Can An Inground Pool Be Left Empty?

Have you ever wondered if it’s okay to leave your inground pool empty? In this article, we’ll explore the possible risks and consequences of leaving your pool without water. We’ll also discuss the maintenance and safety measures you need to consider if you do decide to keep it empty. By the end of this article, you’ll have a better understanding of whether leaving your inground pool empty is a good idea or not.

The impact of leaving an inground pool empty

When it comes to inground pools, proper maintenance and care are key to ensuring their longevity. However, there may be times when you find yourself questioning whether it is feasible to leave your inground pool empty for a period of time. In this article, we will explore the potential risks and damages that can occur when an inground pool is left empty, as well as the precautions you can take to avoid them.

1. Damage to the pool structure

One of the main concerns when leaving an inground pool empty is the potential damage that can occur to its structure. Without the support of water, the pool shell is exposed to external pressures that can lead to cracking or shifting. The weight of the surrounding ground can have a significant impact on the structural integrity of the pool.

Effects of ground pressure on empty pools

The pressure exerted by the ground surrounding an empty inground pool can cause the pool shell to crack or shift. The weight of the soil above and around the pool puts immense pressure on the walls and bottom of the pool, leaving it vulnerable to damage.

Risk of cracking and shifting

Cracking and shifting are common issues that can occur when an inground pool is left empty for an extended period of time. These structural problems not only compromise the aesthetics of the pool but also require expensive repairs to rectify.

Long-term structural damage

Leaving an inground pool empty for an extended period can result in long-term structural damage that may be irreversible. The continuous pressure from the surrounding ground can cause the pool walls to deteriorate, leading to a weakened structure that may eventually collapse.

2. Problems with water balance

Maintaining the proper water balance in an inground pool is crucial to ensure its cleanliness and longevity. When a pool is left empty, it becomes susceptible to various water balance issues that can be detrimental to its overall condition.

Chemical imbalances and stagnation

Without water circulation, the chemicals in the pool can become imbalanced, resulting in an environment that is unsuitable for swimming. Stagnant water can lead to the growth of harmful bacteria and algae, posing health risks to anyone who comes in contact with it.

Exposure to sunlight and evaporation

An empty pool is also exposed to direct sunlight, which can cause the water to evaporate rapidly. This not only leads to a loss of water but also increases the concentration of chemicals in the remaining water, further complicating the water balance.

Algae growth and contamination

Algae growth is another issue that can arise when an inground pool is left empty. Algae spores can enter the pool through various means, such as wind or rain, and quickly multiply in the stagnant water. This can result in a pool that is contaminated and unsafe for use.

3. Potential for debris accumulation

Leaving an inground pool empty also increases the likelihood of debris accumulation, creating additional complications for pool maintenance and upkeep.

Leaves, branches, and other natural debris

Without proper water circulation, leaves, branches, and other natural debris can accumulate in an empty pool. This not only creates an unsightly appearance but also poses difficulties in cleaning and maintenance.

Difficulties in cleaning and maintenance

The presence of debris in an empty pool makes it challenging to maintain and clean the pool effectively. Removing debris from an empty pool can be time-consuming and labor-intensive, requiring additional effort to restore the pool to its desired condition.

Increased risk of clogged drains or pumps

The accumulation of debris in an empty pool can lead to clogged drains or pumps. This can result in decreased water circulation and filtration, further exacerbating the water balance issues and potentially causing damage to the pool equipment.

4. Risks of equipment damage

Leaving an inground pool empty can also have adverse effects on the pool’s equipment, such as pumps, filters, and heaters.

Effects on pumps, filters, and heaters

The absence of water circulation can cause the pool’s equipment, such as pumps, filters, and heaters, to deteriorate or malfunction. Without proper maintenance and regular operation, these essential components may require expensive repairs or even replacement.

Corrosion and deterioration of equipment

The lack of water in an empty pool leaves the pool’s equipment vulnerable to corrosion and deterioration. Moisture and exposure to the elements can cause the metal components to rust, leading to further damage and decreased efficiency.

Additional expenses for repair or replacement

The potential damage to the pool’s equipment, as a result of leaving it empty, can lead to additional expenses for repair or replacement. These costs can quickly add up and become a significant financial burden.

Precautions for maintaining an inground pool

To avoid the potential risks and damages associated with leaving an inground pool empty, it is essential to take proper precautions and implement regular maintenance practices.

Regular chemical treatments

Even if the pool is not in use, it is crucial to maintain proper chemical balance by regularly testing and treating the water. This will help prevent the growth of harmful bacteria and algae, ensuring that the pool remains safe and clean.

Proper filtration and circulation

Maintaining proper filtration and circulation is vital for an inground pool, even when it is not in use. Regularly running the pool’s filtration system will help prevent debris accumulation and maintain water clarity.

Covering the pool when not in use

To protect an empty pool from debris and the harmful effects of sunlight, it is advisable to cover it securely when not in use. This will help minimize the risk of debris accumulation, evaporation, and exposure to UV rays.

Professional inspections and maintenance

Regular professional inspections and maintenance are essential for the long-term health of an inground pool. Engaging the services of a pool professional will ensure that any potential issues are identified and addressed promptly, preventing further damage.


In conclusion, leaving an inground pool empty is not recommended due to the potential risks and damages it can cause. From structural damage to water balance issues, debris accumulation, and equipment damage, the negative impact on the pool can be extensive. To avoid these complications, it is crucial to implement regular maintenance, proper chemical balance, and adequate filtration and circulation. By taking these precautions, you can ensure the longevity and enjoyment of your inground pool for years to come.
