Before we start: what we know about Al Qyrwan

The centre of Al Qyrwan is at 24.8794, 46.5626, about 21.7 km from the centre of Riyadh, with an approximate radius of 8 km. The approximate area shown on the map is centred here. Main roads in or near Al Qyrwan: King Khalid Road, King Fahd Road, Prince Mohammed bin Saad bin Abdulaziz Road.

The nearest wadi channel is about 0.4 km from the centre of Al Qyrwan (OpenStreetMap). The centre of Al Qyrwan sits about 692 m above sea level (SRTM open elevation data).

Al Qyrwan sits at 24.8794, 46.5626, roughly 21.7 km from the centre of Riyadh, and its built-up area spans an approximate radius of 8 km. That distance matters for hidden water leak detection because it places most residential buildings on the outer edge of the city's network, where pressure and supply patterns can differ from the core. Our technicians plan each visit around the building's own plumbing layout rather than assuming the city supply behaves uniformly, which is why a survey in Al Qyrwan starts with a record of the building's age, tank position and pipe routes.

The centre of Al Qyrwan lies at about 692 m above sea level, and the nearest wadi channel runs roughly 0.4 km from that centre. Elevation affects how water is stored and pumped, so a building that relies on a rooftop or ground tank may show pressure changes that point to a leak in a supply line rather than a fixture. The wadi's proximity is practical too: seasonal runoff and loose soil near the channel can shift ground around buried pipes, so our crews check for moisture patterns in outer walls and slab edges that closer-in sites rarely show. Owners should note any damp patches that appear after rain, because these often link to ground movement rather than a simple fixture fault.

Owners in Al Qyrwan often make the same few mistakes, and our service is designed to prevent them. Many wait for a visible stain before calling anyone, when a hidden leak may have run for weeks. Others replace a tank or recoat its interior without first confirming where the water is escaping, which spends money on the wrong fix. Tank internal coating is priced at SAR 25–70 per m², so measuring the affected area before ordering work avoids paying for coating that a targeted repair would have made unnecessary. Finally, some owners ignore a rising water bill, which is often the earliest clue that a concealed line is losing water. Raising these signs early keeps a hidden leak small and the repair simple.

For a residential building, shared risers, tanks and pumps are checked as one system.

Signs that call for hidden water leak detection

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

• A damp patch that slowly grows on a wall or ceiling
• A hissing or trickling sound in the wall after the taps are off
• The meter keeps turning with every tap closed
• 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 corroded joint inside a wall — we check this before anything else.
• A cracked pipe under floor tiles.

Tools we use in Al Qyrwan

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.

Questions from Al Qyrwan

What we advise against

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