A pool’s filtration system is crucial, and one component to consider is the low suction pool skimmer. Understanding how fluid dynamics principles affect its performance is key. The Association of Pool & Spa Professionals (APSP) publishes safety standards that provide valuable guidance. Properly installed and maintained, a low suction pool skimmer can minimize the risk of entrapment, an issue addressed by pool safety advocates, making it a potential option for families.

Understanding Low Suction Pool Skimmers: A Guide to Choosing the Right One
Choosing the right pool equipment can feel overwhelming. One crucial element is the pool skimmer. This guide will help you understand what a low suction pool skimmer is, how it differs from traditional skimmers, and whether it’s the right choice for your pool. We’ll specifically focus on "low suction pool skimmer" advantages and disadvantages, addressing key considerations to help you make an informed decision.
What is a Low Suction Pool Skimmer?
A low suction pool skimmer is designed to minimize the amount of suction force applied to the water entering the skimmer. Unlike traditional skimmers that rely on a stronger suction to pull debris from the surface, low suction models use a gentler flow. This reduced suction is primarily designed for safety and to address concerns related to entrapment hazards.
How Low Suction Skimmers Differ From Traditional Skimmers
Suction Force
The primary difference lies in the amount of suction generated.
- Traditional Skimmers: These use a stronger suction to quickly remove debris.
- Low Suction Skimmers: These use a reduced suction force.
Safety Considerations
- Traditional Skimmers: While advancements have been made, older models can pose a higher risk of entrapment.
- Low Suction Skimmers: By design, the reduced suction significantly lowers the risk of entrapment, particularly for children or individuals with limited mobility. This can be enhanced with the use of a Safety Vacuum Release System (SVRS).
Debris Removal Efficiency
- Traditional Skimmers: Generally more efficient at removing larger amounts of debris quickly.
- Low Suction Skimmers: May require slightly more time to remove debris, especially larger items, but can be just as effective.
Advantages of Using a Low Suction Pool Skimmer
Using a low suction pool skimmer offers several compelling benefits:
- Enhanced Safety: Significantly reduces the risk of entrapment, providing peace of mind, especially for families with young children.
- Compliance with Safety Standards: Many jurisdictions require or strongly recommend low suction skimmers or SVRS systems to meet safety regulations.
- Compatibility with Variable Speed Pumps: Low suction skimmers often work more efficiently with variable speed pumps, allowing for energy savings and quieter operation. The lower suction doesn’t impede the pump’s ability to operate at lower, more efficient speeds.
- Reduced Strain on Pump: The reduced suction puts less strain on the pool pump, potentially extending its lifespan and reducing maintenance costs.
Disadvantages of Using a Low Suction Pool Skimmer
While low suction skimmers offer numerous advantages, there are also some potential drawbacks to consider:
- Potentially Slower Debris Removal: The reduced suction may result in a slightly slower debris removal rate, especially for larger or heavier items. Regular skimming may be required.
- Higher Initial Cost: Low suction skimmers or SVRS systems can sometimes have a higher initial purchase price compared to traditional skimmers.
- Maintenance Needs: A low suction skimmer still requires routine maintenance. You’ll still need to regularly clean out the skimmer basket to prevent clogs and maintain optimal performance.
Is a Low Suction Pool Skimmer Right for Your Pool? Key Considerations
Before deciding if a low suction pool skimmer is right for you, consider the following factors:
- Local Regulations: Check your local building codes and safety regulations to see if low suction skimmers or SVRS systems are required or recommended.
- Presence of Children or Vulnerable Individuals: If you have children, elderly individuals, or anyone with limited mobility using the pool, a low suction skimmer is highly recommended.
- Type of Pool Pump: If you have a variable speed pump, a low suction skimmer can be a great complement, allowing for more efficient and safer operation.
- Amount of Debris: Assess the typical amount of debris that enters your pool. If you frequently have large amounts of leaves or other debris, you may need to skim the pool more often with a low suction skimmer.
- Budget: Factor in the initial cost of the skimmer and any associated installation costs. However, also consider the potential long-term savings from reduced pump strain and energy efficiency.
Choosing a Low Suction Pool Skimmer: Features to Look For
When selecting a low suction pool skimmer, consider the following features:
- Skimmer Basket Size: A larger basket will require less frequent emptying.
- Adjustable Weir: An adjustable weir helps to optimize water flow and debris collection.
- Durable Construction: Look for skimmers made from high-quality, UV-resistant materials.
- Ease of Installation: Consider the ease of installation, especially if you plan to install it yourself.
- Compatibility with your Pool Type: Ensure the skimmer is compatible with your pool’s construction (inground, above ground, etc.).
Low Suction Pool Skimmer: Installation Tips
While professional installation is often recommended, here are some general tips if you plan to install a low suction pool skimmer yourself:
- Turn off the Pool Pump: Before starting any work, ensure the pool pump is completely turned off.
- Follow Manufacturer’s Instructions: Carefully read and follow the manufacturer’s instructions for proper installation.
- Seal Connections: Use appropriate sealants to ensure watertight connections and prevent leaks.
- Test the System: After installation, test the skimmer to ensure it is functioning correctly and that there are no leaks.
Low Suction Pool Skimmer FAQs
Here are some frequently asked questions to help you decide if a low suction pool skimmer is the right choice for your pool.
What exactly is a low suction pool skimmer?
A low suction pool skimmer is a type of skimmer designed to reduce the powerful suction found in traditional pool skimmers. This makes it safer for swimmers, especially children, who might accidentally get too close. It achieves this by either distributing the suction across a wider area or by mechanically limiting the flow.
How does a low suction pool skimmer improve safety?
By reducing the suction force, a low suction pool skimmer minimizes the risk of entrapment. Standard skimmers can create a strong vacuum, potentially trapping body parts against the skimmer opening. The lower suction makes it easier for someone to free themselves if they get too close.
Are there any drawbacks to using a low suction pool skimmer?
A potential drawback is that a low suction pool skimmer might not remove debris as quickly or efficiently as a high-suction model. However, regular pool maintenance and proper skimming habits can easily compensate for this. The safety benefits usually outweigh this minor inconvenience.
Is a low suction pool skimmer difficult to install?
Installation complexity depends on the specific model and your existing pool setup. In many cases, it’s a straightforward replacement for your current skimmer. Always refer to the manufacturer’s instructions, and consider professional installation if you’re unsure. Ensure any installed low suction pool skimmer meets local safety regulations.
So, what’s the verdict? Deciding if a low suction pool skimmer is right for your setup really depends on understanding your pool’s specific needs. Hopefully, this article helped shed some light on making that decision. Happy swimming!
