Signs that call for underground tank leak detection
If you notice one of these signs in Alwajh, it is a good moment to talk to the team:
- The tank needs refilling faster than usual
- Damp or salt marks on the tiles above the tank
- A noticeable drop in the water level overnight
- The pump runs for longer periods
The most common causes
- A common cause: construction joints and corners.
- A common cause: cracks in the concrete tank walls or floor.
- A common cause: a float valve that does not close, so water is wasted.
Tools and methods, and when we use them
| Tool | What it finds | When we use it in Alwajh |
|---|---|---|
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | Limits: weaker with background noise and deep lines |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
From the first visit to the report
- 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.

You receive: the written level-test result and the recommended next step, in a technical report with a verification code.
Planning the visit in Alwajh
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
