A sudden high water bill is often the first sign that a hidden leak is active. In this Qormi case, the owner had received a Water Services Corporation alert about unusually high consumption and needed to know whether water was escaping somewhere inside the property.
This is the type of situation where a simple visual check is usually not enough. A hidden leak can keep the meter moving even when no taps are open, and the damage may not be obvious at first.
First check: understand the pipe layout
The homeowner was able to explain the pipe routes and show the likely service areas. That helped the inspection start with a clearer plan instead of opening walls or tiles at random.
When you are dealing with a high bill, useful first evidence includes:
- whether there is a WSC notice or high bill,
- whether the water meter keeps moving when all taps and appliances are off,
- where any damp areas, stains or wet grout appear,
- notes about toilets, tanks or valves that may be refilling.
For this type of enquiry, see our high water bill leak detection Malta guide.
Thermal and acoustic checks
Thermal imaging was used to look for temperature patterns that could suggest dampness or water movement. A damp area on a wall gave a useful clue, but thermal imaging alone does not prove the exact source of a leak.
Acoustic listening was then used to check for leak noise. This helped narrow the suspected area further and pointed the investigation toward the kitchen and nearby service route.
If the concern is a pressurised pipe leak, acoustic evidence can be particularly useful. More detail is available on our Gutermann acoustic leak detection Malta page.
Likely source found near the toilet angle valve
Further inspection identified the leak near the angle valve next to the toilet. Small valves and fittings can create large water-consumption problems because they may leak continuously while remaining partly hidden from view.
The owner was given practical repair recommendations based on the inspection findings.
What this case shows
A high water bill should not be ignored, especially when the meter moves while no water is being used. The sooner the evidence is checked, the easier it is to limit damage and avoid unnecessary opening works.
