Al Farwq sits in the northern part of Jeddah, centred at 21.4513, 39.2681, roughly 14.2 km from the city centre, with an approximate radius of 1.2 km. The neighbourhood is compact and largely residential, so most homes here are served by rooftop or ground-level storage tanks rather than continuous high-pressure mains, and that makes concealed leaks easy to miss until a bill or a damp patch reveals them. Its centre sits about 43 m above sea level, which means water is usually pumped up to rooftop tanks, and pump cycling is one of the first clues we check during a survey. A leak that keeps a pump running for longer than usual can point to a hidden line under a slab or behind a wall before any visible sign appears.

Al Farwq is about 9.1 km from the sea coast, and that distance matters for how we work. Humid coastal air and summer heat can speed up corrosion of older galvanised pipework and accelerate wear on float valves, so we treat seals, joints and connections in this area as likely weak points. In practice, we pay particular attention to outdoor lines, fittings near tanks and any section where the pipe has been repaired before. The inspection is planned around these conditions, so the work reaches the places most likely to fail as temperatures climb.

Before summer is the right time to check for hidden leaks in Al Farwq, because heavier household use and high temperatures put extra strain on tired plumbing. Many owners avoid common mistakes that make leaks worse or more expensive: they wait for a visible stain before calling anyone, they assume a small drip is harmless, they top up a tank without checking why the level keeps dropping, and they accept a quick patch without asking where the water is actually escaping. They also tend to skip checking the tank itself. Internal coating is priced at SAR 25–65 per m², and a failing coating can be the real source of loss, so it should be considered alongside the pipework. Early detection keeps repairs smaller, protects finishes and helps you plan the work rather than react to an emergency.

Checks before summer and before the rain season catch problems while they are still small.

Signs that call for hidden water leak detection

The following signs are worth checking before they grow:

• A water bill higher than usual with no change in use
• The meter keeps turning with every tap closed
• A hissing or trickling sound in the wall after the taps are off

Causes we see in the field

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

Tools and methods, and when we use them

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.
