Pool Skimmer Not Working? Here’s Why It’s Not Pulling Water and How to Fix It
A well-functioning pool skimmer is essential for keeping your pool clean and clear. It removes debris like leaves, bugs, and dirt from the water’s surface, ensuring your pool stays inviting. However, when your pool skimmer stops pulling water, it can lead to murky water and a less enjoyable swimming experience. If you’re facing this issue, you’re not alone. Many pool owners encounter this problem, but the good news is that it’s often fixable with some troubleshooting. At Think Different Network, we’re here to guide you through the reasons your pool skimmer isn’t working and how to resolve it quickly.
Understanding the Role of a Pool Skimmer
A pool skimmer acts like a vacuum, pulling water and debris into a basket for easy removal. It’s a critical part of your pool’s circulation system, working alongside the pump and filter to maintain water clarity. When the skimmer stops pulling water, debris accumulates, and water quality suffers. Identifying the cause is the first step to restoring your pool’s cleanliness.

Common Reasons Your Pool Skimmer Isn’t Pulling Water
Several issues can cause a pool skimmer to stop functioning properly. Below, we explore the most common culprits and how to diagnose them.
Clogged Skimmer Basket
A clogged skimmer basket is one of the most frequent reasons for reduced suction. Leaves, twigs, and other debris can fill the basket, blocking water flow. When this happens, the skimmer can’t pull water effectively, and the pump may struggle.
To check for this issue, turn off the pool pump for safety. Remove the skimmer lid and inspect the basket. If it’s full, empty the debris and rinse the basket with a garden hose. Regularly cleaning the basket prevents clogs and ensures consistent skimmer performance.
Low Water Levels
If your pool’s water level is too low, the skimmer may not be able to pull water. Ideally, the water should be halfway up the skimmer opening. When levels drop below this point, the skimmer sucks in air instead of water, reducing suction.
Check your pool’s water level and top it up if necessary. According to Pool & Spa News, maintaining proper water levels is crucial for efficient pool circulation. Use a garden hose to fill the pool to the recommended level, then test the skimmer.
Air Leaks in the System
Air leaks in the suction line or skimmer can disrupt water flow. Common sources include loose fittings, cracked pipes, or a damaged skimmer lid. Air in the system reduces suction, causing the skimmer to underperform.
Inspect the skimmer lid and O-rings for cracks or wear. Tighten any loose connections and replace damaged components. If you suspect a leak in the suction line, you may need a professional to locate and fix it.
Blocked or Damaged Impeller
The impeller, a rotating component in the pool pump, creates the suction that pulls water through the skimmer. If it’s clogged with debris or damaged, the skimmer won’t function properly. Hair, leaves, or small objects can jam the impeller, reducing its efficiency.
To check the impeller, turn off the pump and remove the pump housing. Clear any debris and inspect the impeller for damage. If it’s worn or broken, consider replacing it or consulting a professional for repairs.
Weir Door Issues
The weir door, a flap inside the skimmer, regulates water flow and traps debris. If it’s stuck, broken, or missing, the skimmer may not pull water effectively. A stuck weir door can block water from entering the skimmer, while a broken one may allow debris to escape.
Inspect the weir door for movement. It should float and move freely with the water. If it’s stuck, clean around it to remove debris. Replace a broken weir door to restore proper function.
Step-by-Step Guide to Fixing a Pool Skimmer Not Pulling Water
Once you’ve identified the issue, follow these steps to fix your skimmer. Always prioritize safety by turning off the pool pump before starting any repairs.
- Check the Skimmer Basket: Remove and clean the basket. Ensure no debris is blocking the skimmer’s opening.
- Verify Water Levels: Adjust the pool’s water level to halfway up the skimmer opening.
- Inspect for Air Leaks: Check the skimmer lid, O-rings, and suction lines for leaks. Tighten or replace parts as needed.
- Examine the Impeller: Clear any debris from the pump’s impeller and check for damage.
- Test the Weir Door: Ensure the weir door moves freely. Clean or replace it if necessary.
- Run the System: Turn the pump back on and observe the skimmer. If it’s still not pulling water, consider consulting a pool professional.
Regular maintenance can prevent many of these issues. For example, The Spruce recommends cleaning your skimmer basket weekly and checking water levels regularly to avoid problems.
When to Call a Professional
While many skimmer issues are fixable at home, some require professional expertise. If you’ve checked the basket, water levels, and impeller but the skimmer still isn’t pulling water, there may be a more complex issue, such as a major air leak or pump failure. A pool technician can diagnose and repair problems like damaged pipes or faulty pumps, saving you time and ensuring your pool stays in top shape.
Preventive Maintenance Tips
To keep your pool skimmer working smoothly, incorporate these maintenance habits:
- Clean the Skimmer Basket Weekly: Remove debris to maintain strong suction.
- Monitor Water Levels: Keep the water halfway up the skimmer opening.
- Inspect Equipment Regularly: Check for leaks, cracks, or wear in the skimmer and pump.
- Schedule Annual Pool Maintenance: A professional tune-up can catch issues early.
By staying proactive, you can avoid most skimmer problems and keep your pool clean and inviting.

Frequently Asked Questions
Why is my pool skimmer not pulling water even after cleaning the basket?
If the basket is clean, check the water level, impeller, or weir door. Low water or a clogged impeller can reduce suction. Air leaks may also be the cause.
How often should I clean my pool skimmer basket?
Clean the skimmer basket weekly to prevent clogs and maintain strong suction. During heavy debris seasons, check it more frequently.
Can low water levels damage my pool pump?
Yes, low water levels can cause the pump to suck in air, leading to overheating or damage. Keep the water halfway up the skimmer opening.
How do I know if my pool pump impeller is clogged?
If the skimmer isn’t pulling water, turn off the pump and check the impeller for debris. A clogged impeller reduces suction and water flow.
When should I replace my pool skimmer’s weir door?
Replace the weir door if it’s stuck, broken, or missing. A faulty weir door prevents the skimmer from trapping debris effectively.
