If you must drain the pool for maintenance or repairs, it's crucial to refill it as soon as possible to preserve its integrity. Always consult with a pool professional for specific guidance based on your local conditions.
The first thing you have to look out for is that there isn't to much ground water out side the pool say when its raining or just after rain. because water may be able to build up under the pool and lift it up out of it proper position.

In South Florida, a concrete pool can typically be empty for a few weeks without significant issues, but prolonged emptiness—especially over a month—can lead to structural problems. The risk of the pool lifting, known as hydrostatic uplift, increases if groundwater levels are high, as the buoyant force can act on the empty pool. To mitigate this risk, it's advisable to monitor groundwater levels and consider draining the pool only during dry seasons or with proper precautions.
