What is specific about Al Rwys for hidden water leak detection

The centre of Al Rwys is at 21.5172, 39.1714, about 2.9 km from the centre of Jeddah, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. Main roads in or near Al Rwys: Hail Street, Al Andalus Road, King Abdulaziz Road.

The centre of Al Rwys sits about 9 m above sea level (SRTM open elevation data). Al Rwys is about 1.3 km from the sea coast (OpenStreetMap).

Hidden water leaks in homes around Al Rwys, Jeddah, most often show up as a sudden rise in the water bill, damp patches on walls or floors that have no obvious source, or a faint sound of running water when all taps are closed. Because the leak sits inside walls, under tiles or in buried pipework, owners usually notice the effect long before they find the cause. The most common culprits in this type of property are pinhole leaks in supply lines, failed joints behind bathroom fittings, and slow seepage from storage tanks on the roof or at ground level.

Local conditions shape how we approach the search. The centre of Al Rwys sits at 21.5172, 39.1714, about 2.9 km from the centre of Jeddah, which places it within the wider city network but at a practical distance from the central water mains. The area is roughly 1.2 km in radius, so buildings within the same neighbourhood often share similar supply arrangements and tank setups, making a pattern-based check useful. Its elevation of about 9 m above sea level means that pressure in the lines is shaped by pumps and tanks rather than gravity alone, so we check pump cycling and tank float behaviour alongside the pipework. Al Rwys is also about 1.3 km from the sea coast, so the salty, humid air can accelerate corrosion on exposed fittings and metal brackets. For water tanks, internal coating work is priced at SAR 25–65 per m², and whether a tank needs recoating is one of the first things we assess when seepage is suspected.

Before the visit, ask whether the property is fed from a roof tank, a ground tank with a booster pump, or both, and when the tank was last cleaned or recoated. Ask which areas show damp and whether the water meter still moves when every tap and appliance is switched off. Note any change in the bill over recent months, and mention any recent plumbing or tiling work, since disturbed pipes are a frequent source of new leaks. Having these details ready lets the technician plan the right tests and avoid unnecessary opening of walls.

Each job ends with a written report that carries a verification code you can check on our site.

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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

Causes we see in the field

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

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.
