The Hidden Enemy: When to Call for Leak Detection

The Hidden Enemy: 4 Signs You Have a Secret Leak (And Why Leak Detection is Essential)

At Earlsfield Plumbers & Leak Detectors, we often hear from clients who have been battling a persistent problem without knowing the source. The truth is, many of the most damaging leaks are completely invisible, happening silently behind walls, under floors, or beneath foundations.

These hidden enemies can cause structural damage, black mould, and skyrocketing utility bills. So, how do you know if you have a secret leak?

Here are four clear signs that it’s time to call in the trenchless leak detection experts at Orsco:

1. The Water Meter Test (The Undeniable Proof)

This is the most reliable DIY test for any leak, big or small:

  • Action: Turn off every water-using appliance in your home (taps, washing machine, dishwasher, toilets).

  • Check: Look at your water meter. If the dial or digital reading is still moving, you have water flowing somewhere – and that somewhere is a leak.

2. Sudden, Unexplained High Water Bills

Have your water charges jumped dramatically this month, but your usage hasn’t changed? This is a classic indicator of a constant leak, often hidden beneath your slab or yard.

  • Warning Sign: A bill increase that cannot be explained by extra laundry, garden watering, or visiting guests. A toilet running constantly can also be a culprit, but significant jumps often point to bigger, pipe-related leaks.

3. Visible Damage, But No Obvious Source

If you see these issues, the leak is likely localised and active:

  • Paint or Wallpaper Changes: Peeling, bubbling, or discolouration on walls or ceilings.

  • Mould or Mildew: Any sudden appearance of mould, especially in areas not prone to normal bathroom humidity (like ceilings, baseboards, or drywall).

  • Dampness: Soft spots on drywall or persistent dampness on flooring near walls.

4. The Sound of Running Water

Your home should be silent when all appliances are off. If you hear the faint, continuous sound of water running, dripping, or trickling – especially late at night – this is a high-priority warning sign.

  • Tip: Listen carefully near bathroom walls, where supply lines are common, or near your main incoming water line.
