If you’ve decided to clean the bottom of the pool or to winterize it, you will have to empty your pool. Your reasons for emptying it are most certainly justified, but is it a good idea? And if you really have to, for how long?
How Long Should You Leave Your Pool Without Water?
Some pools can get damaged if drained and left emptied for a long time. While most modern pools can withstand a long period of emptiness, some pools have a risk of popping up if the water level in the ground is high.
Most problems requiring pool draining can be resolved within a day or two. The concrete pool should however not be left alone unfilled for an extended period. If your pool has been empty for years, then, at the minimum, you have a lot of remodeling work that must be carried out by a swimming pool construction company. In most cases, the pool could be irredeemable. But before emptying your pool at all, there are a few things you should consider.
When Should You Empty Your Swimming Pool?
There are situations where this is indeed the only solution.
Unstabilized Pool Chemical
One of the reasons you need to empty the pool water is if the chemical in your pool has become unusable, despite regular maintenance. This can happen after many years of use.
Presence of Scale in the Pool
Emptying your pool is the only solution to eliminate an enemy of swimming pools: scale. Scale, despite regular maintenance, will eventually build up on the walls and in the bottom. These deposits can eventually cause damage and affect the quality of the water. A swimming pool has to be drained for maintenance. So, this is an exceptional case with no other way around.
Winterizing Your Pool at the End of the Season
At the end of the swimming season, with the first sign of winter, you have to drain the pool. But you still don’t need to completely empty the pool. You can reduce the level but not empty it! In this case, you should know that completely emptying a swimming pool is a very bad idea.
The Need to Work on the Pool Structure
When work has to be done on the pool structure, there is no other solution than to empty the pool. This need can arise in the case of an in-ground or semi-in-ground swimming pool.
Emptying the Swimming Pool: What are the Risks?
Emptying your pool risks damaging it permanently and rendering it unusable. Your pool is constantly filled with water. The structure is therefore subjected to high water pressure. Completely emptying a swimming pool will lead to a radical change in the structure. Released suddenly from this pressure, the walls can crack or deform. In the case of an underground swimming pool, the basin could leak, move, or get popped.
The risk of an empty swimming pool deforming is quite high. Needless to say, your swimming pool would be irreparably destroyed if precautions are not taken.
In No Case Should You Leave a Concrete Pool Empty for More Than 3 Days!
Ideally, the pool should not be left completely empty for more than three days. In all cases where you need to empty the pool, operations must be carried out as quickly as possible.
Pool wintering is the only reason for draining the pool and leaving it for a long period. But still, this doesn’t require complete emptying. All you need to do is drain the pool down below the skimmer level. Winter isn’t always nice on an empty pool structure.
