Why Is My Tap Leaking? Let’s Find Out!

Dripping taps are a common household nuisance that can lead to wasted water, higher water bills, and even structural damage if left unaddressed.

In this blog, we’ll explore the common reasons behind a dripping tap and what you can do to fix them.

So, why is your tap leaking? Let’s find out!

1. Worn-out Washers

A worn-out washer is one of the most frequent culprits for a leaky tap. A tap washer is a small rubber seal or silicone disc that creates a watertight seal when you turn the tap off.

Over time, these rubber washers can deteriorate due to constant use, leading to leaks around the spout. Replacing the tap washer is a relatively simple DIY fix, but turning off the water supply to the tap is crucial before attempting any repair.

2. Corroded Valve Seats

The valve seat is another critical component that can cause a dripping tap. It’s the part of the tap that connects to the tap spout and controls the flow of cold or hot water from your mixer tap. If the valve seat becomes corroded or damaged, it may not form a proper seal, resulting in leaking taps.

3. Loose or Worn-out O-rings

O-rings are rubber rings that create a seal around the base of the tap handle. If these rings become loose or damaged, they can allow water to seep out. Replacing an O-ring is usually straightforward and can be done without professional help. Just remember to turn off the water supply.

4. High Water Pressure

Excessively high amounts of water can strain your taps and cause them to leak. Consider installing a pressure regulator if you notice leaks when the water is exceptionally high in pressure. This device will help maintain consistent and safe powered water throughout your home, preventing future leaks.

5. Improper Installation

Sometimes, the root cause of a leaking tap can be traced back to its initial installation. If the tap body isn’t installed correctly, it may not form a watertight seal. In such cases, it’s best to consult a professional plumber to re-install the tap correctly and prevent future leaks.

6. Worn-out Cartridges Or Ceramic Discs

Compared to traditional taps, monobloc lever taps often use cartridges or ceramic discs instead of traditional washers. These components can also wear out over time, leading to taps leaking.

Replacing a cartridge or ceramic disc may require some plumbing skills and specific tools, such as a flat-head screwdriver or adjustable spanner, so consider hiring a professional if you’re not confident in your abilities.

7. Age And Wear

Like all things, taps have a lifespan. If your tap is quite old and has seen years of use, it may be time for a replacement. Newer taps are designed with improved materials and technology, making them more efficient and less prone to leaks.

8. Cracked Pipes

Sometimes, a tap drip may not directly relate to the tap but to the pipes behind the wall. Cracked or damaged pipes can allow water to escape and manifest as a tap leak. If you suspect this is the issue, it’s crucial to have a professional plumber inspect and repair the pipes.

9. Temperature Fluctuations

Extreme temperature changes, such as freezing conditions, can cause pipes to expand and contract. This can lead to cracks and leaks in the pipes and the taps. Ensuring proper insulation and protection for your pipes during cold weather can help prevent this type of leakage.

10. DIY Repairs Gone Wrong

Sometimes, attempts at DIY tap repairs can worsen the problem. If you’ve recently tried to fix a leak, and it’s only gotten worse, it’s time to call a professional plumber to assess and rectify the situation.

Say Goodbye To Leaky Taps!

In conclusion, a leaking tap can have various causes, ranging from worn-out washers and O-rings to high water pressure and improper installation. Identifying the specific issue is the first step in resolving the problem. While some tap repairs can be tackled as DIY projects, others require the expertise of a professional plumber.

Regular maintenance and timely repairs are essential to ensure your taps remain in good working condition. Remember, promptly addressing a leak saves water and money and prevents further damage to your plumbing system.
