Flexi pipes, also known as flexible hoses, are commonly used in modern plumbing to connect taps to the main water supply, especially in confined spaces like under kitchen sinks or bathroom basins. They are valued for their adaptability and ease of installation. However, these pipes can sometimes burst, leading to significant water leakage and potential damage to your property. In this blog post, we'll explore the reasons behind flexi pipe bursts, how to identify and repair them, and steps to prevent future issues.
Why Do Flexi Pipes Burst?
Flexi pipes burst primarily due to three reasons: age, poor installation, and water pressure issues.
1. Age and Material Fatigue: Over time, the materials in flexi pipes, typically rubber lined with braided stainless steel, can degrade and lose their elasticity, especially if exposed to continuous high temperatures and pressures. This leads to cracks or splits in the pipe.
2. Poor Installation: If flexi pipes are not installed correctly, they can be under undue stress. Tight bends, over-stretching, or compression can weaken the pipe structure.
3. High Water Pressure and Surges: Excessively high water pressure or sudden surges, often caused by faulty pressure regulators or when other large appliances start and stop, can lead to a burst pipe.
How to Spot a Burst Flexi Pipe
Recognising a burst flexi pipe early can save a lot of hassle and potential damage. Here’s what to watch out for:
- Water pooling under the sink: If you notice unexplained water under your sink, it’s a probable sign of a leak.
- Dampness or water stains in adjacent cabinetry: Water escaping from a burst flexi pipe often soaks into nearby wood or walls.
- Reduced Water Pressure: A burst pipe can reduce the pressure in your tap or shower, as some of the water diverts through the split in the hose.
DIY Repair Steps
If you discover a burst flexi pipe and feel confident in tackling it yourself, here’s what you can do:
1. Turn Off the Water Supply: Always start by turning off the main water supply to prevent further flooding and damage.
2. Relieve Pressure: Open the taps connected to the burst pipe to drain any remaining water in the system.
3. Remove the Damaged Flexi Pipe: Use a wrench to loosen the nuts holding the flexi pipe at both ends. Be careful not to twist the pipe fittings on the tap or the supply pipe as this could cause further damage.
4. Measure and Purchase a Replacement: Take the old pipe to your local hardware store to find an exact match in length and diameter.
5. Install the New Pipe: Fit the new pipe, ensuring not to over-tighten the connections which could strip the threads or damage the washers, leading to leaks.
When to Call a Professional
If at any step the repair feels out of your depth, or if after replacing the flexi pipe you still notice leakage or dampness, it’s wise to call in a professional plumber. A plumber can properly assess the situation, ensure all fittings are correct and secure, and check for other potential issues in your plumbing system.
Preventing Future Bursts
To help avoid future bursts in flexi pipes:
- Regular Checks: Make it a habit to periodically inspect the space under sinks for signs of wear or leaks in the flexi pipes.
- Pressure Regulator: Consider installing a pressure regulator if your home experiences high or fluctuating water pressure.
- Quality Materials: Invest in high-quality flexi pipes with robust internal lining and adequate warranty coverage.
Conclusion
A burst flexi pipe under your sink can be a serious concern, but with prompt action, it's a manageable one. Understanding what to look out for and how to address the issue can save you from more significant problems down the road. Regular maintenance and appropriate installation can extend the life of your flexi pipes. However, remember that when in doubt, or when the situation feels beyond your skill set, seeking professional help is the most reliable choice to ensure your home’s plumbing integrity.
