Hidden water leak detection in Al Bsatyn, Makkah, starts with confirming where the problem is most likely to sit before any equipment is set up. The district's centre lies at 21.4000, 39.7266, roughly 13.7 km from the centre of Makkah, and the area covers an approximate radius of 1.2 km. Because of that spread, our first check is the layout of the property relative to the neighbourhood's network, including the likely route of the supply line from the street connection to the building. The centre of Al Bsatyn sits at about 309 m above sea level, which matters for pressure readings, so the technician will note the pressure at the meter and at the highest outlet before drawing any conclusions about where the water is escaping.

What is left to the site visit is the actual search. Floors, walls, slabs and any buried pipework can only be checked in person with the right instruments, and we cannot judge the extent of damage from a description alone. The technician will decide whether the leak is in a supply line, a drainage run, a fitting or a storage tank. If a tank is involved, the internal coating is a separate matter: the cost of tank internal coating is quoted at SAR 25–65 per m², but the surface area and condition can only be measured on site, so no figure should be taken from this page as a final price.

To help the technician arrive prepared, note when the damage was first noticed, whether the water bill has risen, where damp or staining appears, and whether the sound of running water is heard when all taps are closed. Share the building's access arrangements, the location of the main stopcock, and any previous repairs. Keep the water supply on until the visit unless the technician advises otherwise, and do not dig or break finishes yourself, since this can make the search harder.

If water is flowing, close the main valve first, then call or message with photos.

Signs that call for hidden water leak detection

These are the signs most often linked to hidden water leak detection:

• The meter keeps turning with every tap closed
• A water bill higher than usual with no change in use
• A damp patch that slowly grows on a wall or ceiling
• A hissing or trickling sound in the wall after the taps are off

Causes we see in the field

• A common cause: a corroded joint inside a wall.
• A common cause: a cracked pipe under floor tiles.
• A common cause: a hot line that expands and contracts with use.

Tools and methods, and when we use them

The steps in order

1. Meter test: We stop all use and watch the meter to confirm whether water is actually being lost.
2. Line isolation: We close valves one line at a time to see which line loses pressure.
3. Acoustic listening: We follow the sound of water escaping under pressure and compare its strength between points.
4. Thermal imaging and moisture mapping: We map how far the wet area spreads behind paint and tiles.
5. Documentation: Readings, photos and the likely position go into a written report.
