When things go wrong in your swimming pool it can seem like emptying it is the logical thing to do in order to conduct repairs.
However this is exactly the wrong thing to do!
When a swimming pool is full of water the concrete tank is stable. However, by draining it several things can happen that will de-stabilise the structural integrity of the tank and this can lead to further problems.

There are several considerations to take into account when you drain your swimming pool:
Cost of water disposal
Draining the pool is costly as the water needs to be disposed of responsibly. It can’t be emptied into the nearest storm drain! Pumping a swimming pool dry is an expensive exercise and can require a permit to dispose of the water.
Water in the swimming pool has a weight that pushes down on the swimming pool tank. If the surrounding water table is high and the water removed from the pool, you could end up with your swimming pool breaking free to float like a boat. This will result in your pool breaking itself apart.
If a pool is emptied the tiles and grout will dry out. This can result in the tile adhesive shrinking which can lead to the tiles de-bonding.
If a pool is drained it will be subject to temperature change. This will affect the tile sizes as they will grow larger when warm and shrink when cold. This can cause the tiles to de-bond.
Loss of revenue
When a swimming pool is drained it cannot earn any revenue. This can result in your customers going elsewhere to swim, and they may not come back. By keeping your pool full of water it can remain in use and you can retain your customer loyalty.
Refilling an empty pool must be done carefully. The re-introduction of water will rehydrate the grout and adhesive, making it expand. This can cause tiles to de-bond. The temperature will initially be cold as the water is put back in. This must be heated slowly to prevent tiles expanding too quickly and becoming de-bonded. The weight of water going back into the pool will put pressure on the tank that may cause movement. This can introduce cracks.
