What Happens When You Keep A Pool Empty For Too Long?
Cracking and damage: One of the biggest problems with leaving a pool empty for too long is the potential for cracking or other forms of damage to the pool structure. Without the support of water, the walls and floor of the pool can shift and crack, causing significant damage that can be expensive to repair.
Bacterial growth: When a pool is empty for an extended period, it can become a breeding ground for bacteria and other harmful organisms. Without proper maintenance, stagnant water can quickly become contaminated, potentially posing health risks to anyone who comes in contact with it.
Damage to pool equipment: Leaving a pool empty for an extended period can also cause damage to pool equipment such as pumps, filters, and heaters. This is because the lack of water can cause seals and other components to dry out, leading to potential leaks and other issues when the pool is refilled.
Structural issues: In addition to cracking, there are other structural issues that can occur when a pool is left empty for too long. For example, the walls of the pool can start to bow inward due to the pressure of the surrounding soil. This can cause significant damage that may require extensive repairs.
Increase in maintenance costs: When a pool is left empty for too long, the costs of maintaining and repairing it can quickly add up. From repairing damage to the pool structure to replacing damaged equipment, the longer a pool sits empty, the more expensive it can become to get it up and running again.
Damage to the Pool Structure
Cracking: Keeping a pool empty for too long can cause the pool shell to crack. When the pool is drained, the water pressure is released, and the ground can shift, which can cause the pool to crack. Once the pool shell is cracked, it can be expensive to repair.
Floating: An empty pool can float out of the ground. When a pool is empty, there is nothing to weigh it down. The hydrostatic pressure from the water table can cause an empty pool to lift out of the ground, causing structural damage and making it unusable.
Tile damage: Pool tiles can loosen and fall off when a pool is empty. The glue used to attach the tiles to the pool shell can dry out and become brittle, causing the tiles to fall off. Replacing tiles can be a costly and time-consuming process.
Plumbing damage: Leaving a pool empty for an extended period can cause damage to the pool’s plumbing system. Pipes can dry out and become brittle, which can cause them to crack or break when the pool is refilled. This can lead to costly repairs and possible leaks.
Cracking and Drying Out of the Pool Surface
Cracking and drying out of the pool surface are two common problems that can occur when a pool is kept empty for too long. When a pool is drained, the sun and heat can cause the surface of the pool to dry out and crack. This can cause damage to the surface of the pool, making it more difficult to repair in the future. It is important to keep the pool surface moist and hydrated to prevent these problems.
Pool surface material also plays a crucial role in determining how long a pool can be kept empty. Concrete pools are more likely to crack and develop leaks when left empty for extended periods, while fiberglass and vinyl pools are more resistant to damage. However, regardless of the pool’s surface material, keeping it empty for too long can lead to cracking and drying out.
Weather conditions can also impact how quickly a pool surface dries out and cracks. In hot and dry climates, pools may dry out and crack faster than in more moderate or humid conditions. It is important to monitor the weather conditions when deciding how long to keep a pool empty and take appropriate measures to prevent damage.
To avoid cracking and drying out of the pool surface, it is recommended to keep the pool filled with water or cover it to prevent sunlight and heat exposure when not in use.
Increased Risk of Groundwater Damage
When a pool is empty for an extended period, the surrounding groundwater can pose a significant risk to the pool’s structure. As the pool sits empty, groundwater can begin to seep into the space left by the pool water, causing the soil around the pool to become overly saturated.
This excess moisture can cause significant damage to the pool’s foundation, leading to instability and even collapse. Additionally, the excess groundwater can cause soil erosion around the pool, which can compromise the integrity of the pool’s walls and floor.
If you are planning to keep your pool empty for an extended period, it is crucial to take steps to prevent groundwater damage. One of the most effective ways to protect your pool is to ensure that the area around it is well-drained, with no standing water or excessive moisture. You may also want to consider hiring a professional to install a drainage system to redirect groundwater away from the pool area.
It’s essential to act quickly if you suspect groundwater damage to your pool. Signs of groundwater damage may include cracking or buckling in the pool’s walls or floor, or the presence of standing water around the pool. If you notice any of these signs, it’s crucial to address the issue as soon as possible to prevent further damage.
Ultimately, the best way to avoid groundwater damage to your pool is to avoid keeping it empty for too long. By taking steps to maintain your pool’s water level, you can protect it from the risks associated with extended periods of emptiness.
