Many property owners in Al Adl, Jeddah ask whether a hidden water leak is worth looking for before it shows up on the water bill or as damp on a wall. Al Adl is a neighbourhood with its centre at 21.4461, 39.2907, about 16.3 km from the centre of Jeddah, and it covers an approximate radius of 1.2 km. Its centre sits about 58 m above sea level and roughly 11 km from the sea coast. Those location details matter little to a leak itself, but they explain why many homes here have rooftop water tanks and long pipe runs that can hide faults for months. For tank work specifically, internal coating is priced at SAR 25–65 per m², so the surface area of the tank is the main factor in any quote for that repair.

The inspection normally starts with a conversation about where the water is going: a rising meter reading, a damp patch, a smell, or a sound in the wall. The technician then checks the main supply and the property's internal pipes, looking at how the meter responds when all taps are closed. Where a leak is suspected inside a wall or under a floor, listening equipment and moisture readings help narrow the area before anything is opened up. Rooftop and ground-level tanks are checked for seepage, cracks and failing internal coating, and the tank's surface area is measured so the coating cost can be worked out per square metre at the rates above. Each step is recorded so the owner can see what was tested and what was found.

Before the visit, it helps to have the water bills for recent months ready, along with a note of when the readings started to rise. Clear access to the tank, the meter, the kitchen and the bathrooms saves time, and any previous plumbing or tank repair records are useful to pass on. Keep taps and appliances switched off during the inspection so the meter can give a clean reading. If there is visible damp, take a dated photo before it dries. Having these details in hand lets the technician focus on the likely source of the leak in Al Adl and gives you a clearer picture of the work needed.

How we choose the tool in Al Adl

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.
