When it comes to maintaining a home, dealing with a leaking outdoor tap can be a surprisingly common and frustrating issue. Whether it’s dripping water causing a nuisance or the concern about wasting water and increased utility bills, understanding why your tap is leaking and knowing what to do about it is essential. This blog post will provide you with a detailed guide on diagnosing, addressing, and preventing leaks in your outdoor tap.
What Causes an Outdoor Tap to Leak?
Leaking outdoor taps can stem from various issues, but the most frequent cause is the deterioration of the washer or O-ring inside the tap. These components are critical for forming a water-tight seal. Over time, exposure to the elements and the constant pressure of water can wear them down, causing water to escape through the handle.
Another common issue is damage or corrosion to the tap’s valve seat, where the washer seals against. If this becomes uneven or corroded, it will not provide a smooth surface for the washer, allowing water to drip through.
Identifying the Leak
The first step in tackling a leaky outdoor tap is to correctly identify where the leak is coming from. If water appears around the handle when the tap is turned on, it is likely that the issue lies with the internal washer or O-ring. Checking for moisture around the spout or any parts of the tap when it is off can also point towards other issues like a faulty valve seat.
Turning Off the Water Supply
Before attempting any repairs, it’s important to shut off the water supply to the tap. This is usually done by turning off an isolation valve along the water line specifically for that tap or by shutting off your home’s main water supply if an isolation valve is not present.
Replacing the Washer or O-Ring
1. Once the water is off, open the tap completely to drain any residual water.
2. Use an adjustable spanner to carefully unscrew the nut that secures the tap handle.
3. Remove the handle and any cover to expose the stem. You will see the O-ring or washer at the end of this stem.
4. Remove the old washer or O-ring and replace it with a new one of the same size and type.
5. Reassemble the tap and turn back on the water to test if the leak has been fixed.
Inspecting and Repairing the Valve Seat
If replacing the washer or O-ring doesn’t solve the problem, the next step is to check the valve seat:
1. Dismantle the tap again as per the steps above.
2. Use a flashlight to inspect the valve seat inside the tap. Look for any signs of damage or corrosion.
3. If the seat is damaged, it may be possible to re-smooth it using a valve seat grinder. However, this is a more intricate job and might require professional help.
Calling a Professional
While many minor leaks can be handled through DIY repairs, there are situations where calling a professional plumber is advisable:
- If the tap continues to leak despite changing the washer and inspecting the valve seat.
- If there is significant damage to the tap or its connections.
- If you’re not confident in performing the repairs yourself.
Preventing Future Leaks
To prevent future leaks, consider the following tips:
- Regularly check and replace the washers and O-rings every couple of years, especially if they begin to show signs of wear.
- During colder months, ensure your outdoor taps are adequately insulated to prevent freezing and cracking.
- Periodically turn the tap on and off to ensure it’s not seizing up from lack of use, which can also lead to leaks.
Conclusion
Addressing a leaky outdoor tap is an essential skill for maintaining a home’s plumbing system. With the right tools and some patience, most homeowners can handle replacing a worn washer or O-ring. However, don’t hesitate to call a professional if the job becomes too complex or if the leak persists after your initial fix. By taking proactive steps to check and maintain your outdoor taps, you can ensure they remain in good working condition for years to come.
