Think your water bill has jumped and you can't see a single drip? In Al Rwda, Riyadh, hidden leaks are a common cause, and they are worth treating as an emergency when you suspect water is escaping behind walls, under floors or beneath the slab. Al Rwda sits at about 24.7341, 46.7672, roughly 9.6 km from the centre of Riyadh, and its built-up area covers an approximate radius of 2.9 km. The neighbourhood is mainly apartment buildings, so a leak in one flat can affect shared pipes, the building's tank and the units around it. The centre of Al Rwda sits about 622 m above sea level, which is a useful reminder that water pressure and tank arrangements vary from block to block, so the source of the problem is not always where the damp patch appears.

When a technician visits, the inspection usually starts with a review of the symptoms: where the water pressure has dropped, where the bill has risen, and whether the sound of running water continues when all taps are closed. The technician then checks the main supply lines, the valves and the connections that serve your unit, and uses listening and pressure methods to narrow down the likely area. Where the leak is behind a wall or under a floor, the team works to locate the exact spot before any opening is made, so that the damage to finishes is kept as small as possible. If the water storage tank is part of the problem, the inspection also covers its condition, and where its internal lining has deteriorated, the cost of tank internal coating is quoted per square metre at SAR 25–70 per m², depending on the work needed.

Before the visit, gather your recent water bills, note the date you first noticed the problem and what you observed, such as damp patches, a warm floor spot or a drop in pressure. Clear access to the kitchen, bathrooms, store room and any shaft or ceiling where pipes run, and make sure the building's water valves and your unit's isolation valve are easy to reach. If you have the building or tank records, have them ready, and keep pets and children away from the work area. Being prepared helps the technician find the leak faster and gives you a clear picture of what needs to be done.

If water is flowing, close the main valve first, then call or message with photos.

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.
