Why Is My Pool Filter Making Bubbles?


If you notice bubbles forming in your pool filter system, you may wonder if this is normal or if it indicates a problem. While some bubble formation is typical during filtration and backwashing, excessive or persistent bubbles could be a sign of various issues that affect the efficiency and longevity of your pool equipment, as well as the quality of your pool water. In this article, we will explain the reasons why your pool filter may be making bubbles, what you can do to prevent or fix the problem, and when you should seek professional help.


1. Air infiltration


One of the most common causes of bubbles in a pool filter system is air infiltration, which means that air is leaking into the system and getting trapped inside. This can happen in several ways, such as a loose or cracked fitting, a faulty o-ring or gasket, a worn or torn valve or clamp, or a damaged or clogged suction line. When air enters the system, it creates pockets or bubbles that reduce the flow of water and increase the pressure inside the filter, leading to less effective cleaning and possible damage to the pump or motor. Air infiltration can also cause the pool to lose water or create noisy or erratic behavior of the equipment.


To diagnose air infiltration, you can inspect the system for visible leaks or signs of wear and tear, such as rust, corrosion, or discoloration. You can also try to pressurize the system with a handheld air pump or water pressure gauge and observe if any air bubbles appear in the water or at the joints or valves. To fix air infiltration, you should first turn off the power to the pump and bleed the air from the system by opening the vent or air relief valve on the filter tank. Then, you should tighten or seal any loose or damaged components or replace them if necessary. If the suction line is clogged or cracked, you may need to use a pipe snake or hire a professional plumber to clean or replace it.


2. Chemical imbalance


Another cause of bubbles in a pool filter system is a chemical imbalance in the pool water, which can affect the pH, alkalinity, or calcium hardness levels. If the water is too acidic or too alkaline, it can cause corrosion or scaling on the pool equipment, including the filter, and create small bubbles that cling to the filter media or elements. If the water is too hard or too soft, it can also cause cloudy or foamy water that can clog the filter or reduce its effectiveness. To avoid a chemical imbalance, you should test the water regularly with a pool test kit or strips and adjust the levels accordingly by adding or reducing chemicals or using a water conditioner. You should also avoid overusing chemicals or shocking the pool excessively, as this can create bubbles or foam that may damage the filter.


3. Oversized pump


A third cause of bubbles in a pool filter system is an oversized pump, which means that the pump is too powerful for the filter and creates a turbulence or cavitation effect that generates bubbles. This can happen when you replace the original pump with a stronger one or when you upgrade the filter without adjusting the pump accordingly. An oversized pump not only wastes energy and increases your electricity bill, but also puts undue stress on the filter and shortens its lifespan. To solve this problem, you should consult a pool professional who can recommend the right size and type of pump for your filter and pool configuration and install it properly.


4. Dirty or worn out filter media


A fourth cause of bubbles in a pool filter system is dirty or worn out filter media, which can accumulate debris, particles, or algae that create bubbles, foam, or a higher pressure and flow resistance in the system. If the filter media is not washed or backwashed regularly or is not replaced periodically, it can also lose its filtering capacity and allow fine particles to pass through, leading to cloudy or green water. To prevent this, you should follow the manufacturer's instructions for cleaning and maintaining the filter media and replace it as recommended.


5. Structural damage


A fifth cause of bubbles in a pool filter system is structural damage to the filter tank or housing, which can result from freezing, cracking, or impact. If the filter tank or housing is not properly supported or installed, or if it is exposed to extreme temperatures or pressure, it can weaken or deform and allow air or water to escape or enter through the cracks or holes. To check for structural damage, you can inspect the tank or housing for any signs of cracks, dents, or deformations and listen for any unusual noises when the pump is running. To fix structural damage, you may need to replace the entire filter or contact a qualified repair technician.


In conclusion, bubbles in a pool filter system can indicate various problems that require different solutions. By identifying the cause of the bubbles and addressing it promptly and effectively, you can ensure that your pool remains clean, clear, and safe to swim in. Remember to follow the recommended maintenance and safety procedures and seek professional help when needed.
