Underground water and fuel tanks at duplexes most often fail quietly. A slow seep through a corroded seam or a cracked fitting can drain water for weeks before anyone notices a drop in pressure or a damp patch in the yard. For duplex owners sharing one tank between two households, the question is rarely whether a leak exists, but how long it has been running and which half of the building is paying for it.

In Am Al Hmam Al Shrqy, the local setting shapes how a leak check should be planned. The centre of the area sits at 24.6828, 46.6593, about 3.8 km from the centre of Riyadh, with an approximate radius of 1.2 km, so most properties here are a short drive from the city but still have their own private utility layout. The centre is also about 618 m above sea level, according to SRTM open elevation data. Elevation affects how water and pressure move through the lines, so a technician should check the pressure at the pump and at the tank outlet before assuming the fault is in the ground, not in the plumbing above it.

If a tank needs repair work, the inside coating is often part of the job. Tank internal coating is priced at SAR 25–70 per m², so the size of the tank and the condition of its walls will largely decide the final figure. Ask the provider to measure the tank and state the area in writing before any coating starts.

Before the visit, ask the provider to confirm whether the test will be done with the tank full or partly empty, since a leak is easier to detect under pressure. Ask who will be present, how the two households will be informed of the findings, and how the cost will be split between the two units. Request a written list of the tests to be run and a clear description of what will be checked at each step.

In a duplex, the two floors often share lines, so tests are done floor by floor.

Signs worth paying attention to

If you notice one of these signs in Am Al Hmam Al Shrqy, 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

• Construction joints and corners.
• Cracks in the concrete tank walls or floor.
• A float valve that does not close, so water is wasted — we check this before anything else.

Tools and methods, and when we use them

The steps in order

1. Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
2. Documented level test: Filling and use are stopped and the level is recorded against time.
3. Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
4. Checking the body and connections: Inlet, outlet and overflow connections are inspected.
5. Recommendation: You get the next step in writing: repair, waterproofing or a line test.
