Otherwise, your pool is best maintained when you can keep the proper water level year-round. An empty pool (or as little as 1/4 filled) and an exposed liner on a hot day can cause the liner to shrink from the heat and deem the liner useless. An empty pool is also susceptible to collapse.
When one drains the pool and there happens to be water under the shell (like in the rainy spring when people want to clean up the pool) the entire pool shell can heave. This is because the water under the pool creates an upward hydrostatic force (through buoyancy) and the pool is lifted out of the ground.
The answer is always NO. Above ground pools need the weight of the water in them to provide an optimal level of stability. Without water supporting the wall you run the risk of the pool wall coming out of the track. Also without water in the pool the liner can shrink and no longer fit your pool.
An empty swimming pool can pop, or float out of the ground. This is due to possible hydrostatic pressure from unknown underground water.
If high groundwater is present in your area, it is best to only partially empty your pool.

The best practice is to partially drain these types of pools.
If ground water is not a problem a pool can be left empty for weeks or even months as long the hydrostatic relief in the bottom of the pool is open and functioning. If the time frame of the pool being empty gets into freezing weather there is real risk of freeze-thaw damage to surface of the pool.
The average outdoor spigot on a home can produce up to 12 gallons per minute. A small pool can be filled in a few hours, while a large one can take 14 hours.
The weight of ice or snow are common culprits of pool collapse. Draining your pool too much. An older inground pool may not be able to withstand the weight of dirt against it once it is empty or if the water levels are too low. Groundwater can also push against the pool walls and cause it to collapse.
Vinyl pools tend to contract when emptied, which can result in damage when they are refilled. Gunite or fiberglass pools can crack, and fiberglass pools may suffer bulging or splitting if drained.
Inground pools made of concrete or gunite are susceptible to popping out of the ground if drainage is not done properly. If there has been a surplus of rain recently or your pool is located in a wet area, it is best not to try and drain the pool yourself at all.
When too much pool water soaks into the ground, the resulting upward water pressure could crack the bottom of your pool or cause it to float right out of the ground.
By not draining it, you'll save money and help out the environment at the same time. Keeping water in the pool helps to prevent the liner from drying out, shrinking and cracking. ... Water provides a protective barrier that greatly prevents the need for costly repairs each year.
Pool Collapse – An above ground pool collapse is often caused by the results of ice damage, but it can also happen when there is too much snow accumulated on top of the pool and the frame cannot handle the weight.

A sinkhole can occur whether you have an inground pool or an above-ground pool. A pool that is allowed to leak into the foundation underneath can lead to a very large, very dangerous sinkhole. In fact, leaking water is the main cause of a sinkhole. Sinkholes start developing a long time before they actually appear.
Major Issues with an Unlevel Pool

Flooding Your Grass Is Not A Good Idea

When this happens, it will become difficult to balance your pool water.
