Hidden water leak detection in Al Mrwj, Riyadh, starts with understanding the setting. The centre of Al Mrwj sits at 24.7578, 46.6637, about 5 km from the centre of Riyadh, within an approximate radius of 2.1 km. The neighbourhood has both villas and apartment buildings, so the layout of pipework can differ quite a lot from one property to the next. Because of this mix, the first check is usually to confirm the building type and the age and route of the supply and drainage lines before any equipment is used. The ground here also matters. The centre of Al Mrwj sits about 635 m above sea level, and the nearest wadi channel is about 2.8 km from the centre, so technicians pay attention to how water may have moved through the ground over time.
Some points are left to the site visit itself. The technician will walk the property, look at the water meter behaviour, check visible signs such as damp patches, staining or softened plaster, and decide which detection method suits the pipes and walls in front of them. Whether a leak sits under a slab, behind a wall or along an external run can only be judged on the spot. The same applies to the condition of any water tank. If the tank needs attention, the internal coating is priced at SAR 25–70 per m², but the area to be coated can only be measured once the tank has been inspected in person, so no figure should be assumed in advance.
To help the technician arrive prepared, it is useful to have a few details ready. Note the property type, whether it is a villa or an apartment, and roughly when the building was constructed. Record when you first noticed the problem, whether the water bill has risen, and where you have seen damp or unusual sounds. Share any previous plumbing repairs and the location of main isolation valves. Clear access to the meter, the tank, and the areas where you suspect water is escaping will let the visit proceed efficiently and without unnecessary disruption.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
Signs worth paying attention to
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
Causes we see in the field
- A hot line that expands and contracts with use.
- A cracked pipe under floor tiles.
- A corroded joint inside a wall.
How we choose the tool in Al Mrwj
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Meter test with all use stopped | Whether water is being lost after the meter | Limits: does not locate the leak by itself |
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
| Thermal camera | The warm or cold trace of water on a surface | Limits: needs a clear temperature difference |
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | Limits: weaker with background noise and deep lines |
The steps in order
- Meter test: We stop all use and watch the meter to confirm whether water is actually being lost.
- Line isolation: We close valves one line at a time to see which line loses pressure.
- Acoustic listening: We follow the sound of water escaping under pressure and compare its strength between points.
- Thermal imaging and moisture mapping: We map how far the wet area spreads behind paint and tiles.
- Documentation: Readings, photos and the likely position go into a written report.
