1. Leakage in the drainage system: If there are any cracks, holes, or damaged pipes in the drainage system, water may leak out, causing a fall in water level during the test.
2. Blockages in the drainage system: If there are any blockages in the pipes or drains, water may not be able to flow freely through the system, leading to a decrease in water level.
3. Incorrect installation: If the drainage system was not installed properly, such as having pipes at the wrong angle or not enough slope for proper drainage, it can result in a decrease in water level during the test.
4. Evaporation: In hot and dry conditions, water in the drainage system may evaporate, causing a fall in water level.
5. Infiltration: If the soil surrounding the drainage system is porous or has cracks, water may infiltrate into the ground, leading to a decrease in water level during the test.

- Perforated pipe: If the drainage pipe is perforated, water can seep out of the pipe and cause the water level to drop. - Collapsed pipe: If the drainage pipe collapses, water will not be able to flow through the pipe and the water level will drop. - Blockage in the pipe: If the drainage pipe is blocked, water will not be able to flow through the pipe and the water level will drop. - Pump failure: If the pump that is used to drain the water fails, the water level will drop. - Power outage: If there is a power outage, the pump will not be able to operate and the water level will drop.
