The debate about whether pool returns should be open or closed has been a longstanding issue among pool owners and maintenance professionals. While some argue that open returns are more efficient, others claim that closed returns provide better performance and safety. In this article, we will delve into the world of pool returns, exploring the benefits and drawbacks of both open and closed systems, and provide guidance on how to make the best decision for your pool.
Understanding Pool Returns
Pool returns, also known as outlet fittings, are the components that direct water back into the pool after it has passed through the filtration system. They play a crucial role in maintaining the circulation of water, ensuring that the pool is clean, clear, and safe for swimmers. The type of return used can significantly impact the overall performance of the pool, affecting factors such as water quality, energy efficiency, and equipment longevity.
Open Pool Returns
Open pool returns, also known as “eyeball” returns, are the most common type of return used in swimming pools. They consist of a fitting that is installed in the pool wall, typically at the bottom or on the sides, and direct water back into the pool through a small opening. The water flows out of the return in a directional pattern, creating a gentle circulation of water.
One of the main advantages of open returns is their ability to provide a high flow rate, which can be beneficial for large pools or those with high bather loads. Additionally, open returns are relatively inexpensive to install and maintain, making them a popular choice among pool owners.
However, open returns also have some drawbacks. One of the main concerns is the potential for entrapment, which occurs when a swimmer becomes trapped against the return fitting, causing injury or even death. To mitigate this risk, many pool owners and manufacturers recommend installing anti-entrapment devices, such as grate covers or safety screens, which can help prevent entrapment and improve overall safety.
Closed Pool Returns
Closed pool returns, also known as “stub” returns, are a type of return that is installed in the pool floor or walls, but unlike open returns, they do not direct water back into the pool through a small opening. Instead, they use a network of pipes and fittings to distribute water throughout the pool, creating a more even circulation pattern.
One of the main benefits of closed returns is their ability to provide a more efficient circulation pattern, which can help reduce energy costs and improve overall pool performance. Closed returns also eliminate the risk of entrapment, as the water is directed through a network of pipes rather than a small opening.
However, closed returns can be more expensive to install and maintain than open returns, and may require additional equipment, such as valves and fittings, to control the flow of water. Additionally, closed returns may not provide the same level of flow rate as open returns, which can be a concern for large pools or those with high bather loads.
Factors to Consider When Deciding Between Open and Closed Pool Returns
When deciding between open and closed pool returns, there are several factors to consider. These include:
Pool Size and Shape
The size and shape of the pool can have a significant impact on the type of return used. For example, large pools or those with complex shapes may require multiple returns to maintain adequate circulation, while smaller pools may be able to use a single return.
Bather Load
The bather load, or the number of swimmers using the pool, can also impact the type of return used. Pools with high bather loads may require more powerful returns to maintain adequate circulation and water quality.
Equipment and Maintenance
The type of equipment used in the pool, such as pumps and filters, can also impact the type of return used. Additionally, maintenance requirements, such as cleaning and inspection, should be considered when deciding between open and closed returns.
Comparison of Open and Closed Pool Returns
The following table provides a comparison of open and closed pool returns:
| Type of Return | Flow Rate | Entrapment Risk | Installation Cost | Maintenance Cost |
|---|---|---|---|---|
| Open Return | High | High | Low | Low |
| Closed Return | Lower | None | Higher | Higher |
Conclusion
In conclusion, the decision to use open or closed pool returns depends on a variety of factors, including pool size and shape, bather load, equipment, and maintenance requirements. While open returns offer high flow rates and are relatively inexpensive to install and maintain, they also pose a risk of entrapment. Closed returns, on the other hand, provide a more efficient circulation pattern and eliminate the risk of entrapment, but may be more expensive to install and maintain. By considering these factors and weighing the benefits and drawbacks of each type of return, pool owners can make an informed decision that meets their specific needs and ensures a safe and enjoyable swimming experience.
It is also worth noting that many pool owners are now opting for a combination of both open and closed returns, which can provide the benefits of both systems. For example, using open returns in areas of the pool where high flow rates are needed, and closed returns in areas where a more efficient circulation pattern is desired.
Ultimately, the key to optimizing pool performance is to understand the specific needs of your pool and to make informed decisions about the type of return used. By doing so, pool owners can ensure a safe, efficient, and enjoyable swimming experience for years to come.
What are pool returns and how do they impact pool performance?
Pool returns refer to the outlets through which water is circulated back into the pool after passing through the filtration system. The performance of pool returns has a significant impact on the overall efficiency and hygiene of the pool. When pool returns are functioning correctly, they help to distribute clean water evenly throughout the pool, which in turn maintains clean and safe water for swimmers.
