Maintaining proper pool functionality requires attention to every component, and one often overlooked but crucial element is the skimmer basket. Designed to catch large debris before it reaches the pump, the skimmer basket can sometimes become a nuisance when it floats out of position. This issue not only disrupts the skimming process but can also affect the overall circulation and cleanliness of the pool. In this article, we will discuss the reasons why a skimmer basket may float and explore a variety of practical, effective solutions to keep it securely in place.
Understanding the Role of the Skimmer Basket
Before diving into the “why” and “how” of skimmer basket displacement, it’s essential to understand its role. Located inside the skimmer box—usually mounted on the pool wall—the skimmer basket acts as the first line of defense against leaves, twigs, insects, and other large debris that might otherwise clog or damage the pool pump and filter.
Importance of Proper Skimmer Basket Function
When functioning correctly, a skimmer basket optimizes water filtration by:
- Preventing debris from entering the pump
- Reducing strain on the filter system
- Improving overall water circulation
- Helping remove surface contaminants efficiently
Proper positioning is key—this is where problems arise when the basket begins to float.
Why Does a Skimmer Basket Float?
Floating occurs when the basket loses its proper seating within the skimmer, either partially or fully rising out of its intended position. Several factors can cause this behavior:
Common Causes of Skimmer Basket Floating
- Improper sealing: If the skimmer lid isn’t sealed correctly, pressure changes within the system can push the basket upward.
- Air entrapment: Air bubbles getting trapped inside the skimmer box or basket can make it buoyant, lifting it during operation.
- Water flow imbalance: A sudden increase in water flow or turbulence from the return jets can displace the basket.
- Worn-out parts: Over time, clips or seats that secure the basket may deteriorate, reducing grip.
- Loose basket lid or cover: A lid that isn’t fully closed allows air to build up beneath the basket.
Identifying the root cause is key to choosing the right solution.
Signs You Have a Floating Skimmer Basket
If your skimmer basket is floating, you may observe:
- Water bypassing the basket entirely
- Increased debris accumulation in the pump basket
- Visible upward movement of the basket when the pump is running
- Reduced skimming efficiency, leading to more manual cleaning
Now that we’ve outlined why a skimmer basket might float, let’s explore effective ways to prevent this from happening.
Solutions to Keep the Skimmer Basket from Floating
Several practical and innovative techniques can be used to secure your skimmer basket. These methods vary in complexity and materials required, allowing pool owners to choose the best approach based on their equipment and comfort level.
1. Use a Skimmer Weight
One of the most straightforward and popular solutions is to use a dedicated skimmer basket weight. These accessories are specifically designed to press down on the basket to prevent it from rising.
How Skimmer Weights Work
Most skimmer weights are made from plastic or metal and contain a small ballast, often filled with sand or lead. They are placed on top of the skimmer basket and help provide enough pressure to keep it in place during operations.
Types of Skimmer Weights
| Type | Material | Pros | Cons |
|---|---|---|---|
| Plastic Skimmer Weight | Durable plastic with ballast insert | Corrosion-resistant, affordable | Less weight capacity |
| Metal Skimmer Weight | Coated steel or lead | Heavier, provides more pressure | May corrode over time |
These weights are ideal for most standard above-ground and in-ground pools.
2. Modify the Skimmer Lid or Cover
Sometimes simply ensuring the skimmer lid remains securely fastened can help a great deal. Over time, lids may become worn or improperly sealed, allowing air buildup that lifts the basket.
Steps to Improve Skimmer Lid Function
- Check the lid o-ring: A damaged or dry o-ring can cause air leaks. Lubricate or replace it if necessary.
- Secure with a lid lock: Some lids have a locking mechanism; ensure it is fully engaged.
- Upgrade the lid: Consider replacing older plastic lids with heavier, more secure models.
Even minor adjustments can have a major impact on keeping the basket grounded.
3. Install a Skimmer Liner or Baffle
A less common but effective method involves using a skimmer liner or baffle, which helps regulate water flow and air pressure inside the skimmer box.
How a Skimmer Liner Helps
By creating a smoother water path into the skimmer, liners reduce turbulence and minimize the chance of lifting the basket. Baffles inside the skimmer box can help direct water downward instead of allowing it to swirl up and push against the basket.
Installation Tips:
- Measure your skimmer dimensions carefully before ordering a liner.
- Install the liner so that water flows into the box and goes directly into the basket.
- Avoid overcrowding the skimmer with unnecessary accessories.
This solution is particularly effective in preventing air entrapment from the start.
