At 911 Drain & Plumbing, we respond to water leak emergencies every week. Some leaks are easy to spot, but many are hidden behind walls, under floors, or even underground. Knowing the signs can save you thousands in damage and repairs.
Common Causes of Hidden Leaks
1. Aging pipes
Homes built decades ago in Pretoria East often have older plumbing that can corrode or crack, leading to slow leaks.
2. High water pressure
Too much pressure in your pipes can stress joints and fittings, causing small leaks that grow over time.
3. Poor installations
Improperly fitted taps, valves, or geysers sometimes start leaking after a few months or years, particularly in homes that have had renovations.
4. Underground or outdoor leaks
Pipes running under driveways, patios, or gardens can develop leaks that are invisible until they cause sinkholes, wet patches, or unusual damp smells.
How to Spot a Leak Early
- Look for damp or discoloured patches on walls, ceilings, or floors
- Listen for hissing or dripping sounds when no water is being used
- Check your water meter overnight. If it moves while all taps are off, you likely have a hidden leak
- Notice unusual spikes in your water bill
- Smell musty odours or detect mildew in cupboards or behind appliances
Quick Home Checks
While some leaks need professional attention, these quick checks can help you identify early signs:
- Inspect exposed pipes under sinks and behind toilets
- Touch walls and floors for damp spots
- Look at the base of your geyser for drips or puddles
- Keep an eye on garden areas for unusually wet patches
Professional Leak Detection
At 911 Drain & Plumbing, we use modern leak detection tools, including thermal imaging cameras and acoustic sensors, to locate leaks without damaging your property. Last month in Menlyn, we traced a slow underground pipe leak causing damp in a living room. By detecting it early, we prevented major water damage and costly repairs.
