Why Is My Pool Filter Blowing Out Dirt?
Maintaining a pool can be quite overwhelming, especially when you have to deal with issues like a pool filter blowing out dirt. A swimming pool filter is an essential component that helps keep your pool water clean and clear. If you notice that your pool filter is throwing out dirt, it could be a sign of an underlying problem. In this article, we will be discussing some of the reasons why your pool filter is blowing out dirt, and what you can do to fix it.
Causes of Pool Filter Blowing Out Dirt
Clogged Filter Cartridge
One of the most common reasons your pool filter is blowing out dirt is a clogged filter cartridge. Over time, debris and contaminants can accumulate in the filter cartridge, preventing it from effectively filtering out dirt and impurities. If you notice that your pool filter is throwing out dirt, you should check the cartridge, and if it is clogged, it may need a thorough cleaning or replacement.
Poor Water Chemistry
Another reason your pool filter may be blowing out dirt is poor water chemistry. If your pool water chemistry is not balanced, it can cause your filter to work harder, leading to a buildup of dirt and contaminants. An imbalanced pool pH, alkalinity, or high levels of calcium can cause issues with pool filters. Ensure you maintain proper water chemistry levels to prevent these issues.
Overuse of Pool Chemicals
Overusing pool chemicals can also lead to a pool filter blowing out dirt. Excess chemicals such as chlorine, algaecides, and clarifiers can lead to overloading of the filter, making it work harder than it should. It's important to follow manufacturer instructions for pool chemical usage, and avoid using more chemicals than necessary.
Miscalibrated Filter Valves
A miscalibrated pool filter valve can also be the cause of your pool filter blowing out dirt. Valves that are not correctly aligned can divert dirty water back to the pool, leading to unfiltered dirt and debris. Regularly inspecting and cleaning pool filter valves can prevent this issue.
Incorrect Filter Size
Using an incorrect filter size can also cause your pool filter to blow dirt. If the filter size is too small for your pool, it may not be able to handle the amount of debris and dirt being removed from the water. As a result, it can get clogged up easily and blow out dirt. Ensure you select the correct filter size for your pool and its needs.
What To Do If Your Pool Filter Is Blowing Out Dirt
Clean or Replace the Filter Cartridge
If your pool filter is blowing out dirt due to a clogged filter cartridge, you can clean or replace the cartridge. A thorough cleaning will involve removing the filter and soaking it in a cleaning solution to get rid of any debris and contaminants clogging it. However, if the filter is too old and worn, replacing it with a new one may be the best solution.
Balance Your Pool Water Chemistry
If poor water chemistry is causing your pool filter to blow out dirt, it is essential to balance the water chemistry by adjusting pH, alkalinity, and calcium levels. You can test the chemical levels using a pool test kit or have a professional do it for you.
Avoid Overusing Pool Chemicals
To avoid overloading your pool filter, you should follow manufacturer instructions for pool chemical usage. Try to avoid using more chemicals than necessary.
Inspect and Calibrate Pool Filter Valves
Ensure your pool filter valves are correctly aligned and calibrated to prevent the diversion of unfiltered water back to the pool. You may need to clean or replace faulty valves.
Use The Correct Filter Size
Choosing the right filter size is essential for proper filtration. Ensure you select the correct filter size for your pool and its needs, to avoid clogging and blowing out dirt.
In conclusion, a pool filter blowing out dirt can be an indication of an underlying issue that needs to be addressed. By understanding the reasons why your pool filter is blowing out dirt, you can take the necessary steps to fix the problem and keep your pool water clean and clear. Regular cleaning and maintenance of your filter, proper water chemistry, and careful use of pool chemicals can go a long way in preventing issues with your pool filter..
