Signs Your Filter Needs Cleaning
- Increased pressure on filter gauge (8-10 PSI above normal)
- Cloudy or hazy water despite balanced chemistry
- Reduced water flow from returns
- Longer pump run times needed
- Debris passing through to pool
Why Clean Filters Matter
A dirty filter strains your pump, increases energy costs, and can’t clear algae or debris. Clean filters mean clearer water, lower bills, and longer equipment life.
