Before we start: what we know about Am Al Slm

The centre of Am Al Slm is at 21.4523, 39.3562, about 21.5 km from the centre of Jeddah, with an approximate radius of 1.2 km. The service-area circle on the map below is drawn from this point. The nearest wadi channel is about 1.8 km from the centre of Am Al Slm (OpenStreetMap).

The centre of Am Al Slm sits about 145 m above sea level (SRTM open elevation data). Am Al Slm is about 17.7 km from the sea coast (OpenStreetMap).

Hidden water leaks are the most common problem in Am Al Slm homes, and they usually show up as a slow rise in the water bill, damp patches on walls or floors, or a faint musty smell in ground-floor rooms. Because the leak is out of sight, residents often notice it only after the damage has spread. Common sources include pipes running under concrete slabs, joints in the rooftop water tank, and older supply lines that have worn over time. A detection visit typically checks the meter for movement while all taps are closed, then listens for hidden flow and uses moisture readings to narrow down the location before any opening work begins.

The local setting changes how this work is approached. The centre of Am Al Slm sits at 21.4523, 39.3562, about 21.5 km from the centre of Jeddah, and the approximate radius of the area is 1.2 km, so many homes are spread across a compact, self-contained district that is still a drive from the city core. The area lies about 145 m above sea level and roughly 17.7 km from the coast, which means the team should expect a dry, inland environment where heat can dry out surfaces quickly and make some damp signs easy to miss. The nearest wadi channel is about 1.8 km from the centre, so properties near low ground may face more groundwater or flood-related moisture, and technicians should check for that before attributing every stain to a pipe.

Before booking the visit, ask the provider to explain how they will locate the leak and what method they will use, and whether they will confirm the result with a meter test before any wall or floor is opened. Ask which parts of the system they cover, such as the rooftop tank, the main line, or only the fixtures inside the home. If repairs may be needed, ask how the tank internal coating is priced, which is SAR 25–65 per m², so you can compare the scope of work against the area to be treated. Finally, ask who will repair any opened surfaces afterwards, so the final cost is clear before work starts.

When do you need hidden water leak detection?

If you notice one of these signs in Am Al Slm, it is a good moment to talk to the team:

• 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 hot line that expands and contracts with use — we check this before anything else.
• A common cause: a cracked pipe under floor tiles.
• A corroded joint inside a wall.

Tools and methods, and when we use them

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.
