What Causes Your Tap to Drip and How to Fix It

There’s nothing quite like the persistent plink-plink of a dripping tap to remind you of minor household annoyances that can surprisingly disrupt the peaceful ambiance of your home. Not only is it an irritation, but it can also signal a waste of water and potentially increase your water bill over time. Understanding what leads to this common issue and knowing how to address it effectively can save you not only on costs but also prevent potential water damage.

Dripping Tap: Understanding the Common Culprits

A dripping tap can be the result of various factors. It might seem like a simple annoyance, but behind that drip could be several issues ranging from worn out washers, improper tap installation, high water pressure, or even corroded valve seats. The cause primarily determines the approach to fix it, making it crucial to properly diagnose the root problem before attempting repairs.

Recognise the Type of Tap

Before diving into repair methods, identify what type of tap you have. The two main types are compression taps, which have two handles for hot and cold water, and mixer taps, which mix the water internally and release it through a single spout. This knowledge will guide specific repair steps, as each type has its involved mechanism.

Check the Washer and O-Ring

Many dripping issues stem from a worn out washer or O-ring. These are located inside the tap and are crucial for forming a tight seal to stop water from leaking. Over time and through constant use, these washers can degrade or get misshaped. Turning off your water supply, dismantling the tap, and assessing the washer and O-ring for any wear and tear is the first step towards solving the issue.

Look for Corrosion in the Valve Seat

The valve seat in the tap can also be a common reason for leaks. The valve seat is where the tap and spout meet. Water sediments can accumulate here, leading to corrosion and, subsequently, water leakage. Removing the valve seat and checking for any signs of corruption should be on your checklist when diagnosing your dripping tap issue.

Water Pressure Issues

If your tap only drips at certain times of the day or during specific operations, it might be a water pressure issue. Fluctuations in water pressure can cause the water to find a way through weakened parts of your tap. Consulting with a professional plumber can help you determine if water pressure is the root cause and advise on ways to stabilise pressure throughout your plumbing system.

How to Solve the Dripping Tap

Once you've identified the cause, you can either choose to DIY the repair or call in a professional. For simple washer replacements:

1. Turn off your main water supply to avoid a mini flood.

2. Disassemble the tap handles using appropriate tools like wrenches or screwdrivers.

3. Replace the old washer with a new one that matches in size and composition.

4. Reassemble the tap and turn on the water supply to check if the dripping has ceased.

When to Call a Professional

While many tap issues can be resolved with a DIY approach, certain conditions warrant professional intervention. If the dripping persists even after replacing washers and O-rings, or if there’s significant corrosion, it might be best to call in a licensed plumber. Attempting to fix complex plumbing without proper knowledge can lead to more significant issues or potential water damage.

Preventing Future Drips

Preventative maintenance can go a long way in avoiding recurring tap leaks. Regularly checking and replacing washers and O-rings before they wear out completely is one preventive measure. Also, managing the sediment buildup through periodic cleaning of the valve seat and being mindful of your home’s water pressure can help maintain your taps in good working condition.

Conclusion

Dealing with a dripping tap is more than just an annoyance; it can be a learning opportunity in the basics of home plumbing maintenance. By understanding common causes and exploring both DIY and professional repair options, you can prolong the lifespan of your taps. Remember, prevention is always better than cure, so keep an eye on the small changes and address them before they evolve into major issues, ensuring peace and quiet—and a dry sink!
