helps conserve valuable resources.
By addressing drips promptly, you also reduce the energy required to treat and heat water, which lowers your household’s carbon footprint. At the same time, stopping leaks helps prevent further damage to your plumbing, saving potential repair costs in the future.
Even a small tap repair can have a noticeable impact over time, both financially and environmentally.
Conclusion
A dripping tap may seem minor, but it can waste thousands of litres of water, increase bills, and damage your plumbing if left unchecked. Most drips are caused by simple issues, such as worn washers, damaged O-rings, or worn cartridges. Many of these problems can be fixed with a few tools and a little attention.
Regular maintenance, careful use, and timely repairs can prevent most tap drips. When in doubt, or if the problem is persistent or complex, it’s wise to call a professional.
