When it comes to household annoyances, a dripping tap is often at the top of the list. Not only does the constant sound of water droplets hitting the sink become grating over time, but it can also signify underlying plumbing issues that might not be immediately obvious. In this blog post, we'll explore why taps drip, how to diagnose and fix common problems yourself, and when it's time to call in a professional.
Understanding Why Taps Drip
A dripping tap can be caused by several issues, mostly stemming from wear and tear of the tap's internal components. The most common culprits are worn-out washer or O-rings, a corroded valve seat, or improper installation of the tap components. Over time, these parts can degrade or become damaged due to constant usage or mineral buildup, leading to that annoying drip.
Spotting the Problem
To effectively fix a dripping tap, you first need to identify what type of tap you have. The most common types in the UK are compression taps, which require you to tighten a screw to close the water flow, and mixer taps, which typically use a ceramic disc or ball valve. Knowing your tap type will guide your repair approach.
Tools You Might Need
Before attempting any repair, ensure you have the right tools on hand. For most tap repairs, you will need:
- Adjustable spanner
- Screwdriver set
- Replacement washers or O-rings
- Pliers
Turning Off the Water Supply
Always start any plumbing repair by turning off the water supply to the tap. This can usually be done via the isolation valve located under the sink. If there isn’t one, you might need to shut off the main water supply to your home temporarily.
Disassembling the Tap
Carefully remove the tap handle. This typically involves removing a screw, which might be hidden under a decorative cap at the top of the handle. Once the handle is off, use your spanner to loosen and remove the tap’s headgear. Here you will find the washer or O-ring that likely needs replacing.
Replacing the Washer or O-Ring
With the headgear off, inspect the washer or O-ring. If they look worn or broken, replace them with new ones that match in size and shape. It’s a good idea to take the old parts to a hardware store to ensure you get the correct replacements.
Reassembly and Checking for Leaks
Once the new washer or O-ring is in place, reassemble the tap in the reverse order you took it apart. Turn the water supply back on and check for leaks. If the tap still drips, there might be an issue with the valve seat or more complex components inside the tap.
When to Call a Professional
If replacing the washer or O-ring doesn’t fix the drip, or if the task of disassembling the tap seems daunting, it’s wise to call a professional plumber. They can diagnose and repair issues that might not be apparent to the untrained eye.
Long-term Prevention
To prevent taps from dripping in the future, consider the following:
- Regularly clean your taps and remove any limescale or mineral build-up, which can damage parts over time.
- Handle taps gently; over-tightening can wear out components quicker.
- Consider installing a water softener if you live in a hard water area to reduce mineral buildup in your plumbing systems.
Conclusion
Tackling a dripping tap can be a satisfying DIY project that saves water and prevents larger plumbing problems down the line. However, remember that it's important to approach this task with the right tools and knowledge. If at any point you feel out of your depth, calling a professional plumber is a smart decision. Remember, regular maintenance can prevent many common tap issues from developing, keeping your taps functional and quiet for years to come.
