Underground tank leak detection for duplexes in Al Jradya, Riyadh
In short: In Al Jradya (Riyadh), underground tank leak detection for duplexes begins with the documented tank level test and the pressure test and line isolation; nothing is opened until the position is clear. The nearest wadi channel is about 0.6 km from the centre of Al Jradya (OpenStreetMap). Published price: Inspection visit, SAR 150 per visit; anything else is quoted after the inspection.

Signs that call for underground tank leak detection
The following signs are worth checking before they grow:
- Damp or salt marks on the tiles above the tank
- The tank needs refilling faster than usual
- The pump runs for longer periods
The most common causes
- Cracks in the concrete tank walls or floor.
- Construction joints and corners.
- A float valve that does not close, so water is wasted.
How we choose the tool in Al Jradya
| Method | What it helps with | Its role in Al Jradya |
|---|---|---|
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | Limits: weaker with background noise and deep lines |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
The steps in order
- Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
- Documented level test: Filling and use are stopped and the level is recorded against time.
- Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
- Checking the body and connections: Inlet, outlet and overflow connections are inspected.
- Recommendation: You get the next step in writing: repair, waterproofing or a line test.

What we advise against
- Ignoring the float valve
- Waterproofing the tank before confirming the loss is from the tank and not the line
