Can I replace filter parts individually or do I need a new unit?

Filter parts like cartridges and valves can often be replaced individually. However, structural damage may warrant a new unit.

Many pool filter components, like O-rings, cartridges, and valves, can be replaced individually, extending the filter's life. However, if the filter's body or main structure is damaged, or if it consistently underperforms despite multiple part replacements, investing in a new unit might be more cost-effective and efficient.
