Before we start: what we know about Al Snabl

The centre of Al Snabl is at 21.3891, 39.2729, about 20 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 1.2 km from the centre of Al Snabl (OpenStreetMap).

The centre of Al Snabl sits about 35 m above sea level (SRTM open elevation data). Al Snabl is about 8.8 km from the sea coast (OpenStreetMap).

In Al Snabl, the first thing we check for hidden water leaks is the location itself, because the setting shapes where water tends to go. The centre of Al Snabl sits about 35 m above sea level, and the area lies roughly 8.8 km from the sea coast, so pipework and ground conditions here are not the same as those near the shoreline. The nearest wadi channel is about 1.2 km from the centre of Al Snabl, which means rainwater runoff and ground moisture can behave differently from one street to the next. Our technicians therefore start by reviewing the building's position in the wider area, then narrow the search to the pipes, tanks and joints most likely to be affected.

Some points can only be settled on site. The exact route of concealed pipes, the condition of joints behind finished walls, and whether a leak is coming from the supply side or the drainage side all depend on what is physically found during the visit. The technician will confirm the reading from any test, decide whether a pressure or acoustic check is needed, and judge whether a tank needs attention. Where a water tank is involved, the internal coating cost is a fact to keep in mind: tank internal coating is priced at SAR 25–65 per m², so the scope of any coating work is set only after the tank has been measured and inspected in person.

To help the technician, residents should prepare a short note before the visit. Record when damp patches, unexplained rises in the water meter, or soft flooring were first noticed, and mention whether the building has a rooftop or ground-level tank. Share the building's approximate elevation and its distance from any wadi or open drainage line nearby, as these details match the local facts above. Clear access to the bathroom walls, kitchen cabinets, and tank area will also save time. With this information ready, the visit can focus on finding the leak rather than gathering background details.

For a whole building, a survey of the shared systems comes before unit-by-unit work.

When do you need hidden water leak detection?

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 meter keeps turning with every tap closed

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.

Tools we use in Al Snabl

From the first visit to the report

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.
