Caring For Your Pool Filters When Out Of Use

Tips on when to replace cartridges & filters on your 3M reusable respirator

Another thing to consider is what happens to your filters when the pool isnt in use. If you use your small swimming pool seasonally, ensure your cartridge filters are being stored correctly when out of season. Also, check them before the next season begins, as they can sometimes lose their quality over time even when not in use.

Pump filter systems should still run during the off-season every so often to keep the chemicals in the water ticking over. Therefore, you need to monitor your filters during the off-season. As with your pool as a whole, investing in a cover and properly closing your pool will also help keep your filters working efficiently.

DE filters should be cleaned with special products at least once every season. Perform a complete cleaning and inspection yearly.

Check the pressure gauge to figure out when its time to backwash the more debris is in your filter, the higher the pressure will be.

If you have a cartridge filter, clean it weekly, monthly, or less frequently depending on its size and how often youre using the pool. These types of filters dont require backwashing, but you need to disassemble them every time they need cleaning.

If your pool filters pressure gauge has a high PSI reading even after giving the pool cartridge filter a good cleaning, this means that the fibers have already permanently been clogged up. This is another sure sign that you will need to replace the filter.

    Which Cartridges Should Be Replaced And How Often

    Commonly a reverse osmosis system actually has more than one filter and process. For instance, our 5-stage reverse osmosis water filter system has the following filters:

  • Sediment pre-filter
  • Prolonged contact time filter
  • Carbon polishing post filter
  • Each one has a specified purpose. The sediment pre-filter takes care of the dust and debris . The GAC filter removes the chlorine. The third filter is where most contaminants are removed. The PCT filter removes fine dust. Finally, the carbon polishing post filter ensures that the resulting water has a fresh taste.

    Every 12 months all the filters except the RO membrane might need to be replaced. Take note that filters dont allow contaminants to pass through. These objects and substances may eventually accumulate and make the filters far from effective.

    Minerals may accumulate and clog the pores of the filters. The activated carbon filter might also eventually lose its ability to adsorb chlorine and other particles. To maintain the effectiveness of a filtration system, its ideal to replace the filters regularly.

    When To Clean A Pool Filter Cartridge

    Filter cartridges should be cleaned whenever the filter pressure gauge increases by about 8 PSI or more above the normal operating pressure, or at least every 6 months assuming your filter is properly sized and you havent had any unusually large burden placed on the filter .

    Your Pool’s Filter Cartridge: When To Clean And When To Replace

    A well kept cartridge filter lays at the heart of beautiful swimming pools all across Miami and the world. While this might be the most exciting part of yourpool maintenance routine, having a properly kept cartridge filter not only keeps your pool sparkling clean, but it also extends the lifespan of your pool pump, and pool equipment. As pool owners it is important to know how often you should clean your cartridge filter and when its time to switch it out for a new one.

    The golden rule for single cartridge filter cleaning is once a month. Remember to keep in mind that this rule does not apply to every swimming pool. EVERY POOL IS DIFFERENT. Your frequency of cleaning should depend on the size of your pool, the size of your cartridge filter, pool chemistry, your bather load and the amount of dirt on debris that falls in your pool. Many pools that have undersized filters may need to be cleaned more often, while pools with oversized filter might be able to wait 2-3 months between cleanings.

    When you take your cartridge out many times you will be able to visually see the accumulation of dirt and oils on your filter media. This change in color is a good indication that it is time to wash down your cartridge. Another way to monitor your filter cartridge is by checking the pressure gauge. If the filter pressure increases by about 8-10 PSI or more above the normal operating pressure

    Here Are Some Tips To Know When Its Time To Change Your Pool Cartridge Filter:

    Most pool owners replace their filter cartridges about every 2-3 years. But, remember the time frame of your filter may be longer or shorter depending on the demand.

    • PSI is high

    High-pressure reading is a sign of increasing tension or the pressure within the filter. A common cause of a high PSI reading is a dirty cartridge. Always make sure to keep in clean so it can last longer.

    • End caps cracked

    Once the end cap begins to crack it is better to replace the cartridge filter right away. Using a cartridge with a broken cap can cause the filter system damage. Because the broken piece might circulate through the filter system and can cause damage.

    • Cloudy water

    Another way to check if your filter needs a replacement is when you notice that the pool water stays cloudy. Despite the proper chemical balance, it stays cloudy or green. And that is the time you need to change your cartridge filter.

    You can also try to clean the cartridge first, but if the problem does not clear up in a few days then its better to replace it. It means that the cartridge is unable to filter the water as effectively as before. It is time to buy a new cartridge filter.

    • Wear fabric

    Made from porous materials, the pool cartridge filter allows the water through while blocking debris to your pool water. But wear and tear from the water pressure and debris can cause the material to unravel.
