How to Repair a Pool Skimmer That’s Not Working Properly
A pool skimmer is a critical component of your swimming pool’s filtration system. It removes debris, leaves, and contaminants from the water before they sink to the bottom. When it stops working correctly, your pool can quickly become a breeding ground for algae, bacteria, and unwanted debris. If you’ve noticed issues with your skimmer, don’t panic. With the right approach, you can diagnose and repair the problem before it worsens.
Identifying the Symptoms of a Faulty Pool Skimmer
Before attempting any repairs, it’s essential to determine whether your skimmer is indeed malfunctioning. Here are common signs of a failing skimmer:
- Weak Water Circulation: Stagnant water or weak suction around the skimmer suggests inefficiency.
- Excess Floating Debris: Leaves and debris accumulating on the water surface instead of being drawn into the skimmer basket indicate poor function.
- Air Bubbles in the Pump Basket: Air entering the pool’s circulation system can disrupt efficiency and may point to a leak in the skimmer line.
- Low Water Levels in the Skimmer Basket: A skimmer that isn’t pulling water effectively may have a blockage or leak.
- No Suction at the Skimmer Opening: A clogged skimmer, closed valve, or pump issue could be the cause.
Once you’ve identified the symptoms, it’s time to troubleshoot and resolve the problem.
Removing Clogs and Blockages in the Skimmer System
A common reason for skimmer failure is a blockage in the skimmer line, basket, or plumbing.
Cleaning the Skimmer Basket
The skimmer basket captures debris before it reaches the pool pump. If it’s full, water flow can be obstructed.
- Remove the skimmer lid and pull out the basket.
- Empty the debris and rinse the basket with a hose.
- Check for cracks that might allow large debris to pass through.
- Reinsert the basket and test the skimmer’s suction.
Unclogging the Skimmer Line
If the skimmer basket is clean but suction remains weak, the skimmer line might be blocked.
- Turn off the pool pump.
- Use a garden hose or a plumber’s snake to flush out any obstructions in the skimmer pipe.
- Alternatively, use a skimmer vacuum plate to create suction and dislodge the clog.
- Restart the pump and check if the suction improves.
Detecting and Repairing Leaks in the Skimmer System
Leaks in your skimmer system can allow air to enter the circulation system, reducing efficiency.
Checking the Skimmer Mouth and Housing
Cracks in the skimmer housing can lead to leaks and reduced suction.
- Turn off the pump and inspect the skimmer for visible cracks.
- If cracks are found, use a pool-safe epoxy or underwater sealant to patch them.
Performing a Dye Test for Hidden Leaks
For less obvious leaks, a dye test can help locate them.
- Fill a squeeze bottle with food colouring.
- Slowly release the dye around the skimmer and observe if it is drawn into a crack.
- If a leak is detected, patch it with underwater sealant.
Maintaining the Correct Water Level for Optimal Skimmer Performance
Your pool’s water level plays a vital role in skimmer function. If the level is too low, air can enter the system, leading to inefficiencies in the pump.
Adjusting Water Levels
- The water level should ideally be around halfway up the skimmer opening.
- If the level is too low, add water using a garden hose.
- If the level is too high, use a submersible pump or pool vacuum to remove excess water.
Optimising Skimmer Valve Settings for Better Performance
If your pool has multiple skimmers, you may need to adjust the skimmer valve to achieve optimal suction.
Locating and Adjusting the Skimmer Valve
- Find the skimmer control valve near the pump.
- If the valve is partially closed, open it to allow full water flow.
- If you have multiple skimmers, balance the valves to distribute suction evenly.
Ensuring the Pool Pump and Filter System Are Functioning Properly
A malfunctioning pool pump or dirty filter can reduce skimmer efficiency.
Inspecting the Pool Pump Basket
- Turn off the pump and remove the pump lid.
- Empty debris from the pump basket and rinse it thoroughly.
- Reinsert the basket and restart the pump.
Cleaning or Replacing the Pool Filter
- If you have a sand or DE filter, backwash it to remove trapped debris.
- If you have a cartridge filter, remove it and rinse it thoroughly or replace it if too dirty.
Replacing a Faulty Skimmer Weir to Improve Functionality
The skimmer weir (flap) helps regulate water flow into the skimmer. If it’s broken or missing, the skimmer won’t function correctly.
Steps to Replace a Skimmer Weir
- Turn off the pool pump.
- Remove the damaged skimmer weir.
- Insert a new weir, ensuring it swings freely.
- Turn the pump back on and test for proper function.
Seeking Professional Help for Persistent Skimmer Issues