4. Use Pool Ball or Golf Ball Technique
This is a budget-friendly solution many pool maintenance professionals swear by. Placing a pool ball or a golf ball on top of the basket can provide the necessary weight to keep it from rising.
Why It Works
- The ball’s curved surface allows easy access for basket removal while still applying pressure.
- It prevents air bubbles from getting trapped below the basket, which is a common cause of floating.
- Easy to install and works effectively for many skimmer types.
How to Use Pool Balls
- Clean the skimmer basket thoroughly.
- Place a clean pool or golf ball on top.
- Replace the skimmer lid securely.
This method works best in skimmers with tight-fitting lids or baskets designed to accommodate floating objects.
5. Adjust Pump Suction and Flow
Surprisingly, the way your pool pump and return system works can directly influence the behavior of the skimmer basket. If water return is directed toward the skimmer, the resulting turbulence can push the basket upward.
How to Optimize Water Flow
- Adjust return jets: Point them downward or away from the skimmer for optimal flow.
- Balance suction valves: If your system has a main drain and skimmer suction, ensure they are balanced to avoid excessive lift.
- Check for suction leaks: Leaks in the skimmer line can cause vacuum pressure to destabilize the basket.
Skimline Air Relief Valves
Consider installing a small air relief valve on the skimmer line. These valves help control air pressure buildup that could otherwise lift the basket. An automatic system can be especially useful for larger or commercial pools.
6. Replacing Faulty or Old Skimmer Baskets
If none of the methods above seem to work, the problem may lie within the basket itself. Some older or damaged models are more prone to floating due to design defects, wear and tear, or improper fit.
Signs It’s Time for a Replacement
- Visible cracks or misshapen sides
- Missing or worn basket clips
- Consistent floating despite weight additions
- An improper fit in the skimmer housing
When replacing your skimmer basket, consider these models known for superior fit and performance:
| Model | Features | Compatibility |
|---|---|---|
| Zodiac G410082 Skimmer Basket | Heavy-duty construction, reinforced edges | Universal fit for most in-ground pools |
| Pentair 355310 Skimmer Basket | Stable base, pressure-balanced design | Designed for Pentair equipment |
| Hayward SP0714T Skimmer Basket | Secure fit, durable polypropylene material | Hayward model compatibility |
Purchasing a high-quality basket can significantly reduce floating and improve debris capture.
Troubleshooting Floating Skimmer Issues
Sometimes, floating skimmer baskets seem resistant to even tried-and-true solutions. Here are a few additional considerations that may help you resolve the issue:
Check the Water Level
Improper water levels can hinder skimmer function. Too high, and water flows over the weir without proper suction; too low, and air gets pulled into the skimmer basket. Aim to keep the water level between one-third to halfway up the skimmer opening.
Inspect the Weir Door
The weir door is the small flap at the front of the skimmer intended to control water input. If the weir door is stuck open or broken, it can cause erratic water flow that interferes with the basket’s position.
Verify System Start-Up Procedure
At the start of each pool season, improper priming of the pump or system can set off pressure imbalances within the skimmer. Always prime the pump thoroughly and release air via the pressure valve before starting the pool system after winterization or maintenance.
Consider Professional Inspection
If your floating skimmer basket is a persistent problem, especially after trying multiple solutions, it may indicate a deeper issue with the skimmer design, plumbing configuration, or pump system. In such cases, it’s wise to consult a professional pool technician for a full diagnosis.
Preventive Maintenance: Keeping Skimmer Baskets Secure Long-Term
Regular maintenance plays a vital role in ensuring your skimmer basket—and the entire filtration system—functions properly.
Monthly Maintenance Checklist
- Clean the skimmer basket thoroughly.
- Check and replace damaged clips or o-rings.
- Ensure the water level is correct.
- Adjust return jets to minimize turbulence.
- Verify skimmer basket weight or stabilization method is functioning.
By following a consistent preventive schedule, you can avoid both floating baskets and more serious filtration issues.

Why does my skimmer basket keep floating?
There are several reasons why a skimmer basket might float, with the most common being improper installation or poor design compatibility. When a skimmer basket isn’t secured correctly or doesn’t sit snugly within the skimmer throat, water flow can push it upward, causing it to rise out of position. Additionally, if your pool experiences high water flow or turbulence due to the pump’s power or incorrect jet positioning, it can further contribute to the basket floating.
Another contributing factor may be the type of basket you are using. Some skimmer baskets are made from lighter materials that are more buoyant, especially when filled with air or debris. If the basket lacks sufficient weight or the necessary slots and tabs to anchor it properly, it’s more likely to become dislodged. A clogged or overly full basket can also trap air, increasing buoyancy and making the basket rise. Identifying the exact cause is essential for implementing the correct solution.
