To find your replacement filter parts: 1. First, locate your filter among the names listed on this page; then, click on its name (if you don't see your filter name listed here please email at info@poolian.com. 2. Open its parts diagram by clicking on the "Parts Diagram" link provided next to the filter name. 3. Locate your part(s) that matches name(s) and number(s) indicated on the diagram. 4. To order, check the radio button and click "Add to Cart." You can only add one part at a time to the shopping cart. Please note that some parts listed here may require direct ordering from manufacturer. You'll be electronically notified if delay in delivering your order is expected. Factory original replacement parts are expensive and for some reason, some of the parts actually cost more than brand new complete filter itself; therefore, you'll be better off buying a new filter instead of replacing a big item such as a filter tank (vessel) for instance.
