Underground tank leak detection for duplexes in Yanbu
In short: In Yanbu (Yanbu), 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 centre of Yanbu sits about 6 m above sea level (SRTM open elevation data). Pricing starts from Inspection visit (SAR 150 per visit), and other items are quoted after the visit.
Before we start: what we know about Yanbu
Team note on Yanbu: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. Main roads in or near Yanbu: King Abdulaziz Road, Umluj Road, Al Hanan Street.
The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data). Yanbu is about 1.2 km from the sea coast (OpenStreetMap).
In a duplex, the two floors often share lines, so tests are done floor by floor.
Signs that call for underground tank leak detection
These are the signs most often linked to underground tank leak detection:
- A noticeable drop in the water level overnight
- The pump runs for longer periods
- The tank needs refilling faster than usual
- Damp or salt marks on the tiles above the tank
Causes we see in the field
- A float valve that does not close, so water is wasted.
- Construction joints and corners — we check this before anything else.
- Cracks in the concrete tank walls or floor.
How we choose the tool in Yanbu
| Method | What it helps with | Its role in Yanbu |
|---|---|---|
| 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 |
| 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 |
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.
