6 Signs There Is A Leak In Your Plumbing

March 21, 2024

While plumbing leaks may initially appear as minor annoyances, they often indicate more serious underlying issues. Recognising the signs and understanding the consequences of these leaks are important steps in effectively tackling them. In this blog, we'll explore six signs there is a leak in your plumbing.

1. Unexpected Increase In Water Bills

An unexpected increase in your water bill is a warning sign. While it's normal for your bill to fluctuate slightly due to seasonal variations, a sudden spike could indicate leakage. It's particularly concerning if your water usage hasn't significantly changed, but your bills are soaring. This can lead to significant wastage of water.


To mitigate this, it's advisable to conduct regular checks on your plumbing fixtures. Early detection and repair of leaks can prevent the escalation of water bills and contribute to water conservation, which is an essential practice in today's environmentally conscious world.

2. Mould Or Mildew Presence

Mould thrives in damp environments and a persistent water leak presents the perfect conditions for growth. If you spot mould or mildew patches on walls, ceilings or corners that persist even after a thorough cleaning, it may be a sign of a hidden plumbing leak. Moreover, exposure to mould can cause health problems like respiratory issues and allergies.



So, a persistent mould problem is more than an aesthetic issue—it's a potential health risk. Ensuring proper ventilation in your home and seeking professional plumbing services can help prevent mould growth and safeguard your property.

3. Water Stains Or Damaged Paint Or Wallpaper

Water stains on your ceilings or walls are telltale signs of plumbing leaks. These stains may appear as discoloured spots or patches and can lead to peeling paint or wallpaper. Such damage often indicates a leak in the plumbing lines running within or above these surfaces.

Ignoring these signs can lead to more extensive damage over time, including weakened structural elements and further aesthetic degradation. Early detection and repair can save you from more significant repairs down the line.

4. Musty Odours

Our homes tend to have a unique smell—one that's typically comforting and familiar. However, a persistent musty odour could be a sign of a plumbing leak. These smells are often indicative of water lingering in places where it shouldn't be, like behind walls or underneath flooring.


Beyond the immediate discomfort, these smells can have long-term effects on your home's structure and air quality. If regular cleaning and ventilation are not effective in eliminating these odours, it may be time to suspect a leaking pipe and call a professional for help.

5. Low Water Pressure

When water doesn't flow as forcefully as it should, it might indicate a leak or blockage in your pipes that's diverting the water away from where it's supposed to go. This drop in pressure can affect various fixtures across your home, from taps to shower heads, making daily tasks more challenging.


Identifying and addressing the cause of low water pressure can help restore convenience and prevent the potential for more serious plumbing problems down the line. If you notice a sudden or gradual decrease in water pressure, it's wise to rely on plumbers to investigate further.

6. Sounds Of Running Water

If you hear the sound of running water despite all taps being tightly turned off, you may have a leak in your plumbing. It could be water escaping from a pipe, running through your walls or beneath your floors. Often, this sound is subtle and you'll need a quiet environment to hear it.


Looking for such sounds should be a regular part of your home maintenance routine. Remember, water leaks persist 24/7. Don't dismiss that faint, unexplained sound of running water; it could be an important sign of a hidden leak.
