How often is normal to add water an inground pool?

It depends. Some factors influencing the frequency of filling inground pools with water include:

- Climate: Pool water evaporates more rapidly in hot, dry climates than in cool, humid ones.

- Pool size: The larger the pool, the more water it will need to maintain its level.

- Pool cover: A pool cover helps to reduce water evaporation.

- Automatic pool filler: An automatic pool filler can help to maintain the pool's water level, especially in hot climates.

In general, it is normal to add water to an inground pool every few weeks or months. However, if you notice that the water level is dropping rapidly, it is important to investigate the cause and take steps to address it.
