If a water line breaks or leaks under or near a pool the soil may become fully saturated over time. When the saturation reaches a point, that there is sufficient water under the pool, it may cause the pool to float or pop up.
Answer: You have several choices. The best solution is to remove both the deck around the pool and the screen enclosure (if the pool is screened). Then disconnect all electrical and plumbing attachments, drain and lift the existing pool, dig, re-level and reinstall the pool to the proper grade.
If the pool has been improperly installed on sloping ground, even the weight of the pool water itself can be enough to cause a collapse. Moreover, the metal fasteners holding the frame together don't last forever. They can corrode and fail.
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.
Pool Overflowing From Rain
Rain, by itself, normally wouldn't harm your pool. However, as rain falls, it deposits pollen and other particles in the air onto the ground and into your pool. Any runoff into your pool will also contain contaminants, which can quickly turn your relaxing, beautiful oasis into a mess.
A popped or floating pool is a swimming pool that has risen out of the ground. Popped pools are not an everyday happening, but when they take place, they may result in irreversible damage to your pool.
Pool industry experts recommend you drain your pool and refill it every five to seven years. No two pools are alike, so there is no set number at which you must drain your pool.
How long can you leave a pool empty? Well, the minimum amount of time possible in order to minimize the risk of serious damage. Most issues that require a pool drain will take at least a day or two to resolve, but it's recommended to not let it sit empty for any extended period of time.
Thankfully, the pool pop up rarely happens. In fact, it's an extremely rare occurrence, and it usually happens when there's a major flooding event or hurricane in the area, which saturates the ground and creates a super high water table.
Pool pop-ups are quite common in areas with high water tables. A pool pop-up occurs when a pool “floats” out of the ground because of the hydrostatic pressure of ground water seeping into the pool excavation under the pool shell.
“Hydrostatic pressure is the pressure exerted by a fluid at rest due to the force of gravity. It's the pressure you feel when you dive to the bottom of a swimming pool.
Close the pool for winter – but don't drain it.
In winter, the water in your pool is still your friend. Especially when properly winterized, it helps to protect the pool liner, keep it clean and prevent unnecessary damage from debris, harsh weather and other factors.
Maintenance is critical when it comes to the quality of your pool water. Well maintained pool water can last up to 5, maybe even seven years before you need to replace it. This means weekly cleaning, functional filters, and checking ph levels every day.
Most inground fiberglass and concrete pools are built structurally to withstand the weight of the dirt against them when drained. However, if the groundwater is high enough, it can push the entire pool out of the ground. The pool shell acts like a ship and floats up in the groundwater.
Pools require a lot of maintenance, but luckily, they do not need to be drained very often. However, there are a few circumstances in which it is necessary to completely or partially drain your pool. These reasons usually have to do with water quality or repair needs.
Hydrostatic pressure, or water pushing upwards, is the reason why pools can pop up out of the ground. To alleviate this problem, the majority of concrete pools are built with a hydrostatic relief valve.
If your pool pump manufacturer has declared your pump is rain safe, you can leave it on in rainfall. Nevertheless, during a thunderstorm, it is highly recommended that you switch off and unplug your pool pump to prevent any costly and irreversible damages to your pool equipment.
Pool Losing Water After Heavy Rain
Due to a heavy rainstorm, water loss is more common with vinyl liner pools that can be damaged, come loose, or float to the top. With other types of inground pools, it is vital to get the water level down. If not drained, the water balance will change, causing cloudy water and more.
Drain the water down to no more than 6 inches from the bottom of the skimmer if you plan to use a standard floating winter cover. Use your pool filter, switched to the "Drain" setting, to empty the pool water.
Another reason for a pool to lose water over the winter is due to the harsh elements. Ice, snow, and water can accumulate on top of the pool cover. When too much weight forces the pool cover into the surface of the pool, water may rise up and over the pool sides. This is called displacement.
A common question asked is, “Can above ground pools stay up year round?” And although the easy answer is that “Yes, they can,” whether you want to leave them up year-round really depends on the type of pool you have. Dismantling some above ground pools for the winter may be more hassle than it's worth.
