To ensure optimal performance, all swimming pool components—such as the filter, pump, and chlorinator—need to stay in top condition. Despite your best maintenance efforts, you might notice that the pool water is starting to lose its clarity and sparkle. This could be a sign that the pool’s filtration system needs attention or possibly a replacement. Here are a few indicators that it might be time to change your swimming pool filter.
1. Filter Remains Dirty Even After Cleaning
Like filters in air purifiers or vacuum cleaners, pool filters also become stained over time. When cartridge filters in particular no longer appear clean even after repeated spraying with a hose, it may indicate that the filter is no longer effective. If the filter remains dark and dirty despite thorough cleaning, it could be a sign that a replacement is necessary.
2. Cracked or Broken Plastic Components
Small, circular plastic structures on top of pool filters allow unfiltered water to pass through for filtration. Any cracks or breaks in these structures can lead to hygiene issues as unfiltered water may bypass the filtration process. If you notice any damage here, it’s best to replace the affected parts promptly.
3. Declining Water Quality
While chemicals are often used to purify pool water, they’re not always enough. If the water appears murky or dirty, even after chemical treatment, or if it loses clarity faster than usual, this might be due to a fault in the filtration system rather than chemical imbalance. Poor water quality despite proper chemical treatment can signal that the filter needs to be changed
4. Excessive Backwashing
As pool filters age, their internal components begin to wear out, leading to dirtier pool water that requires frequent backwashing. If you find that you’re backwashing the filter more often or cleaning it far more frequently than before, it’s a strong sign that your filter system is aging and needs replacement
When to Call a Technician
If you notice a buildup of diatomaceous earth or sand at the bottom of the pool, a complete filter replacement might not be necessary. A pool technician can help determine whether the problem is with the diatomaceous grids or the sand filter laterals, which may only need a part replacement or repair.
