DIY Leak Testing & Water Meter Test Guidance

Suspect a Leak? Here’s How to Check It Yourself Before You Call a Pro

 

If your water bill’s unusually high, you’re hearing dripping sounds, or noticing damp spots with no clear cause — there’s a good chance you’ve got a hidden leak.

Before you book a specialist, you can run a few simple checks at home. At Local Leak Detection Specialist, we want to help you understand your leak risk early, and if needed, we’re ready to step in with non-invasive detection equipment to find exactly where it’s coming from.

Step-by-Step Guide – How to Perform a Water Meter Leak Test

What you’ll need:

  • Access to your external water meter
  • A notepad or phone to record numbers
  • 30–60 minutes where no water will be used

Instructions:

  1. Turn off all taps, appliances, and irrigation systems inside and outside. Make sure the toilet isn’t filling and no one is using water.
  2. Locate your water meter – usually in a box near the front boundary.
  3. Take an initial meter reading – write down all the numbers, especially the small red or black dials that track litres.
  4. Wait at least 30 minutes to 1 hour, without using any water.
  5. Take a second meter reading.
    • If the numbers have changed, you likely have a leak.
    • If the dials have remained exactly the same, you’re probably in the clear.

For faster confirmation, check if your meter’s leak indicator wheel (a small red or black triangle) is spinning even when all water is off — that usually indicates water flow.

What If the Meter Test Confirms a Leak?

If the meter is moving, but you don’t see any obvious signs of a leak:

  • The leak may be underground, in your service line, or inside walls, floors, or ceilings
  • It could be hot water-related, with moisture evaporating before visible signs appear
  • You may have a toilet leak — especially common in dual-flush cisterns
  • The issue might involve irrigation systems, concealed reticulation lines, or outdoor taps

This is when professional, non-invasive leak detection makes all the difference.

Other DIY Leak Checks You Can Try at Home

Toilet Leak Test

  • Add a few drops of food colouring into the toilet cistern.
  • Wait 10–15 minutes (without flushing).
  • If the colour appears in the bowl, you have a silent toilet leak.

Shower & Bathroom Leak Signs

  • Check if walls or cabinetry near the shower are damp or swelling
  • Smell for musty odours or spot mould near tiled areas
  • Look for cracked or loose grout in showers or splashbacks

Tap & Fixture Check

  • Inspect beneath vanities, sinks, and kitchen cabinetry
  • Open cupboards and check for water stains or warped shelves
  • Ensure outdoor taps aren’t slowly dripping (especially if connected to hoses)
