Why Replace All Four Cartridges Together?
Replacing the complete filter set at the same time can help provide:
- Balanced water flow
- Even dirt loading
- Consistent filter pressure
- Better filtration performance
- Similar cartridge life
- Easier maintenance scheduling
Mixing heavily used cartridges with new cartridges can create uneven resistance inside the filter.
Maintenance Tips
For maximum cartridge life:
- Rinse cartridges thoroughly with a garden hose.
- Clean between individual pleats.
- Avoid extremely high-pressure spray that may damage the media.
- Inspect the end caps and center cores during each cleaning.
- Replace elements that are torn, collapsed, cracked, or permanently clogged.
- Use an appropriate cartridge-cleaning solution when oils or mineral deposits are present.
- Maintain proper pool-water chemistry.
