The provided reference describes how to backwash a DE (Diatomaceous Earth) pool filter, not a cartridge filter. Backwashing a cartridge filter is different. The reference does not describe how to backwash a filter cartridge. Therefore, I will explain how to clean a filter cartridge, as backwashing is not the appropriate term. You clean, not backwash, filter cartridges.
To properly clean a pool filter cartridge, follow these steps:
-
Turn off the pool equipment. It's crucial to turn off the pump and filter system to prevent damage and ensure safety during the cleaning process.
-
Remove the filter cartridge. Open the filter housing, carefully remove the cartridge, and inspect it for any damage such as tears or cracks.
-
Rinse the cartridge. Use a garden hose with a spray nozzle to rinse the filter pleats thoroughly. Direct the water stream at an angle to dislodge dirt and debris trapped within the pleats. Work from top to bottom, rotating the cartridge to ensure all areas are cleaned.
-
Soak the cartridge (Optional, but Recommended). For a deeper clean, especially if the filter has accumulated a lot of oil, grease, or scale, soak the cartridge in a filter cleaning solution. Follow the manufacturer's instructions for dilution and soaking time. A typical solution involves a specialized filter cleaner diluted with water. This helps dissolve stubborn contaminants.
-
Rinse again. After soaking, rinse the cartridge again thoroughly with the garden hose to remove any remaining cleaning solution and dislodged debris.
-
Inspect and Reinstall. Once cleaned, inspect the cartridge again for any remaining debris or damage. If the cartridge is excessively worn or damaged, it should be replaced. If it's in good condition, reinstall it into the filter housing, ensuring it's properly seated.
-
Restart Pool Equipment. Close the filter housing, ensuring the lid or seal is secure, and then turn the pool equipment back on.
Important Considerations:
- Frequency: How often you clean your filter cartridge depends on pool usage and environmental factors. Generally, cleaning every 4-6 weeks is recommended.
- Chemical Cleaning: Chemical cleaning should be done less frequently than rinsing, perhaps once or twice a season, depending on the buildup of oils and minerals.
- Replacement: Filter cartridges don't last forever. They should be replaced every 1-3 years, depending on usage and maintenance.
- Safety: Always follow the manufacturer’s instructions for your specific filter and cleaning solutions.
