Replace the cartridge when you notice reduced flow, persistent cloudiness, or when cleaning no longer restores proper filtration.
Practical care and maintenance tips
- Rinse the cartridge with a garden hose to remove loose debris between cleaning cycles.
- Check seals and O-rings for wear; replace as needed to prevent leaks.
- Avoid using harsh cleaners or high-pressure washing that could damage the pleats.
