Hidden water leaks in Al Asla, Jeddah, are worth checking before the summer heat sets in. The centre of Al Asla sits at 21.6080, 39.3101, about 15.9 km from the centre of Jeddah, and the neighbourhood covers an approximate radius of 1.2 km. Its centre sits about 112 m above sea level, and the area is about 17.9 km from the sea coast. Those facts matter because the ground here is not the same as a low coastal plot, so pipework and storage tanks can behave differently from one house to the next. The first things to look at are the water tanks, the pipe runs that leave the building, and any damp patches on ground-floor walls or slabs that have appeared without an obvious cause.

Some of the work cannot be settled from a checklist alone and is left to the site visit. The technician will need to see the actual route of the supply lines, confirm whether a leak is in a buried section or inside a wall, and judge the condition of the tank lining. Where a tank needs its internal coating looked at, the cost is set by area, typically SAR 25–65 per m², so the technician will measure the surface on the day before any figure is given. Pressure readings, meter behaviour and any signs of movement in the slab also depend on what is found when the cover is lifted, so none of these can be assumed in advance.

To help the technician, keep a note of when you first noticed damp, a higher water bill, or a drop in pressure, and whether it has grown since. Mention whether the building has a roof tank, a ground tank, or both, and when either was last cleaned or recoated. If you are near the nearest wadi channel, about 2.3 km from the centre of Al Asla, say so, since ground conditions can vary. Clear access to the tanks, the meter and the plant area will save time. Having this information ready means the visit can focus on the leak itself rather than on background questions.

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

When do you need 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

Where the problem usually comes from

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

Tools and methods, and when we use them

The steps in order

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.

Common mistakes we see

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