A pool that’s losing water can quickly become a costly problem if the leak isn’t identified in time. Slight evaporation is normal, but an abnormal drop in water level may indicate a leak in the pool, pipes or filtration system. To pinpoint the source of the problem, a number of tests can be carried out before repairs are considered.

Checking evaporation with the bucket test

Before suspecting a leak, it’s important to make sure that the drop in water level isn’t simply due to evaporation. The bucket test allows you to compare the loss of water from the pool with that from a container placed on the edge of the pool. Simply fill a bucket with water, place it on a submerged step and mark the water level inside and outside the bucket. After 24 hours, if the pool has lost more water than the bucket, a leak is likely.

Visual inspection of pool and equipment

A thorough check of the pool lining can sometimes reveal cracks or deteriorated joints. Coping stones, skimmers, discharge nozzles and the liner should be inspected for signs of wear or unusual moisture around the pool. Leaky pipes can also manifest themselves as abnormally damp areas of ground or settling around the pool.

Dye test for leak detection

If a suspect crack or joint is identified, a dye test can help confirm the presence of a leak. By gently approaching a liquid dye near the suspect area, it’s possible to observe whether liquid is being drawn into a crack or hole, indicating water loss.

Testing hydraulic circuits

If no visible problem is detected on the pool structure, the leak may be in the filtration system or the pipes. A first test is to observe whether the leakage continues when the pump is switched off. If the water loss stops, the problem probably lies in the filtration system. A professional can then carry out a pressure test on the pipes to detect any underground leaks.

Conclusion

A pool that loses too much water may be hiding a leak in the lining, pipes or filtration system. Simple tests such as the bucket test, visual inspection or dye test can be used to identify the source of the problem. In case of doubt, professional intervention guarantees precise location and appropriate repair.
