Swimming pool leak: How to locate it?

Leaks are a common problem that can affect any pool owner. Repairing them is one thing, but detecting them is another. This mission can prove to be more complex than expected. To achieve this, you can choose to call in a professional or attempt a self-diagnosis.

And what if it wasn’t a leak?

You are concerned because the water level in your pool is starting to decrease slightly. This does not necessarily mean there is a leak. This phenomenon can simply be the result of water evaporation, especially during hot days. The water temperature then exceeds that of the air.

However, if the drop becomes excessive, it could indeed be a leak. To clear any doubt, you can use a natural method. For this, all you need is a container and a pen. Place the container filled with water on a step of the pool. Then, use your pen or marker to mark the water level. After 24 hours, compare the decrease in level with that of your pool. If you notice a significant drop, you could conclude that there is indeed a leak. On the other hand, if the levels are identical, the hypothesis of simple evaporation would be confirmed.

What can be the causes of a leak?

The reasons for a leak can be varied. By identifying its origin, detection will be easier. The leak can occur because of a faulty fitting in the filtration system. It can also be due to a crack in the lining. Finally, it is important not to ignore the possibility of a leak in the hydraulic system or in the underground pipes.

The leak is there, but how to locate it?

If your pool has a leak, the first reflex is to turn off the filtration system to determine the origin of the flow. It is therefore essential to let the water level drop gradually. Once lowered, you will be able to see the location of the leak for yourself. This may be located under the skimmers or at the level of other specialized fittings such as the return jets.

If you would like additional details, you can also consider using a leak detector designed for piping. This tool will allow you to hear the sound of the leak while identifying its source in the conduits. Level sensors as well as electronic detectors for liners are also available.

For added safety, it may be wise to call in a professional. Equipped with suitable tools, the latter can solve your problem, whether it is a leak or a crack. In addition to the intervention, you will receive practical advice regarding the maintenance of your pool.
