It's a common annoyance: you go to wash your hands, water your plants, or start the washing up, and notice water pooling around the base of your tap. Not only is it inconvenient, but over time, it can lead to water damage, mold growth, and an increase in your water bill. In this post, I'll walk you through why your tap might be leaking at the base, how you can fix this issue yourself, and when it might be time to call in a professional.
Understanding Why Taps Leak at the Base
Leakage at the base of a tap usually stems from a problem with the internal components of the tap. These components can wear out or become damaged over time due to various factors, including water pressure, mineral buildup, and general wear and tear. Here are some common causes:
1. Worn O-Ring
The O-ring is a small rubber ring located at the base of the tap's spindle. Its main job is to prevent water from leaking out around the handle when the tap is turned on. Over time, O-rings can become brittle or loose, causing water to escape around the base of the tap.
2. Corroded Valve Seat
The valve seat is the connection between the tap and the spout. Water sediments can build up here, causing corrosion and consequent leakage.
3. Improper Installation
If your tap wasn’t installed correctly, or if it’s become loose over time, it can start to leak at the base. This misalignment can cause undue stress on different parts of the tap, leading to leaks.
Diagnosing the Leak
To find the true cause of the leakage, you need to take a closer look at your tap. Here’s how you can get started:
- First, ensure the water supply to the tap is turned off. This is typically done via the isolation valves under the sink.
- Open the tap to release any residual water and pressure in the pipes.
- Use an appropriate tool, such as a wrench or a screwdriver, to carefully disassemble the tap. Keep all parts, including any screws or washers, in a safe place so you don’t lose them.
Fixing the Leak
Depending on the diagnosed problem, here are some ways you can fix a leaky tap:
1. Replacing the O-Ring
- Remove the old O-ring and any mineral deposits on the spindle.
- Apply some plumber's grease on the new O-ring and roll it into place.
- Reassemble the tap and check for leaks.
2. Cleaning or Replacing the Valve Seat
- Use a valve seat wrench to remove the valve seat.
- Inspect it for wear or corrosion. If it’s damaged, replace it; otherwise, clean it thoroughly.
- Screw the valve seat back and reassemble the tap.
3. Tightening or Realigning the Tap
- If the tap is loose, use a basin wrench to tighten the nuts under the sink.
- Check the alignment of the tap to ensure it’s positioned correctly and not subjecting parts to unnecessary stress.
When to Call a Professional
While many tap leaks can be fixed at home with a few tools and a bit of patience, there are times when it's advisable to call a professional plumber:
- If the leak persists after you’ve made adjustments, there might be a deeper, more complex issue.
- If there is significant corrosion or damage to the tap parts, a plumber can provide a more thorough examination and replacement if necessary.
- If you’re not comfortable taking apart and reassembling the tap, it’s better to call in a professional to avoid causing further damage.
Prevention Tips
Maintaining your taps can prevent issues from cropping up in the first place. Here are a few tips:
- Regularly clean your taps and remove any limescale or mineral build-up.
- Occasionally check under the sink to ensure all connections are tight and there is no moisture that could indicate a small leak.
- During routine home maintenance, include checking and replacing O-rings and washers if they show signs of wear.
Conclusion
Dealing with a leaky tap might seem daunting, but understanding why leaks occur at the base and knowing how to fix them can save you a lot of time and money in the long run. Remember, while DIY fixes are a great first line of defense, don't hesitate to call in a professional if the problem persists or you're unsure of your DIY skills. Regular maintenance is key to keeping your plumbing in top shape and preventing future leaks.
