Before any hidden water leak is looked at in Al Rwda, Riyadh, the first thing to check is the setting itself. The centre of Al Rwda sits at 24.7341, 46.7672, about 9.6 km from the centre of Riyadh, and the district covers an approximate radius of 2.9 km. Because the area is mainly apartment buildings, a leak is rarely confined to one unit. Pipework often runs through shared shafts, ceilings and walls, so the first questions are which unit or floor is affected, whether neighbouring apartments show dampness, and whether the problem appears to be in the building's common supply or in a single flat. The ground here sits about 622 m above sea level, which is noted in the reference data, and the technician will simply factor in the local water arrangements when planning the visit.

Several things are deliberately left to the site visit. The technician needs to confirm the actual route of pipes behind finishes, the condition of any tank and its internal coating, and whether the sound, damp patch or meter movement points to a true leak or to something else. Quotations for tank internal coating are commonly given per square metre, in the range of SAR 25–70 per m², but the final figure depends on the size and condition of the tank that is found on the day. Nothing should be bought or agreed until the technician has examined the actual layout and reported back in person.

To help the technician arrive prepared, it is useful to have a few details ready. Note which room or wall shows the damp or sound, when you first noticed it, and whether it is worse at certain times. Have your floor and flat number, and say whether the building has a shared water tank on the roof or at ground level. Tell them if any work has been done recently on the plumbing, and whether you have a previous water bill that shows an unusual rise. Clear access to bathrooms, kitchens, shafts and the tank area will save time and make the first inspection more accurate.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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 hot line that expands and contracts with use.
• A common cause: a corroded joint inside a wall.
• A common cause: a cracked pipe under floor tiles.

How we choose the tool in Al Rwda

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.