How can I secure a skimmer basket to prevent it from floating?
One of the easiest and most effective ways to secure a skimmer basket is by using a skimmer weight or a basket stabilizer. These accessories are specifically designed to keep the basket anchored at the bottom of the skimmer, preventing it from rising with water flow. Weights are typically made of metal or heavy-duty plastic and can be clipped onto the basket or placed inside to add downward force without interfering with debris collection.
Alternatively, installing a skimmer basket with built-in slots or a locking mechanism can also help. Some models feature clips or tabs that engage with the skimmer housing to hold the basket in place. Making sure the basket fits properly inside the skimmer and that the skimmer lid is correctly seated can also reduce unnecessary turbulence. By combining physical weights and structural design features, you can significantly reduce or eliminate basket floatation.
Can using a skimmer lid affect the floating issue?
Yes, the skimmer lid can play a role in whether or not your basket floats. A properly fitted lid helps maintain smooth water flow into the skimmer and reduces turbulence that might lift the basket. If the lid is cracked, poorly seated, or completely missing, the unregulated flow can cause uneven pressure around the basket, contributing to its buoyancy.
Another aspect is the venturi effect, which occurs when water rushes past the skimmer lid and creates suction that might displace the basket. A well-functioning skimmer lid helps balance the flow and pressure, ensuring the basket remains stable. If you’re experiencing floating issues, consider replacing an old or damaged lid and ensure it fits securely. Upgrading to a high-quality lid that enhances the flow dynamics may also provide added stability.
What type of skimmer baskets are less likely to float?
Skimmer baskets specifically designed to resist buoyancy are typically made with heavier materials such as sturdy plastic or those that incorporate built-in weights. These baskets are engineered to stay submerged despite the upward pressure from water flow. Some high-quality models also feature strategically placed slots and drainage holes that allow water to pass through evenly, minimizing floatation.
Additionally, baskets with interlocking or clip-in designs offer more stability by locking into the skimmer housing. These mechanisms anchor the basket in place and prevent it from rising, even in powerful systems. Brands like AquaStar, Pentair, and Hayward manufacture skimmer baskets optimized for stability. Choosing the right type of basket based on material, weight distribution, and installation method can be a decisive factor in resolving floating issues without additional modifications.
Should I adjust the pool pump or water flow to prevent basket floatation?
Adjusting the pump’s speed or water flow can be a useful troubleshooting method to reduce basket buoyancy. If your pump is too powerful for the system, it may generate strong suction and turbulence that lifts the basket. Reducing the pump speed (especially if you have a variable-speed model) can help balance the flow and decrease the upward force on the basket.
However, it’s important not to compromise filtration efficiency. A pump set too low might not circulate water effectively, leading to poor cleaning performance and potential water clarity issues. You should test and find the optimal flow rate that keeps the basket stable while maintaining adequate circulation. Additionally, adjusting the return jets away from the skimmer area can reduce direct pressure on the basket, preventing it from floating due to turbulent water movement.
Are there DIY methods to keep a skimmer basket from floating?
Many pool owners successfully use DIY methods to prevent skimmer basket floatation, such as attaching a small weight to the basket. A sealed container filled with sand, a bolt, or even a small section of PVC pipe can be clipped or tied to the basket to add downward force without impeding functionality. It’s important that the weight is corrosion-resistant and completely sealed to avoid contamination or clogging the system.
Another creative option involves modifying the basket with clips, zip ties, or tabs that secure it to the skimmer housing. For example, some users drill small holes in the sides of the basket and thread a zip tie through the skimmer slot to hold it in place. These methods are cost-effective and quick to implement, but ensure that any modifications don’t obstruct water intake or damage the basket. With a bit of ingenuity, DIY fixes can be both durable and effective.
When should I consider professional help for a floating skimmer basket issue?
If you’ve tried multiple methods—such as using weights, replacing the basket, adjusting the pump flow, and modifying the skimmer lid—without success, it may be time to consult a professional. A licensed pool technician can assess your entire filtration system to identify whether underlying issues, such as incorrect plumbing or pump sizing, are contributing to the basket’s buoyancy.
Additionally, if your pool equipment is old or worn, a technician might recommend upgrading certain components for better compatibility. Persistent skimmer basket issues could also indicate a larger imbalance in your pool’s hydraulics or circulation system. Professional guidance ensures not only that the basket problem is resolved, but also that your pool operates efficiently and safely. Consulting an expert can save time, prevent further damage, and provide long-term solutions tailored to your pool setup.
