Al Hrm sits at the coordinates 21.4241, 39.8259, roughly 5.1 km from the centre of Makkah, and its built area spans an approximate radius of 1.2 km. That footprint is compact enough that a technician can reach most properties in a single visit from a central base, but it is also dense enough that pipe routes often run close to neighbouring buildings. For a hidden water leak check, this means the survey begins with a clear map of the building's supply lines, shared risers and any old branches that may have been added over the years, rather than a quick walk-around.

The centre of Al Hrm lies about 304 m above sea level, according to SRTM open elevation data. Elevation matters for water pressure: at this height, rooftop tanks and gravity-fed lines behave differently from ground-level supply, and a pressure change can reveal a leak that was silent before. Technicians therefore note static and working pressure at several points during the check, and they compare readings between floors. A drop that appears only under demand usually points to a fault further along the line, which is why the test is run both with and without taps in use.

Practical planning follows from these facts. Because the area is compact and elevated, owners should keep tank access clear and tell the technician where the storage tanks, pump room and main isolation valve are located before the visit. If a tank shows signs of a leak or seepage, the internal lining may need repair. Interior coating for tanks is commonly priced per square metre, at SAR 25–65 per m², so the surface measurement taken during the survey gives the owner a realistic basis for comparing options. Owners in Al Hrm avoid several common mistakes: they wait for a damp wall before calling anyone, they assume a higher water bill is only a tariff change, they cover or paint over suspect patches before inspection, and they hire work without asking for the measured area in writing.

Signs worth paying attention to

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

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

The most common causes

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

How we choose the tool in Al Hrm

How the work is done, step by step

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.

What we advise against

• Breaking tiles at random before the line is identified
• Repainting the stain while the moisture keeps coming back
