Picture a family who owns a second-floor apartment in a multi-storey block and rents it out. Nothing looks wrong, yet the monthly water bill has crept up, a patch of paint near the bathroom has started to bubble, and a faint musty smell comes from the kitchen cupboard. For this kind of owner, a hidden leak can spread through walls, ceilings and floors for weeks before anyone sees a stain, and by then the repair is far larger than it needed to be.

Al Mrwa sits at about 652 m above sea level, roughly 19.4 km from the centre of Riyadh, and its centre lies at 24.5387, 46.6741 with an approximate radius of 1.2 km. The nearest wadi channel is about 2.8 km away. For owners here, the practical meaning is that the area's ground and water conditions are worth checking carefully, and that the building's own water system, including rooftop and ground-level tanks, deserves regular attention. Pipes run through shared shafts and concrete slabs, so a leak in one flat can travel to neighbouring units, which makes early detection a matter of protecting the whole building rather than a single apartment.

A sensible approach starts with the meter. Read it before going to bed and again after waking, when no tap has been used; a rise in that reading points to a leak somewhere in the system. Next, check the visible points: under sinks, behind toilets, around the water heater, and the joints of flexible hoses. Look at ceilings and walls for soft plaster or discolouration, and note any change in water pressure. If the signs persist, inspect the storage tank. Where coating is due, obtain quotes that state the internal coating rate, which is listed at SAR 25–70 per m², and compare them on the work included rather than the figure alone. Finally, keep a simple record of readings, repairs and dates, so that any future change can be spotted quickly and the owner can act before damage reaches the neighbours.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

When do you need hidden water leak detection?

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

• 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
• The meter keeps turning with every tap closed

Where the problem usually comes from

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

How we choose the tool in Al Mrwa

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.
